Extending your period of stay in Korea: step-by-step 2026 guide
When to file, where to file, which documents you need, how much the fee is, and what happens if you overstay — complete under the 2026 rules.
Every residence status in Korea comes with a specific period of stay, printed on the alien registration card (ARC / 외국인등록증) or on the entry stamp placed in the passport at the border. When that period is about to run out and there is still a valid reason to remain in the country, the applicant must complete the procedure for extension of the period of stay (체류기간 연장허가) before the expiry date arrives. This article walks through the entire process as it applies in 2026 — from timing and filing channels to documents, fees, and the consequences of letting the deadline pass.
1. What a stay extension is
An extension of the period of stay means prolonging the time you are allowed to remain in Korea under the residence status you already hold, without leaving the country and without switching to a different status. In other words, nothing about the category of your stay changes — only the date by which you must leave or renew again. The procedure is set out in Article 25 of the Immigration Act (출입국관리법 제25조).
An extension is distinct from a change of residence status (체류자격 변경 / Article 24). A change of status means moving to a new category altogether — for example, a student on a D-2 visa taking up skilled employment under E-7 — whereas an extension simply adds more time within the same category. Knowing which of the two procedures applies to your situation is the first step, because the legal basis, the supporting documents, and the review standards differ between them.
Preparing a stay-extension application?
The Autofill service fills in the integrated application form (통합신청서) and related forms to the exact format of the Korea Immigration Office — accurately, in minutes.

The extension procedure applies to every foreign national residing lawfully in Korea who needs to stay beyond the date their residence status expires — workers, international students, investors, family members, and holders of every other status category alike. If you intend to remain in the country past your current expiry date, an extension (or a change of status, where appropriate) is the only lawful way to do so.
When to file: submit the application before your residence status expires — per common practical guidance, typically within the 4 months before the expiry date, but not too far in advance. There is no specific legal provision fixing the earliest permitted filing date; however, filing late, after the expiry date has passed, is a violation of the law and will be penalized. The safe approach is therefore to treat the expiry date as a hard deadline and file comfortably ahead of it within that window.
3. Where to file
There are two official channels:
- 1. Online via HiKorea (www.hikorea.go.kr) — Most common residence statuses are eligible for online filing through the HiKorea portal (하이코리아 / HiKorea), the Korean government's e-government gateway for immigration services. This is the most convenient method, as it requires no in-person visit to an office: the application is lodged, and the fee paid, entirely online.
- 2. In person at the Immigration Office (출입국·외국인청 / 출입국관리사무소) — Applications must be filed at the immigration office that has jurisdiction over the place of residence you have registered, not just any branch. Certain special cases and more complex residence statuses are required to file in person rather than online, so it is worth confirming which rule applies to your category before relying on the portal.
4. Documents to prepare
The basic file, applicable to most extension cases, consists of the following:
- Extension application form (통합신청서 — the integrated application form): downloadable from HiKorea or available at any immigration office counter.
- A valid passport.
- The alien registration card (ARC / 외국인등록증).
- A portrait photo (3.5 × 4.5 cm, white background — the standard Korean passport-photo specification).
- Documents proving that you still meet the conditions of your residence status — this is the most important part of the file, and it varies by status category. For example: an employment contract for E-7, a certificate of enrollment for D-2, proof of ongoing business activity for D-8, family relation records for F-6 and F-1, and so on. This is the part of the application the reviewing officer scrutinizes most closely, because it answers the central question of whether the original basis for your stay still exists.
- The application fee (see the section below).
Depending on the case, the reviewing authority may request additional material: proof of where you live (a housing lease contract / 등기부등본 property register extract), tax records, or financial documents. Having these ready in advance can prevent a request for supplementary documents from delaying the decision.
5. Fee and processing time
Extension fee: ₩60,000 (for 2025–2026, unchanged).
Note: if the ARC needs to be reissued after the extension is granted, a separate card-reissue fee of ₩35,000 applies on top of the extension fee.
Processing time: normally 2 to 4 weeks from the date the complete file is submitted. For some complex status categories, or during peak filing periods when offices are handling a high volume of applications, processing can take longer. Importantly, while the application is pending, your stay continues to be treated as lawful — provided the complete, valid file was submitted before the expiry date. This is why filing on time matters so much: a timely, complete submission protects your legal status throughout the waiting period, whereas a late one does not.
6. Consequences of overstaying
Overstaying (체류기간 초과 / overstay) means continuing to remain in Korea after your residence status has expired without a valid extension or change of status in place. It is a violation of the Immigration Act, and it can lead to:
- An administrative fine of ₩100,000 to 1,000,000, calculated according to the number of days of violation — the longer the overstay, the higher the penalty.
- Refusal of an extension or of a new residence status — the reviewing authority may reject an application from anyone with a history of overstaying, which means a single lapse can jeopardize future filings.
- A departure order or deportation.
- A re-entry ban — depending on the severity of the violation, the person concerned can be barred from entering Korea for anywhere from 1 year to many years.
- Long-term damage to the immigration record: a history of overstaying is logged in the immigration system and can create difficulties for future visa procedures — including F-2 residence, F-5 permanent residence, and naturalization.
