⚠️ Notice: Immigration policies and required documents can vary depending on an individual’s status of stay (visa) · jurisdiction office · timing. I organized this based on the basic principles in official guidance, but for the final confirmation, contact your competent immigration office/1345. (Immigration Service)

1) ARC (Alien Registration Card) Korea = Why it’s the “must-have ID” for life in Korea

The Alien Registration Card (often called an ARC) is an official ID under the Immigration Control Act, and it’s explained as having the same legal effect as a Korean resident registration card. (Immigration Service) That’s why, to do things like the following, it becomes almost a “must-have item.”

• Opening a bank account / financial transactions
• Getting a mobile phone line (postpaid plan)
• Signing a housing contract / address move-in-related administration
• Identity verification for civil services / hospitals / insurance, etc.

---

2) “By when?” ARC application deadline (this is where delays happen a lot)

Principle: A foreigner who intends to stay for more than 90 days from the date of entry must register as an alien within 90 days from the date of entry. (Immigration Service) Also, the guidance is to make an appointment first on HiKorea and then apply at the immigration office with jurisdiction over your place of stay. (Immigration Service)

---

3) ARC registration process A to Z (for first-timers)

A. Make a visit reservation on HiKorea

• There are really many cases of “going without a reservation and being sent back.”
• Your competent office is based on your current residence (place of stay). (Immigration Service)

B. Prepare documents (common + additional by status of stay)

• The common documents are mostly fixed, and
• The “additional documents” vary by visa/situation (student, worker, overseas Korean, family, etc.). (Immigration Service)

C. Submit in person + provide biometric data (fingerprints, etc.)

When registering as an alien, it may include providing biometric information such as fingerprints and face data, and there is guidance that refusal may limit permission to stay. (Easy Law)

D. Pay the fee

• As of January 1, 2025, the issuance fee for the Alien Registration Card increased to KRW 35,000 (issuance with an embedded IC chip, based on the mobile ARC). (Immigration Service)
• The payment method is stipulated by law as cash or a token/voucher proving cash payment, so “bringing cash” is the safest. (Law.go.kr)

E. Receive the receipt → receive the card

After submission, the time until you receive the physical card may vary depending on season/jurisdiction (longer during peak times).

---

4) ARC common required documents: the “4 essentials” (the basic backbone)

According to official guidance, the core basic submission documents are as follows. (Immigration Service)

✅ Common 1) Passport (original)

• If possible, bringing a copy of the passport bio page can speed up the intake process (may be requested depending on office/case).

✅ Common 2) Proof of residence (Residence proof)

• A lot of applications get rejected due to “address proof.” (More details in #5 below)

✅ Common 3) One photo (3.5cm × 4.5cm)

Photo requirements are strict. If you violate even one of the rules below, it’s the #1 on-site rejection reason. (Immigration Service)

✅ Common 4) Additional documents by status of stay (visa)

• Even in official guidance, it’s separated as “documents by status of stay (see attached file).” (Immigration Service)

---

5) Proof of residence (address verification) — the key rejection point

Residence verification can be summarized in one line like this.

“Objectively show that you actually live at this address right now.”

The most commonly used practical examples are as follows (schools/institutions usually guide the same combinations). (oia.cbnu.ac.kr)

1) Housing contract in your name (lease contract)

• The contract must show the address accurately, and
• Be sure to confirm your name (English/passport name) matches the contract

2) Dormitory residence confirmation (issued by a school/institution)

• For international students, this is the cleanest case. (oia.cbnu.ac.kr)

3) Accommodation provided by an acquaintance/company (Accommodation Provision Confirmation, etc.)

• Additional items such as a copy of the provider’s ID and supporting proof of residence may be required (varies by jurisdiction/case).

✅ Tip: If the “address notation (building/unit number/postal code)” is ambiguous, this is the most common point where the counter requests supplements.

---

6) (Reference) Common cases where additional documents are required by status of stay

From here on, it’s the area that “depends on your visa.” Still, understanding the general pattern of what gets added can reduce rejections.

● What is often required for international students (D-2/D-4, etc.)

Based on university international office notices, the following usually move as a set. (oia.cbnu.ac.kr)

• Integrated application form (template)
• Certificate of enrollment
• Proof of residence (dorm/contract, etc.)
• Fee KRW 35,000

● Cases like foreign workers (E-9/H-2, etc.) that include “medical check/proof”

In the Easy Law guidance example (worker case),

• (E-9) Business registration certificate + designated hospital drug test confirmation
• (H-2) Early Adjustment Program completion certificate + designated hospital health check report
  are guided as additional documents. (Easy Law)

---

7) ARC registration: “Top 10 most common reasons for rejection” (plus fixes)

Here, “rejection” usually means cannot be accepted / request for supplementation. The really frustrating part is that you brought all the big documents, but end up making another visit due to small details. Just checking the 10 items below greatly reduces the chance you’ll need to come back.

Rejection TOP10 summary table

Rank	Reason for rejection	How it blows up on-site	Fix (fastest)
1	Photo size/spec mismatch	“Please bring a new photo.” (white background/within 6 months/face ratio/retouching, etc.)	Retake per rules: 3.5×4.5, within 6 months, white background, no retouching/damage, etc. (Immigration Service)
2	Insufficient/unclear proof of residence	Your name not on the contract, or the address is ambiguous	Make address · your full name · type of residence clear on the contract/confirmation (for dorms, use the confirmation letter). (Immigration Service)
3	Visiting without a HiKorea reservation	“No reservation, no acceptance.”	Make a visit reservation first, then visit your competent office. (Immigration Service)
4	Application form (integrated form) not completed / completed incorrectly	Missing signature, missing date, incorrect contact info	Print and fill it out in advance + complete signature/date as well (match passport info exactly)
5	Passport info/name notation mismatch	Passport name differs from contract/enrollment documents	Standardize the English name on all documents (based on the passport)
6	Insufficient/near-expiry passport validity	May cause restrictions during stay permission/issuance process	Renew before expiry if possible (especially watch out when under 6 months remaining). (Immigration Service)
7	Fee not prepared (cash, etc.)	Panic if you can’t pay at the counter right away	Fee is regulated as cash or proof of cash payment → bring cash. (Law.go.kr)
8	Applicant not present (biometrics required)	Proxy submission limited due to fingerprint/face registration	Plan your schedule assuming you must visit in person (biometrics provision procedure). (Easy Law)
9	Missing additional documents by status of stay	“Additional documents” required depending on student/worker/overseas Korean, etc.	Check your status of stay → confirm additional documents via your jurisdiction/school notice/official guidance. (Immigration Service)
10	Confusion between “original vs. copy” for photos/documents	Original required but you brought only copies	Passport original required + prepare 1–2 extra copies of anything that might be needed. (Immigration Service)

---

8) 1-minute “final check” checklist for the day before your visit

If you just put these in your bag, the chance of having to come back due to a mistake drops a lot.

• HiKorea visit reservation completed (confirm date/time/competent office) (Immigration Service)
• Passport original (+ extra copies of bio page) (Immigration Service)
• One photo: 3.5×4.5 / white background / within 6 months / no retouching · tinted glasses · hats (Immigration Service)
• Proof of residence (contract/dorm confirmation/accommodation provision confirmation, etc.) (Immigration Service)
• Integrated application form completed (including signature/date)
• Prepare the fee in cash: KRW 35,000 (increase effective 2025.1.1~) (Immigration Service)
• (If applicable) Additional documents by status of stay (enrollment/employment/medical check, etc.) (Immigration Service)

---

9) (Bonus) From 2025, a “Mobile Alien Registration Card” also became available

Starting January 10, 2025, issuance of a Mobile Alien Registration Card is guided for registered foreigners residing in Korea. (Immigration Service) The official mobile ID guidance also introduces it as “any ARC holder can apply” in terms of flow. (Mobile ID)

• IC (chip-based) ARCs are guided as a method that makes reissuance easier via tagging even after you change phones. (Mobile ID)

---

Wrap-up: The most realistic conclusion for preventing rejection

ARC registration doesn’t get rejected because “the documents are hard”—most people slip on the basics like photo · address · signature · reservation · fee. If you prepare exactly according to today’s checklist, your chances of being accepted on your first visit go up significantly.

When you start living in Korea, “get a Korea SIM first” sounds like the obvious answer—but in reality, your options split because of identity verification (PASS/mobile identity verification). The “right answer” is completely different for someone who just needs stable data, versus someone who needs everything—from delivery apps, banks, public services, to simple payments—to work smoothly.

In this post, I’ll break down (1) prepaid (2) postpaid (3) eSIM for foreigners getting a phone line in Korea using criteria that matter more than “price”: identity verification availability / required documents / length of stay.

---

1-Minute Conclusion for Foreigners Getting a Korean Phone Line: If this is your situation, this is the answer

• Travel/business trip 1–30 days:
  → eSIM (data-only) or a prepaid SIM (fast and simple)
  However, it’s safest not to expect Korean-app identity verification in most cases. (Reasons explained below) (LG U+)
• Right after entry (no ARC yet) + you just need a number/data for now:
  → Get by with prepaid using your passport (often up to 90-day options), then switch to postpaid once your ARC is issued (KT Shop Global)
• Study/work/long-term stay + PASS identity verification is essential:
  → Postpaid (monthly plan) activated with your ARC is the most stable option
  With PASS, your name (as registered with the carrier at sign-up, including formatting) may need to match exactly. (MGlobal Community)
• Keep your overseas number (OTP) + add Korean data only:
  → eSIM is the most convenient (dual SIM). But even with eSIM, identity verification can be restricted depending on the product. (LG U+)

---

First, a quick clarification: eSIM is not a “plan”—it’s a “SIM form factor”

If you lock in just one potentially confusing point, choosing becomes much easier.

• Prepaid vs postpaid = “how you’re billed”
• Physical SIM vs eSIM = “SIM form factor (chip vs embedded)”

So there can be prepaid eSIM and postpaid eSIM (depending on the carrier/product), but what’s most commonly sold to foreigners is typically a travel prepaid eSIM. (Skroaming)

---

Core Comparison Table: Prepaid vs Postpaid vs eSIM (for foreigners)

Category	Prepaid	Postpaid	eSIM (form factor)
Recommended stay length	1 day–90 days (or short-term)	3 months–long-term	Both short/long-term (depends on the product)
Typical required documents	Passport (often possible) / or ARC	ARC/residence card + payment method	Online purchase + QR, passport verification, etc. (varies by product)
Korean identity verification (PASS)	Often restricted/not available in many cases	Available (most stable)	Travel products are often restricted
Pros	Fast, no contract burden	Best for identity verification/service compatibility, better long-term value	Instant without swapping SIMs, convenient dual SIM
Cons	May run into blocks with identity verification/financial services	Higher activation hurdles (ARC/bank account, etc.), may involve contracts	Often unrecoverable if deleted / many restricted products

You can verify document/payment requirements via carrier guidance. Example: SKT states prepaid is possible with an “ARC or passport.” (T World) KT states that the automatic payment method for postpaid plans is a “Korean bank account or a Korean card.” (KT Shop Global)

---

1) Who prepaid SIM is best for

If you’re in these situations, prepaid wins

• You need internet immediately after arriving at the airport
• Your stay in Korea is short (travel/short business trip)
• You don’t have an ARC yet (early period after arrival for students/working holiday)
• Korean online identity verification is not “immediately” essential

For prepaid activation, documents are usually checked like this

• SKT explicitly states that prepaid service is available with an ARC or passport. (T World)
• KT Global Shop also indicates that prepaid can be activated with a regular passport. (KT Shop Global)

But “a prepaid number = PASS identity verification” is not guaranteed

This is the most common wall foreigners hit when using prepaid.

• “I have a 010 number—why won’t PASS/mobile identity verification work?”
  → Some products block ‘mobile identity verification (carrier-linked)’ even if you have a number.
  LG U+ traveler guidance states that identity verification is not available on Data eSIM, etc. (LG U+)
  SKT (roaming) traveler eSIM also states personal authentication services/payment SMS reception are not available. (Skroaming)

Exception: Some foreigner-focused dealers may support “ARC linkage”

Some foreigner-focused sellers state that they support (conditionally) linking a prepaid number to an ARC so it can be used for online verification.
Example: There are cases that guide ARC linkage with conditions such as 3+ month plans. (Sim card Korea – CHINGUMOBILE)
However, this is less a universal rule for all prepaid/all carriers and more a ‘seller/product policy.’ If your goal is identity verification, it’s safest to confirm “PASS/identity verification availability” before purchase.

---

2) Who postpaid plans are best for

Bottom line: if you need the “full Korea life set,” postpaid is the answer

If two or more of the following apply, postpaid wins by a landslide in real-life convenience.

• You frequently need mobile identity verification for delivery apps/memberships/simple payments/banking apps, etc.
• You plan a long-term stay in Korea (study/work/dependent)
• You want to use your number not as “temporary,” but as a “settling-in number”

Realistic requirements for postpaid activation

• For long-term plans, the key is typically ARC + (for payment) a Korean bank account/Korean card.
  • 10mag’s guide summarizes that monthly plans require a passport, ARC, and proof of a Korean bank account. (10mag.com)
  • KT states you can pay monthly fees via automatic transfer from a Korean bank account or a Korean credit card. (KT Shop Global)
  • A local government (Guri City) living guide also notes that a card/account issued in Korea is required. (guri.go.kr)

If you’re thinking about PASS (identity verification), “name formatting” is truly important

About 70% of foreigner identity verification problems blow up right here.

• LG U+ guidance: If your contract was opened with an ARC, you can use the PASS app’s identity verification service, but you must enter your name exactly as it was first registered with the carrier (including details like whether a hyphen exists). (MGlobal Community)

👉 So if you plan to go postpaid, make sure to ask the staff at activation “Exactly how did you register my English name (spaces/hyphens/order)?” and write it down.

---

3) Who eSIM is best for (but first, distinguish by “product type”)

eSIM is unbeatable for convenience, but for foreigners there are quite a few product-specific traps.

Good cases for using eSIM

• You want to activate instantly via QR the moment you arrive in Korea
• You want to keep your overseas number (physical SIM) while adding a Korean line (dual SIM)
• You dislike swapping/losing SIM cards

Three common eSIM traps

1) If it’s “data-only,” you can’t place calls or send SMS

LG U+ FAQ clearly distinguishes that Data Only is internet only, with no outgoing calls/SMS. (LG U+)
(Even if receiving works in some cases, “verification SMS/payment SMS” is a separate issue.)

2) PASS (identity verification) may be blocked on travel eSIM products

• LG U+ states in its eSIM product guidance that the identity verification service cannot be used. (LG U+)
• SKT (roaming) eSIM also states personal authentication services and payment SMS reception are not available. (Skroaming)

In other words, just because eSIM is convenient doesn’t mean you can “go all-in for Korean life verification” without risk.

3) In many cases, eSIM can’t be restored after deletion

LG U+ guidance: A downloaded eSIM cannot be restored once deleted, and refunds/replacements may not be possible in cases of device damage/deletion. (LG U+)

---

(Important) Whether my phone supports eSIM + whether it’s compatible with Korean products

• LG U+ FAQ says you can confirm eSIM support if you can see an EID. (LG U+)
• It also advises that if your phone has a carrier lock (country lock), unlock it in advance. (LG U+)
• And notably, LG U+ FAQ includes wording stating that Pixel/OPPO devices cannot use eSIM (this may be based on that service/policy, so reconfirm before purchase is recommended). (LG U+)

---

Recommendations by scenario: “If it’s this case, go with this”

1) Travel 3–7 days / only need maps·taxi·translation

• Recommended: data-focused eSIM (or prepaid)
• Reason: instant activation, cost-efficient. But it’s safest not to expect identity verification. (LG U+)

2) Travel 2–4 weeks + need local calls/SMS too

• Recommended: prepaid (physical SIM) with data + voice, or a travel eSIM that includes voice
• Reason: helpful for restaurant reservations/local contact
• Caution: payment verification/personal identity verification may be restricted. (Skroaming)

3) Students/working holiday: first 1–2 months after entry (waiting for ARC)

• Recommended: passport-based prepaid (up to 90-day options) → then switch to postpaid once ARC is issued
• Basis: KT guidance includes that prepaid activated with a passport is provided for 90 days. (KT Shop Global)

4) Long-term study/work + delivery apps/banking/simple payments are essential

• Recommended: postpaid (ARC-based)
• Reason: PASS identity verification is key, and guidance explains it’s available under contracts opened with an ARC. (MGlobal Community)

5) “I need a Korean number, but I must keep my overseas number (OTP) too”

• Recommended: overseas physical SIM + Korean eSIM
• Reason: optimal dual SIM setup (but if your goal is identity verification, you need to confirm whether it’s a postpaid eSIM/postpaid line that supports it). (LG U+)

6) Long-term stay, but you don’t have a Korean bank account/card yet

• Recommended: get by with short-term prepaid while preparing your account → then move to postpaid
• Basis: KT explains postpaid payment methods mainly as Korean accounts/Korean cards. (KT Shop Global)

---

If your goal is “PASS identity verification,” what you must know

1) PASS is widely used as a “carrier-based” identity verification app

In Korea, carrier-based identity verification functions like daily-life infrastructure, and even recent policy changes mention the PASS app. (Korea Joongang Daily)

2) Even if you activated with an ARC, mismatched “name formatting” can make you fail

• There are real cases/guidance stating failures can happen due to hyphen/space/order differences. (MGlobal Community)

3) Travel eSIM/data eSIM may block identity verification

• LG U+ explicitly states identity verification is not available on eSIM. (LG U+)
• SKT (roaming) eSIM also explicitly states personal authentication/payment-SMS reception is not available. (Skroaming)

---

2026 Update Check: Activation procedures may become stricter

Due to recent issues like voice phishing and illegal activations, reports say Korea has been piloting/introducing facial verification (face recognition) via PASS when activating new mobile lines. The government also reportedly explained that it “only checks the match between the photo and the real face and does not store data.” (Korea Joongang Daily)

👉 Since this change can affect procedures/requirements/time needed for foreigners as well, if you’re staying long-term, it’s safest to build a habit of double-checking carrier guidance “as of today’s date.”

---

Pre-activation checklist (dramatically lowers failure risk)

1. Confirm whether your phone is unlocked (country/carrier lock removed) (LG U+)
2. Check eSIM support (confirm EID) (LG U+)
3. Decide your priority: “data” vs “Korean number” vs “identity verification”
4. If you have an ARC, ask staff during activation and write down the registered English-name format (MGlobal Community)
5. Since eSIM may not be recoverable if deleted, keep your QR/email (LG U+)
6. If long-term, plan ahead for a Korean payment method (bank account/Korean card) as well (KT Shop Global)

---

Wrap-up: There isn’t one “right answer”—it depends on your situation

• Just need internet fast → prepaid/eSIM
• All-in on Korean life verification → ARC-based postpaid
• Dual SIM/convenience → eSIM (but 반드시 check identity verification restrictions)

In Korea, activating a phone line isn’t just a telecom issue—it’s closer to the gateway to a digital ID. If you work backward from the points where you’re most likely to get stuck (identity verification/payment/documents) using this post, you’ll drastically reduce the chance of failure.

---

Key Summary

Q1. Is eSIM always best for foreign travelers?

For most people, it’s convenient. However, travel eSIMs can restrict identity verification (Identity verification/PASS), so if your goal is Korean app verification, you need to be careful. (LG U+)

Q2. Can I use PASS identity verification with a prepaid number made with a passport?

It depends on the product/policy. Travel/data eSIMs sometimes explicitly state restrictions, while some foreigner-focused sellers guide that they conditionally support ARC linkage. (LG U+)

Q3. Do postpaid plans require a Korean bank account?

Based on carrier guidance, it’s often centered around “Korean payment methods,” such as automatic transfer from a Korean bank account or a Korean credit card. (KT Shop Global)

Q4. I activated with an ARC, but PASS doesn’t work. Why?

There is guidance stating that the registered name format (including hyphens/spaces) must match what you enter in PASS. You must input it exactly as registered. (MGlobal Community)

Q5. Can I reinstall an eSIM after deleting it?

Some providers explicitly state that deleted eSIMs cannot be restored/reissued. Before deleting, be sure to check customer support/policy. (LG U+)

Q6. I’m staying long-term—can I start with prepaid first?

Yes. In practice, it’s common to get by with prepaid during the “ARC issuance waiting period,” then switch to postpaid afterward. (10mag.com)

The most common reason for failure when preparing for a visa extension (permission to extend your stay) in Korea is simple: missing one required document (especially proof of residence), documents issued too long ago, or missing your appointment slot. (Korea Visa Extension Documents)

This guide is based on 2026 procedures and provides a practical “checklist” of required documents for those affiliated with an educational institution (international students / language trainees) or a company (employment / instructor / professional manpower). (Depending on individual circumstances, additional documents may be required, so make sure to check the official channels listed at the end.)

1) Five Basic Rules for Visa Extension (Applies to Everyone)

(1) When can I apply?

You can apply for an extension of stay up to 4 months before the expiration date, and you must apply no later than the expiry date (the day before if applying through the online civil service portal).

(2) Is the process available online?

Certain visa types allow you to apply for a stay extension via the Hi Korea e‑civil service portal without visiting in person, and there’s a 20% reduction in fees. (Immigration Service)
The Hi Korea e‑service operates on weekdays 07:00–22:00 (closed on weekends and holidays). (HiKorea)

(3) On‑site applications require an advance appointment

In principle, immigration‑related applications such as extension of stay require an online appointment. Specific exemptions (pregnant applicants, those aged 70+, etc.) are listed separately.

(4) You cannot apply while abroad

To apply for permission to stay (extension/change, etc.), you must be physically present in Korea. No proxy application is accepted while you are overseas.

(5) If your passport is close to expiring, the extension period may be shortened

According to current guidelines, your stay period may be limited by your passport’s validity. If your passport expires soon, it’s recommended to renew it first (and report the new passport afterward).

---

2) Common Required Documents (These Four Are Almost Always Needed)

The following four items frequently appear in the official list of documents required for a stay extension:

• Integrated Application Form (Form No. 34)
• Passport
• Alien Registration Card (ARC)
• Proof of Residence (Address Verification)

Additionally, documents issued abroad may require an Apostille or consular legalization. The immigration office may also add or waive certain documents during screening.

Application Fee (Reference)

According to Easy Law, the fee for permission to extend your stay is 60,000 KRW. (Easy Law)
(However, the final amount may vary depending on your personal circumstances, visa type, or whether you apply online. Always double‑check with Hi Korea or your local immigration office.)

---

3) School‑Affiliated Checklist (International Students / Language Trainees)

The following are the most common categories for foreigners affiliated with educational institutions.

A. Regular University / Graduate School Students (Usually D‑2)

[Essential Items] (According to official regulations)

• Passport
• Alien Registration Card (if applicable)
• Certificate of Enrollment
• Proof of Residence (Easy Law)

[Frequently Requested Additional Documents] (Based on university guidelines)

• Academic Transcript
• Tuition Payment Certificate
• Bank Balance Certificate (some schools waive this requirement) (dongguk.edu)

Pro Tip: Many universities allow you to issue “enrollment, transcript, and tuition payment” documents at once through the student or international portal. Request them at least 1–2 weeks in advance to avoid last‑minute delays.

---

B. Post‑Master’s/Doctoral Students Preparing a Thesis (Research / Thesis‑based Extension)

Some universities (e.g., Dongguk University) list separate requirements for students staying to prepare their thesis:

• Integrated Application Form
• Passport Copy, Alien Registration Card
• Certificate of Course Completion, Transcript
• Proof of Residence
• Advisor’s Recommendation Letter (must include research schedule, supervision details, and reason for recommendation) (dongguk.edu)

Official legal guidelines also indicate that a letter from your advisor may substitute a certificate of enrollment for thesis preparation cases. (Easy Law)

---

C. University‑Affiliated Language Institutes / Language Training (Usually D‑4‑1)

[Essential Items] (According to official regulations)

• Passport
• Alien Registration Card (if applicable)
• Certificate of Enrollment
• Proof of Residence (Easy Law)

[Frequently Requested Additional Documents] (Based on school guidelines)

• Academic Transcript
• Tuition Payment Certificate
• Financial Proof (bank balance, etc.)
• Study Plan / Program Description (for trainees)
• Proof of Residence (Lease Contract / Accommodation Confirmation) (dhu.ac.kr)

Some schools also specify minimum attendance rates (e.g., 80%) requiring submission of attendance certificates, tuition payment, and housing verification. (Sungshin Women’s University)
(Attendance criteria may vary by school or jurisdiction, so confirm with your institution.)

---

D. If the Student Is a Minor or Needs a Proxy Applicant

While visa extensions are typically filed by the student, minors under 17 may have applications submitted by a parent, guardian, sibling, or guarantor. (Easy Law)

---

4) Company‑Affiliated Checklist (Employment / Instructor / Professional Manpower)

For those employed by a company, required documents depend on your visa type (E‑series, etc.) and employment form (corporation / individual / dispatched). Fortunately, the official forms specify the required attachments for extension permits, so preparing according to the checklist below minimizes rejection risk.

---

Common Company‑Related Documents (Summary)

• Employment Contract
• Business Registration Certificate
• (For corporations) Certificate of Corporate Registration

Depending on your occupation, additional documents such as a “Guarantor Form,” “Tax Payment Certificate,” or “Certificate of Employment/Dispatch Order” may be required.

---

A. Native Speaking Instructor / Foreign Language Teaching (E‑2)

[Documents Required for Extension]

• Employment Contract
• Business Registration Certificate (and Corporate Registration if applicable)

Pro Tip: For E‑2 visas, if a “workplace change/addition” is involved, extra documents such as the hagwon establishment license are required. This article focuses on extensions only—different rules apply for job changes or multiple employers.

---

Seoul is a vibrant city where the past and present coexist harmoniously. On one side, you’ll find ancient palaces and traditional culture breathing with a thousand years of history; on the other, dazzling skyscrapers and neon lights shine day and night. This unique urban landscape captivates not only tourists but also inspires those who live in the city. If you’re visiting Seoul for the first time, you may wonder where to start. To help you plan your trip, here are the “Top 5 Must-Visit Landmarks in Seoul” you absolutely shouldn’t miss.

Through this guide, you’ll discover why each of these top attractions is so special and how to experience them to the fullest. Even if your travel schedule is tight, make sure to visit the locations below. They offer an unforgettable glimpse into the many faces of Seoul.

1) Gyeongbokgung Palace: Encounter the Grandeur of the Joseon Dynasty

Steeped in deep historical and cultural significance, Gyeongbokgung Palace is often considered the crown jewel of Seoul landmarks. Built in the late 14th century by King Taejo when he established Hanyang as the capital, it served as the main royal palace of the Joseon Dynasty and the residence of kings and their families. Although it suffered heavy damage during the Japanese invasions, it was later reconstructed during King Gojong’s reign. Today, it stands as a proud symbol of elegance and dignity in traditional Korean architecture.

One highlight you must not miss is Geunjeongjeon Hall. With its imposing columns and royal throne, this hall served as the “face of the nation.” Inside, you’ll find vividly painted dancheong patterns and intricately decorated wooden beams—a glimpse into the refined aesthetics of the Joseon royal court. Strolling through the courtyard, you can almost imagine the path once taken by kings and visualize grand royal ceremonies that once took place here.

Another highlight is Gyeonghoeru Pavilion, an exquisite pondside structure that showcases a different charm in every season. In spring, budding leaves add a touch of freshness; in summer, the green lotus leaves and cool breeze create a tranquil atmosphere; in autumn, colorful foliage beautifully reflects on the water; and in winter, the snow-covered pavilion offers serene, poetic beauty.

Visitors wearing hanbok (Korean traditional clothing) can enter Gyeongbokgung free of charge, making it common to see both locals and foreign tourists in vibrant attire capturing memorable photos. If you have extra time, explore nearby Seochon and Bukchon Hanok Village. These neighborhoods, filled with traditional houses and charming cafés, offer a tranquil contrast to the modern cityscape of Seoul.

2) N Seoul Tower: A Panoramic Night View from the Heart of the City

Rising prominently atop Namsan Mountain, N Seoul Tower (formerly Namsan Tower) is one of the most recognizable silhouettes of Seoul’s skyline. While the view is spectacular by day, it’s the nightscape that truly steals the show. Offering a 360-degree panorama of glittering city lights, it’s a favorite romantic destination for couples and a perfect photo spot for families and tourists alike.

Reaching the tower itself is part of the fun — you can take the cable car or the Namsan circular bus. The cable car ride offers a preview of Seoul’s cityscape as you ascend, building anticipation for the breathtaking view that awaits at the top. Once you arrive, purchase an observation deck ticket to enjoy the panoramic lookout and explore the tower’s restaurants, gift shops, and exhibition spaces at your own pace.

One of N Seoul Tower’s most iconic sights is the “Locks of Love.” Visitors from around the world leave padlocks inscribed with their names or messages on fences and rails symbolizing eternal love and friendship. Walking among these colorful locks, you can feel the collective dreams and emotions of countless travelers intertwined on this hillside.

Don’t miss the scenic Namsan Park walking trails surrounding the tower. Whether you stroll through the forest path or sit quietly on a bench, it’s an oasis of calm amid the busy capital. With changing seasonal foliage, it’s the perfect spot to unwind and reconnect with nature during your trip.

3) Myeongdong: The Paradise of Trendy Shopping and Street Food

When it comes to shopping and food in Seoul, Myeongdong always tops the list. From international fashion brands to K-beauty stores and accessory shops, the streets are lined with endless options for every style and taste. It’s also one of the most popular destinations among overseas travelers looking to shop for authentic “K-beauty” products.

As soon as you enter Myeongdong, the vibrant signs and bustling crowds will catch your attention. Whether it’s a weekday or weekend, the area is always buzzing, with so many foreign-language signs that it often feels like a global shopping hub. Visitors love collecting free samples at cosmetics stores, hunting for buy-one-get-one deals, and enjoying the fast-paced retail energy unique to this district.

Food lovers will also find plenty to enjoy here. The streets are packed with Korean snacks such as hotteok (sweet pancakes), tteokbokki (spicy rice cakes), fish cakes, and dumplings. From trendy cafés to traditional tea houses and famous global restaurants, there’s something for every palate. For an authentic local experience, you might try Myeongdong Kyoja, a long-loved restaurant known for its handmade noodles and dumplings.

Myeongdong Cathedral, another local landmark, adds a historical charm to the area. Its gothic architecture contrasts beautifully with the surrounding modern shops, creating a unique cultural atmosphere. Combining shopping, dining, and sightseeing all in one place, Myeongdong is the perfect destination for short-term visitors looking to maximize their time in Seoul.

4) Bukchon Hanok Village: Traditional Beauty in the Heart of Seoul

If you want to escape the city’s glittering skyline and immerse yourself in traditional charm, head to Bukchon Hanok Village. Nestled between Gyeongbokgung and Changdeokgung Palaces, Bukchon was once home to Joseon-era aristocrats. Many hanok (traditional houses) have been well preserved, allowing visitors to experience old Seoul as it once was.

Walking through its narrow alleys, you’ll be greeted by elegant wooden doors and tiled roofs that create a peaceful atmosphere. These alleyways are so picturesque that they’ve become one of Seoul’s most photographed spots. The visual contrast between traditional architecture and the modern skyline beyond makes it a powerful symbol of “the harmony between the old and the new.”

Bukchon also offers hands-on cultural experiences. From hanji paper crafts and pottery making to traditional tea ceremonies, local workshops and cafés provide opportunities to connect with Korean heritage. Some hanok even operate as guesthouses, allowing you to spend a night in an ondol (heated floor) room and truly immerse yourself in traditional living.

Since Bukchon is also a residential area, please be respectful when taking photos or exploring the alleys. Keep noise levels down, especially early in the morning or at night, and remember to respect the privacy of local residents—particularly on weekends when crowds are the largest.

5) Dongdaemun Design Plaza (DDP): An Icon of Futuristic Architecture

Dongdaemun Design Plaza (DDP) perfectly represents Seoul’s harmony between tradition and modernity. Designed by world-renowned architect Zaha Hadid, this futuristic building’s fluid, curved shape makes it an instant visual landmark. During the day, its metallic surface reflects sunlight with a silver shimmer, while at night, the LED lights create a dreamy, almost surreal aura.

The DDP serves as a major hub for exhibitions, conferences, fashion shows, and art events. During Seoul Fashion Week, designers, media, and fashion enthusiasts from around the world gather here to witness the latest trends. There are also frequent design and tech-themed exhibitions, so it’s worth checking the event schedule ahead of your visit.

The surrounding Dongdaemun area is just as lively, home to massive shopping complexes and wholesale markets that buzz with activity day and night. From fabrics and clothing to accessories, you’ll find every fashion item imaginable. Many stores stay open late into the night, making it a paradise for nocturnal shoppers. For young visitors passionate about style, Dongdaemun is a must-see for both affordability and variety.

Whether you’re exploring during the day or at night, take photos with the DDP as your backdrop—it’s a favorite spot for Instagram-worthy shots. The rooftop and nearby plazas also offer great night views of the city, so don’t forget to bring your camera or smartphone.

1) Nami Island: The Romantic Forest of ‘Winter Sonata’

Filming Story

Among all K-drama filming locations, Nami Island stands out as one of the originals. When ‘Winter Sonata’ aired in 2002, it became explosively popular across Asia, turning the metasequoia-lined path that the main characters walked into a romantic pilgrimage spot for K-drama fans worldwide. Many scenes from the drama were filmed on this island, where the snowy tree-lined paths and serene lakeside views enchanted viewers around the globe.

Travel Tips

Nami Island is located on the border of Gyeonggi-do and Gangwon-do, near Chuncheon, and can only be accessed by ferry. Take the Gyeongchun Line subway to Gapyeong Station, then transfer via taxi or bus to the dock — it’s just a 5-minute ferry ride from there. The island offers restaurants, cafés, and leisure facilities, making it perfect for a half-day trip. Its charm shines year-round: autumn foliage, snowy winter scenery, and blooming spring flowers make every visit memorable. With many international visitors, English signs are readily available.

2) Jagalchi Market & Gwangan Bridge: From ‘Train to Busan’ to ‘When the Camellia Blooms’

Busan’s Sea and Sentiment

Busan frequently appears as a backdrop for Korean dramas and films. While ‘When the Camellia Blooms’ was primarily shot in Pohang, some scenes capture a Busan-like atmosphere. Though ‘Train to Busan’ is a film, its story made the city world-famous. The drama ‘Strong Woman Do Bong-soon’ even mentions Gwangan Bridge. Many productions, including ‘Oh My Venus’ and ‘The Best Hit’, have filmed romantic seaside scenes around Haeundae and Gwangalli.

Travel Tips

When visiting Busan, the areas around Jagalchi Market, Gukje Market, and Gwangan Bridge are must-see K-drama and film shooting spots. At Jagalchi Market, you can enjoy freshly prepared seafood, while Gukje Market — also featured in the movie ‘Ode to My Father’ — offers a traditional market vibe. The night view of Gwangan Bridge has long been a popular backdrop for romantic confession scenes in dramas. The city is easily accessible by public transportation and is perfect for enjoying coastal energy and local cuisine.

3) Bukchon & Samcheong-dong: From ‘Goblin’ to ‘Crash Landing on You’

Dramatic Alleys in Central Seoul

While recent hit ‘Goblin’ is known for its Canadian locations, many key scenes were also filmed in the heart of Seoul. The traditional hanok houses and stone walls of Bukchon and Samcheong-dong perfectly captured tender conversations between the Goblin and his bride. ‘Crash Landing on You’ also features several Seoul cityscapes that fans could recognize instantly, creating moments of surprise and delight.

Travel Tips

Bukchon Hanok Village and Samcheong-dong café street pair nicely with a visit to the Gyeongbokgung Palace course. Some filming locations are hidden in quiet alleys, so searching online for “Goblin filming spots map” or “Crash Landing on You locations” can help — many fans have shared guides and travel blogs. Since some spots are on private property, it’s important to visit respectfully, take quick photos, and move along quietly.

4) Chuncheon & Gangwon-do: The Next-Generation Drama Sites After ‘Winter Sonata’

Gangwon-do’s Landscape as a K-Drama Backdrop

Gangwon-do is not only the home of ‘Winter Sonata’ — parts of ‘I’m Sorry, I Love You’, starring So Ji-sub and Im Soo-jung, were also filmed around Chuncheon and Gangchon. The region’s mix of lakes, rivers, and mountains creates a scene-stealing backdrop that attracts drama productions year-round. Located just one to two hours by car from Seoul, it’s a great destination for a day trip.

Even entertainment shows like ‘Begin Again Korea’ have showcased performances on Chuncheon’s romantic lakes. For K-drama fans, the postcard-perfect scenery and recreated photo zones offer a nostalgic and emotional experience.

Travel Tips

Near Chuncheon Station, you’ll find landmarks such as “Namchuncheon Rail Park,” “Kim You-jeong Literature Village,” and “Gangchon Leisure Area,” which still carry traces of past drama shoots. The area is easily accessible via the Gyeongchun subway line or ITX Cheongchun train within about an hour. On your trip, make sure to enjoy local specialties like Dakgalbi (spicy stir-fried chicken) and Makguksu (buckwheat noodles). In winter, you can even visit ski resorts such as Elysian Gangchon — perfect for combining cultural exploration and seasonal fun.

5) Naksan Park & Daehak-ro: Everyday Alley Charm from “Reply 1988”

Filming Along Seoul’s Naksan Area

‘Reply 1988’ captured the retro charm of Seoul’s city alleys. While the original sets were located elsewhere and some have been dismantled, the Naksan area often appeared in cameo-like scenes, evoking the same nostalgic feel. Located near Dongdaemun, Naksan Park is famous for its mural village and night views — ideal for a stroll with friends, just like a scene out of the drama.

Daehak-ro and Naksan Park are connected; a walk along the fortress trail leads to breathtaking panoramic views of Seoul. Though the 1980–90s ambiance may have faded, the charming cafés, street performances, and murals still embody the artisanal spirit of the era.

Travel Tips

From Hyehwa Station (Line 4), stroll through Daehak-ro and Maronie Park, where you’ll find small theaters and street performances. From there, walk uphill toward Naksan Park, where you’ll encounter numerous photo zones along the way. Visiting at sunset is highly recommended for a stunning night view. Though not full of massive drama sets, it’s a great place for fans to reminisce and relive the ‘Reply’ series charm amid the cityscape.

Tips for Enjoying Your K-Drama Filming Location Tour

1) Bring Drama Stills or Screenshots

If you have a favorite drama, save some still cuts or screenshots on your smartphone. At the filming site, compare the real view with the scene’s backdrop — it’s even more fun to recall the dialogue and imagine being part of the story. Try recreating a character’s pose or expression for photos and share them on social media — it’s a great way to connect with global K-drama fans.

2) Respect Local Communities

Some filming sites are actually residential neighborhoods or private properties. Being overly loud or taking photos right in front of homes can disturb residents. In many cases, “that famous wall” might belong to someone’s private house, and entering without permission can violate privacy. Always take photos quietly, express gratitude, and leave promptly.

3) Make Use of Travel Passes or Tour Packages

The Seoul city government and other municipalities sometimes provide “Hallyu Filming Site Tour Buses” or travel passes. These bundled deals include transportation and admission discounts, often with a guide sharing behind-the-scenes stories. It’s convenient for itinerary management and language support — highly recommended for K-drama enthusiasts.

Conclusion: Create Memories at the Heart of a K-Drama

If you’re a K-drama lover, there’s nothing more exciting than visiting the actual filming spots of your favorite shows. From Nami Island and Busan’s Jagalchi Market & Gwangan Bridge, to Bukchon & Samcheong-dong, Chuncheon & Gangwon-do, and Naksan Park & Daehak-ro — these destinations offer countless opportunities to relive cinematic moments. Fans can easily create their own personalized K-drama pilgrimage routes across Korea.

Remember that these filming sites are often local neighborhoods or natural areas — always be mindful and respectful of the environment and residents. The scenery also changes with the seasons, offering new beauty even if it looks different from the drama. A trip to explore K-drama filming spots in Korea is not just tourism — it’s a heartfelt journey into the stories you love, creating unforgettable memories of your own.
