Foreigners living in Korea may suddenly realize that their visa expiration date is approaching. Missing the visa renewal deadline can lead to illegal stay, fines, or even deportation—so careful preparation is essential. In this guide on “Visa Extension Step by Step,” we’ll cover the documents required before visiting the immigration office, online application methods, fees, and key precautions. If you prepare in advance, the process isn’t as complex as it may seem. Stay informed and avoid unnecessary complications!
1) Checking the Expiration Date: When Can You Apply for an Extension?
Start Preparing 4 Months Before Visa Expiration
Most visa types (such as E-2, D-2, and D-4) allow extension applications up to 120 days (4 months) before expiration. For long-term residence visas (F-series), you may be able to apply even earlier, so check the immigration office website for details. Preparing early ensures you have enough time to supplement missing documents.
If you wait until the last minute, long queues at the immigration office may prevent you from applying on time, and overstaying even by a day can result in fines or penalties. To avoid issues, submit your application at least two weeks before your visa expires.
Check Your Passport’s Validity
If your passport is close to expiring when you apply for a visa extension, your application may be denied or your approved stay may be shorter than requested. For example, if your passport is only valid for six more months, your visa extension may only be granted for six months. Ensure your passport is valid for at least a year before applying.
2) Required Documents: General & Visa-Specific Requirements
Common Documents
- Passport (Original & Copy) – For identity verification.
- Alien Registration Card (ARC) – Necessary as proof of residence in Korea.
- Visa Extension Application Form – Available at the immigration office or online.
- Passport Photo – Taken within the last six months, meeting passport specifications (a digital file is required for online applications).
- Processing Fee – Typically ₩60,000 (₩50,000 for online applications), usually payable by card.
Additional Documents by Visa Type
- D-2 (Student Visa) – Enrollment certificate, transcript, attendance records (minimum credits completed for undergraduates), tuition payment receipt, proof of scholarship, financial documents.
- E-2 (English Teacher Visa) – Renewed employment contract, criminal background check (issued within the last six months), medical check-up results (tuberculosis and drug tests), a copy of employer’s business registration.
- F-4 (Overseas Korean Visa) – Family relationship certificate (to prove Korean descent), residence proof, income-related documents.
- E-7 (Employment Visa) – Business registration certificate of the employer, employment contract, tax withholding receipt, and tax payment records.
Each visa type has specific requirements, which can be checked on the Hi Korea website or by contacting the immigration office. Missing documents can delay the process, so prepare thoroughly.
3) Online Application Process: Using Hi Korea
Account Registration & Digital Certificate
To apply online, visit Hi Korea (www.hikorea.go.kr) and register for an account. Foreigners need a digital certificate (public authentication certificate or financial authentication certificate) to verify identity. A registered phone number or bank account in your name is required for verification. Though the registration process may seem complex, having a certificate makes future applications much easier.
Completing the Application
After logging in to Hi Korea, select ‘E-Application → Extension of Stay’ to begin your online application. Enter personal details, residence, visa type, and employer (or school) details. Required documents should be uploaded in PDF or JPG format. Note that large files—such as employment contracts or enrollment certificates—may need resizing to fit file size limits.
Paying the Fee & Submitting the Application
The final step requires paying a ₩50,000 processing fee via credit card or bank transfer (in-person applications cost ₩60,000, typically through revenue stamps). Once payment is made, you will receive a submission confirmation. Immigration officers will review your application within two weeks and notify you of the results. Once approved, your visa’s expiration date is automatically updated in the system—no need for a physical sticker or additional procedures (be sure to save a copy for your records).
4) In-Person Visits: Reservation Required
Booking an Appointment with the Immigration Office
If online application is not an option or if your visa type requires an in-person submission, you must visit the immigration office. Booking an appointment through Hi Korea is highly recommended to avoid long queues. Without a reservation, you may experience extended wait times or even be unable to apply on the day. Arrive on time, take a ticket, and wait for your turn at the service desk.
Document Review & Interview on Site
During your visit, an immigration officer will check your documents and may ask additional questions about your financial situation or stay plans. After verification, you will pay the processing fee, and your extension request will be formally submitted. Some visa types may require fingerprint re-registration, so follow the instructions provided. Processing generally takes one to two weeks, and results are sent via email or mail. Your Alien Registration Card may be stamped or a sticker may be added with the new expiration date.
5) Important Tips & Precautions
Apply Before Expiration to Avoid Penalties
Even if you apply on the expiration day, you haven’t technically overstayed—but this is risky. Any system failure or missing documents could prevent same-day approval. You should apply at least two weeks in advance to avoid complications. Overstaying for even a single day can result in fines ranging from hundreds of thousands to millions of KRW, and in some cases, deportation.
Changing Visa Type Requires a Different Process
If your visa purpose changes (e.g., a D-2 student transitioning to an E-7 work visa), you must apply for a visa change instead of an extension. The process requires different documents (such as a work contract) and involves more scrutiny. If you mistakenly apply for an extension instead of a change, your application may be rejected—so verify the correct procedure beforehand.
Don’t Forget to Report Address Changes
If you move to a new residence, you must report your address change within 14 days at the immigration office or your local government office. Failing to do so can result in fines. Additionally, if your reported address doesn’t match the documents submitted for visa extension (rental contract, homestay agreement, etc.), your application may be delayed or rejected.
Conclusion: Don’t Delay Your Visa Extension—Stay Prepared
Visa extension might seem complicated, but as long as you monitor your expiration date and gather documents step by step, it’s manageable. Most foreigners staying in Korea for over six months will go through this process at least once. Keep a checklist of documents required for your visa type, coordinate with your school, employer, or landlord if necessary, and choose between Hi Korea’s online application or an in-person immigration office visit for submission.
The biggest mistake is thinking “I still have time” and postponing the process until it’s too late—resulting in fines or forced departure. Delays in visa extension could even disrupt your travel plans. A bit of advance preparation can prevent major problems.
Additionally, keep in mind that any changes in address, employer, or school enrollment must be reported to the immigration office immediately. Visa extensions are just one aspect of maintaining your legal stay in Korea. Hopefully, this guide clarifies what steps to take before your visa expires, making the process smooth and hassle-free!
