Changing visa status in Korea means applying for official permission to switch from your current status of stay to a different one, so you can legally do things your present status does not allow. Foreigners must receive this permission before they take part in any new activity that is not relevant to, or not permitted under, their current status of stay. This is different from simply staying longer under the same status, which is called an extension of stay.
This guide explains what a change of status of stay actually means, who is required to go through it, when you must apply, and how it differs from an extension. All of the information below comes from the official HiKorea Immigration/Stay Guide, so if your case is unusual, confirm the current requirements with your local Immigration Office before you act.

Who Needs to Apply for Changing Visa Status in Korea
You need to apply for changing visa status in Korea whenever you want to do something your current status of stay does not permit. A status of stay only covers the activities tied to it, so moving to a different kind of activity requires official permission first, not just a notification to the office.
The official Immigration/Stay Guide gives four concrete examples of when a change of status applies.
- A C-2 status holder who wants to invest in Korea needs to change status to D-8.
- A D-3 status holder who wants to take a job after one year of training needs to change status to E-8.
- A D-4 status holder who wants to study in Korea needs to change status to D-2.
- A foreigner who marries a Korean citizen can change their status of stay to F-2, and this applies regardless of what residence status of stay they currently hold.
⚠️ These are examples given by the official guidance, not a complete list. The rule is about the activity you want to do, not a fixed set of visa types.
Change of Status vs Extension of Stay: What Is the Difference
A change of status lets you switch to a new type of status of stay, while an extension only lets you continue the status you already have. Extension of stay is for a foreigner whose permission of stay is expiring and who wants to keep staying in Korea under the same status. Change of status is for a foreigner who wants to start a new kind of activity that the current status does not cover.
As a general rule for change of status, you are expected to leave Korea, obtain a new status that matches the activity you want to do, and then re-enter Korea under that new status. A limited change of status without leaving Korea is only possible when you can meet the requirements of the new status while still in the country, and it is granted only after passing a rigid examination by the Immigration Office.
| Topic | Change of Status of Stay | Extension of Stay |
|---|---|---|
| Purpose | Switch to a different status to do a new activity | Continue the same status you already have |
| Usual requirement | Normally leave Korea and re-enter with the new status; limited in-country change only after a rigid examination | Apply while still inside Korea; no need to leave |
| When to apply | Before starting the new activity (A-1, A-2, A-3: within 30 days of a change in position or duties) | Before your current permission of stay expires |
| Late application | Not stated on the official guidance page | Penalty under Article 25 of the Immigration Act if you apply after the expiration date |
When You Must Apply and How Long You Have
Timing matters for changing visa status in Korea, because permission must be granted before you start the new activity, not after you have already begun it.
- In general, you must obtain permission to change your status before you begin the new activity you are not currently permitted to do.
- If you hold A-1, A-2, or A-3 status and your position or duties change, you must receive permission to change your status within 30 days of that change.
⚠️ The 4-month application window and the penalty under Article 25 of the Immigration Act described above apply to extension of stay, not to change of status. Do not assume they carry over.
How to Apply: Documents and Process
The application process is straightforward on paper, but the documents you need depend on your current status and the status you are applying for.
- Identify the new status that matches the activity you want to do.
- Check the required documents for that status using the status table on the HiKorea Immigration/Stay Guide page, since document lists differ by status.
- Prepare the required documents yourself, or have an appointed agent prepare and submit them on your behalf.
- Present the documents to your local Immigration Office before you start the new activity.
- If you are applying without leaving Korea, be ready for a rigid examination to confirm you meet the requirements of the new status.
⚠️ The official guidance page does not list a fee for changing status of stay, so check the current cost with your local Immigration Office before you submit your application.
What Happens After You Apply, and Common Mistakes
Once your documents are submitted, the Immigration Office decides whether you meet the requirements for the new status. If you cannot meet the requirements without leaving the country, the general rule applies: you must depart Korea, obtain the new status, and re-enter before doing the new activity.
- Starting the new activity before permission is granted, instead of applying first.
- Missing the 30-day deadline after a change in position or duties for A-1, A-2, or A-3 status.
- Assuming the extension deadlines and penalties apply to a change of status, when the official sources describe them separately.
- Not checking the specific document list for the target status before visiting the Immigration Office.
Frequently asked questions
What is the difference between changing visa status in Korea and extending my stay?
A change of status lets you switch to a different type of status to do a new kind of activity, while an extension only lets you continue your existing status past its expiration date. The application timing, and whether you may need to leave the country, are handled differently for each.
Do I have to leave Korea to change my visa status?
As a general rule, yes: you are expected to leave Korea, obtain the new status, and re-enter. A limited change of status without leaving is possible only if you can meet the requirements of the new status while still in the country, and only after passing a rigid examination.
How long do I have to apply after my situation changes?
You must get permission before you start the new activity. If you hold A-1, A-2, or A-3 status and your position or duties change, you must apply within 30 days of that change.
Can I change my status of stay after marrying a Korean citizen?
Yes. The official guidance lists this as an example of change of status, allowing a change to F-2, and it states this applies regardless of what residence status of stay the person currently holds.
Where do I submit the application?
You submit the required documents to your local Immigration Office. This can be done by you in person or by an appointed agent on your behalf.
Changing visa status in Korea always starts with permission from your local Immigration Office, not with the new activity itself. Because required documents, deadlines, and whether you must leave the country depend on your current and target status, confirm the details for your specific case on the official HiKorea page before you apply.
