How to Extend Your Student Visa in Korea (Without Panic)
"My ARC expires soon. Can I still stay in Korea?"
If this is your worry, take a breath. Extending a student visa in Korea is a procedure. It is not automatic, but it is manageable if you start before your stay period expires.
GoKorea Study is not an agency. We do not place students, take commission, or sell visas. This guide is free information in simple English, based on official immigration information. Rules change, and rules can vary by country, school, and immigration office, so always verify with HiKorea, Korea Immigration, your Korean embassy, and your university.
This article is information only. It is not legal or immigration advice. For your own case, confirm with HiKorea, Korea Immigration, your local immigration office, your Korean embassy, or your university international office.
The Short Answer
To extend student visa Korea permission, D-2 and D-4 students must apply before the current period of stay expires.
You can usually apply through HiKorea online e-application or by visiting the immigration office that covers your address. Office visits require an advance reservation.
For student extensions, you generally need your passport, Alien Registration Card, integrated application form, proof of residence in Korea, fee, proof of enrollment, transcript or attendance record, and proof of financial ability.
The official application window is from about 4 months before your stay expiry date until the expiry date. For HiKorea online e-application, the last accepted day is the day before the expiry date.
If you apply after expiry, you have overstayed. Overstay can lead to a penalty fine, departure order, forced deportation, and a re-entry ban.

This guide is for international students in Korea who already hold a student stay status and want to keep studying without changing status.
It mainly covers:
| Status | Common student meaning | Extension focus |
|---|---|---|
| D-2 | Degree study at a Korean junior college, university, or graduate school | Continue the same academic program and keep valid stay permission |
| D-4 | General training, often Korean language training at a university-affiliated language institute | Continue the training course and keep valid stay permission |
Before applying, check:
- HiKorea: hikorea.go.kr
- Korea Immigration official information
- Your university or language institute
- Your Korean embassy or consulate if your case also involves overseas visa issuance
- The current status-by-status immigration guidance manual
What Extension of Stay Means
An extension of stay means immigration gives you permission to remain in Korea beyond the current expiry date printed on your Alien Registration Card or stay permission. It is different from a new visa sticker from an embassy. It is also different from changing status.
| Situation | Usually this means |
|---|---|
| You are still in the same D-2 degree program | Extension of stay |
| You are still in the same D-4 language course | Extension of stay |
| You finish D-4 and enter a D-2 degree program | Change of status may be needed |
| You finish D-2 and want to job hunt | Change to another status may be needed |
For D-2 and D-4 students, immigration can review enrollment, attendance, grades, and financial ability.
When to Apply
The official application window for extension of stay is:
| Application type | When you can apply |
|---|---|
| Immigration office visit | From about 4 months before expiry up to the expiry date |
| HiKorea online e-application | From about 4 months before expiry up to the day before expiry |
This one-day difference matters. If your stay expires on the date printed on your card, online e-application is not accepted on that expiry date. For an office visit, you still need a reservation. Slots can fill up near semester periods, so start early.
HiKorea Online vs Immigration Office Visit
| Route | What to know |
|---|---|
| HiKorea online e-application | You apply online through HiKorea without visiting an office. The last accepted day is the day before expiry. |
| Immigration office visit | You visit the immigration office that covers your Korean address. You need an advance reservation. |
Your school may tell you which route to use. Before you choose, check whether your case is eligible for HiKorea e-application.
From 2026-01-02, applicants who reserve an immigration-office visit for extension of stay and certain other services must pre-report employment information online through HiKorea during the reservation. This includes job type, business type, and annual income.
Documents for D-2 and D-4 Student Extension
The exact list can vary by status, school, country, and immigration office. Check the official notice before you apply. The common document list includes:
| Document | Why it matters |
|---|---|
| Integrated Application Form | Main immigration application form |
| Passport | Confirms your identity and travel document |
| Alien Registration Card | Shows your current registered stay permission |
| Proof of residence in Korea | Shows your current Korean address, such as lease or dormitory certificate |
| Fee | Extension of stay fee |
| Certificate of enrollment or standardized admission/enrollment document | Shows you are still studying |
| Academic transcript and/or attendance record | Shows your recent academic status |
| Proof of financial ability | Shows you can cover tuition and living costs |
For D-2 students, immigration may review continued enrollment, grades, attendance, and financial ability. For D-4 students, immigration may review continued enrollment, attendance or transcript records, and financial ability. Your document list may be different from a friend's list.
Fees
The standard in-person extension of stay fee is 60,000 KRW. Government- or publicly-invited national scholarship students are fee-exempt.
HiKorea online e-applications may have a discount, but the exact discounted amount must be checked on HiKorea. If a new Alien Registration Card is issued, a separate card fee may apply. From 2025-01-01, the Alien Registration Card issuance fee is 35,000 KRW.
| Item | Amount |
|---|---|
| Extension of stay, standard in-person fee | 60,000 KRW |
| Alien Registration Card issuance fee from 2025-01-01 | 35,000 KRW |
| Online e-application discount | Check HiKorea |
| Government/publicly invited national scholarship student extension fee | Exempt |
What Immigration Reviews
Extension is permission. It is not just a formality. For students, immigration can review whether you are still studying properly. This is why your school documents matter.
D-2 Students
D-2 is for degree or regular-course study at an accredited Korean junior college, university, or graduate school. For extension, D-2 students generally need proof of continued enrollment, academic transcript or grades, and proof they can cover living costs. Immigration reviews attendance and academic performance.
The total stay cannot exceed the program-level caps set for D-2. The exact period granted is decided by immigration.
D-4 Students
D-4 is for general training. The largest student group is D-4-1 Korean language trainees at university-affiliated language institutes. For extension, D-4 students generally need proof of continued enrollment, an attendance or transcript record, and up-to-date proof of financial ability.
Attendance is important. Low attendance can block extension.
If You Are Late
If you miss the deadline and apply after your stay expires, you have overstayed. Overstay can lead to:
- A penalty fine
- A departure order
- Forced deportation
- A re-entry ban
- Problems with future visa or stay applications
The overstay penalty can scale with the number of days overstayed. The maximum penalty fine listed in the immigration source is up to 30 million KRW.
Common Mistakes
Mistake 1: Waiting Until the Last Day
Online e-application is accepted only up to the day before expiry. Office visits need a reservation. Waiting can remove your options.
Mistake 2: Ignoring Attendance or Grades
For D-2 and D-4 students, recent academic record matters. Low attendance or poor grades can block or complicate the extension.
Mistake 3: Forgetting Address Proof
Proof of residence in Korea is a common required document. Prepare a lease, dormitory certificate, or other accepted document.
Mistake 4: Using Old Fee Information
The standard extension fee is 60,000 KRW, but some fees can change. Always check HiKorea before payment.
Mistake 5: Starting Work Without Permission
Extension of stay is not a work permit. D-2 and D-4 students need separate permission for part-time work through HiKorea before starting work. Unauthorized part-time work can lead to penalties.
Simple Extension Timeline
About 4 Months Before Expiry
Check the expiry date on your Alien Registration Card or stay permission. Ask your school for the current extension document list.
1-2 Months Before Expiry
Request school documents early. Prepare proof of residence and financial documents. If the exact financial amount is not stated, check the official notice.
Before the Expiry Date
Apply through HiKorea e-application or attend your reserved immigration office visit. For online e-application, apply no later than the day before expiry.
After Applying
Follow the result shown by HiKorea or the immigration office. The exact granted period is decided by immigration.

Why We Are Strict About "Before Expiry"
Many student visa problems start with a simple delay. The student thinks the school will handle it. Reservation slots fill up. A document takes longer than expected.
Use the 4-month window. Prepare documents early. Confirm with official sources.
Official truth first. No commission. No visa sales. No shortcut promises.
