Extension vs. Status Change: Which Do You Need?
Before anything else, confirm you need an extension, not a status change:
- Extension (체류기간 연장) — you stay on the same visa type (e.g., E-7) but push your expiry date forward. Same employer, same visa category, just more time.
- Status change (체류자격 변경) — you move from one visa type to another (e.g., D-10 job seeker → E-7 after getting a job). See our guide on How to Change Visa Status Inside Korea.
This guide covers extensions only.
When to Apply: The Golden Rule
Submit your extension application at least 4–6 weeks before your current visa expires. For complex cases (F-2-7, F-5, or applications requiring employer participation), aim for 8 weeks.
Why so early? Immigration offices in Seoul and major cities are extremely busy, especially in spring (March–May) and fall (September–October) when student and work visa holders mass-renew. Appointment slots can fill up 3–4 weeks in advance. If you miss your slot or are turned away for incomplete documents, you could end up dangerously close to your expiry date.
Where to Apply
Extensions are processed at:
- Your local immigration office (출입국·외국인청 or 출장소) — find the office covering your district at immigration.go.kr
- HiKorea online (hikorea.go.kr) — most visa types can now be extended online without an in-person visit. Online processing is often faster and avoids queues. Recommended if your documents are straightforward.
Core Documents (All Visa Types)
- Passport (original + copy of photo page)
- Alien Registration Card (ARC) (original + copy)

The Online Extension Process (HiKorea)

- Submit — you'll receive a confirmation number
- Processing typically takes 1–3 weeks online (faster than in-person during peak seasons)
- Your updated ARC is mailed to your registered address
The In-Person Process
- Book an appointment at hikorea.go.kr → Appointment Booking, or call 1345
- Arrive at your appointment time with all documents (originals + copies)
- Submit documents at the counter — the officer checks for completeness
- Pay the fee (cash or card accepted at most offices)
- Receive a receipt — this receipt proves your legal status if your original ARC expires while processing
- Processing: 2–4 weeks for most visa types
- Your updated ARC is mailed to your registered address
How Long Is Each Extension?
| Visa Type | Typical Extension Period |
|---|---|
| E-7 | 1 year (tied to employment contract) |
| E-2 | 1 year (tied to employment contract) |
| D-2 | Duration of enrollment (1–2 semesters) |
| F-6 | 1–2 years |
| F-2-7 | 1–3 years |
| F-5 | ARC renewed every 10 years; status is permanent |
Three Mistakes to Avoid
- Applying too late. If your ARC expires before your application is submitted, you are immediately in overstay. Submit at least 4 weeks early.
- Leaving Korea during processing. If you depart Korea after submitting an extension application but before it's approved, your application is cancelled. Do not travel internationally while your extension is pending.
- Incomplete documents. Missing even one document will result in your application being rejected on the day — you'll need to return with complete documents, losing time. Use the HiKorea document checklist for your specific visa type before your appointment.
