A small omission during an extension or a change of status delays the review or turns into an immigration problem. Two principles cover most of it: track the expiry date early, and get the document list for your own status from the office handling your case.
The five that actually catch people
- Applying after the permitted stay has expired — before and after are not the same procedure
- Missing records or the wrong authentication format — employment, enrollment or family documents, and how foreign papers are translated, notarized or apostilled
- Not reporting an address change after moving
- Staying on the old status after the activity changed — graduating and then starting work is the common one
- Leaving Korea mid-review without checking what departure does to the application
Start months before expiry
Work through HiKorea and your school or employer, and keep originals, copies, translations, notarization and apostille in one checklist. The apostille has to come from your home country, which makes it the slowest item on the list.
Address, status and travel each need their own check
- Address — the reporting deadline and the office differ by status
- Status — moving from D-2 study into work, or from H-1 into longer-term employment, means confirming the permitted status and completing the change before the new activity starts
- Travel — if a trip overlaps a pending extension, ask immigration what departure does to the application and what you need to re-enter
If a deadline has already passed
Do not wait and hope. Contact immigration, explain the facts, and follow what they tell you. Fines and other consequences vary with how long it has been and the circumstances, and the options narrow the longer it runs.
What to check now
- Your expiry date — put a reminder three months ahead
- Whether any document has to come from your home country
- Whether you have moved or changed activity recently
Requirements and exceptions vary by status, office and date. Confirm yours through HiKorea or the Immigration Contact Center at 1345. The case-by-case version is on the WeBring blog.
