A visa extension in Korea is not automatic — you have to request it before your current permission to stay runs out. According to the Immigration Office’s HiKorea guidance, you can apply anywhere from 4 months before your expiration date up to the expiration date itself. Missing that window does not end your options, but it does mean a penalty applies.
This guide covers who needs to apply, when the application period opens and closes, where to submit your case, and what the Immigration Office looks at before approving an extension. It also explains what happens if your permitted stay expires before you file. Every fact here comes directly from the official HiKorea and Immigration Service pages, so where those pages do not publish a fee or a processing time, this guide says so instead of guessing.

Who Needs a Visa Extension in Korea
If you are in Korea and want to keep staying after your current period of stay ends, you need permission for extension of stay. HiKorea states that a foreigner shall receive permission for extension of stay if he or she desires to stay continuously in Korea past the current expiration date.
The rule as published applies broadly: HiKorea states that anyone who currently holds valid permission to stay and wants to continue living in Korea past the expiration date shall receive permission for extension of stay. What changes from person to person is the paperwork you need to bring, based on your specific qualification.
- You currently hold valid permission to stay in Korea.
- You want to remain in Korea past your current expiration date.
- You are applying either as the principal applicant or through an authorized agent.
⚠️ Extension of stay is separate from Foreigner Registration. If you plan to stay more than 90 days total, you must also register as a foreigner within 90 days of entry, unless you qualify for an exemption.
When to Apply for a Visa Extension in Korea
Timing matters. HiKorea’s guidance is specific: you must apply before 4 months from the current expiration date up to the expiration date. In other words, the application window opens 4 months before your stay ends and closes on the day it ends.
- Check your current expiration date on your registration or permit.
- Count back 4 months from that date — this is the earliest you can apply.
- Submit your application any time between that date and the expiration date itself.
⚠️ Applying exactly on your expiration date is still within the allowed period, but it leaves no room for delays if the Immigration Office asks for more documents.
Where and How to Apply
You, or an authorized agent acting on your behalf, must prepare the documents required for your specific qualification and submit them to the Immigration Office that has jurisdiction over you.
| Method | What it involves |
|---|---|
| In person | Submit your prepared documents directly to the Immigration Office that has jurisdiction over you. |
| Booking a visit | The Immigration Service website allows you to reserve an online appointment before visiting an office in person. |
You should confirm which Immigration Office has jurisdiction over your case before preparing your visit. If you prefer to see an officer in person, the Immigration Service website separately offers a way to book that visit online.
Which documents you need is determined by your visa qualification, not by a single universal list. HiKorea publishes a qualification table specifically so applicants can check the requirements that match their own visa category before they go.
What the Immigration Office Looks At, and What Happens After
The core requirement stated by HiKorea is simple: you must show that you desire to stay continuously in Korea and that you meet the document requirements listed for your qualification. Beyond that, the published guidance does not break down a separate list of review criteria.
The HiKorea page does not publish a processing time or a validity period for the new permission once granted. Because this depends on your visa category and individual case, you should confirm the expected timeline directly with the Immigration Office handling your application, rather than assume a fixed number of days.
It also helps to remember that HiKorea’s page focuses on the mechanics of applying — who can apply, what window to apply in, and where to send your documents — rather than on internal review standards. If you want to know how your specific case will be evaluated, that is a question for the Immigration Office handling your file, since it is not spelled out in the general public guidance.
⚠️ The application fee for extension of stay is not listed on the official guidance page. Check the current cost with your Immigration Office before you submit your application.
What Happens If Your Stay Expires Before You Apply
If your permitted stay expires before you submit your extension application, you can still apply afterward, but you will not avoid a consequence. HiKorea states plainly that anyone applying for the extension after the expiration date shall pay a penalty according to Article 25 of the Immigration Act.
The guidance does not publish the exact amount of that penalty, so do not assume a fixed figure. Confirm the current penalty amount with the Immigration Office if you are already past your expiration date.
⚠️ Applying late does not automatically mean your extension is refused — but it does mean a penalty applies, so it is better to apply inside the normal window whenever possible.
Common Mistakes and What Depends on Your Case
Most problems with a visa extension in Korea come from timing or paperwork, not from the rule itself.
- Waiting until the expiration date to check requirements, instead of starting within the 4-month window.
- Using a generic document checklist instead of the qualification table for your specific visa type.
- Assuming the fee or processing time is the same for every visa category, when the official guidance does not publish a single fixed figure.
- Not confirming which Immigration Office has jurisdiction over your case before preparing documents.
- Forgetting that Foreigner Registration, required for stays over 90 days, is a separate procedure from extension of stay.
Because requirements depend on your qualification, the office you are assigned to, and your individual case, always confirm details for your own visa type before you submit anything.

Apply between 4 months before your current expiration date and the expiration date itself. This window comes directly from HiKorea’s extension of stay guidance.

You can still apply, but HiKorea states that you must pay a penalty according to Article 25 of the Immigration Act. The exact amount is not published, so confirm it with your Immigration Office.
Where do I submit my extension of stay application?
Submit your documents to the Immigration Office that has jurisdiction over you. You can also book an office visit online through the Immigration Service website.
How much does a visa extension in Korea cost?
The official guidance page does not list a fee. Check the current cost with your Immigration Office before you apply.
Do I need to do anything else besides extending my stay?
If you are staying more than 90 days total, you must also complete Foreigner Registration within 90 days of entry, unless you are exempt. This is a separate requirement from extension of stay.
A visa extension in Korea depends on timing more than anything else, so mark your 4-month window as soon as you know your expiration date.
