Immigration decisions arrive as a single sheet of paper with a box checked and a short reason. An extension refused. A change of status denied. A departure order (출국명령) with a date on it. There is rarely a conversation, and the officer who hands it over is not the person who decided it.
What follows is not a discussion but a set of procedures with deadlines, and the deadlines are short. Three separate routes exist, they can be combined, and choosing between them is the first decision — usually made in the same week the paper arrives.
→The Three Routes
They differ in who decides, how long they take, and how much of the original decision they can reach.
| Route | Who Decides | Deadline |
|---|---|---|
| Objection (이의신청) | The Minister of Justice, through the immigration authorities themselves | Short and specific to the decision type — for a deportation order (강제퇴거명령), 7 days from service |
| Administrative appeal (행정심판) | The Administrative Appeals Commission — an administrative body, not a court | 90 days from learning of the decision, and 180 days from the decision itself |
| Administrative litigation (행정소송) | The administrative court | 90 days from learning of the decision, and 1 year from the decision itself |
An objection (이의신청) is fastest and costs nothing, but it asks the same institution to reconsider its own decision, which limits what it realistically achieves. An administrative appeal (행정심판) is quicker and cheaper than court and can review whether the decision was appropriate, not only whether it was lawful. Administrative litigation (행정소송) is slower and more expensive, and it is the only route that produces a judgment.
The 90-day period is the one that ends most cases. It runs from the day you learn of the decision — not from the day you decide to do something about it, and not from the day you find a lawyer.
→Suspension of Execution (집행정지): The Part That Cannot Wait
Filing a case does not stop the decision from taking effect. Korean administrative law works on the opposite principle: a disposition remains operative while it is being challenged unless a court orders otherwise.
For most disputes that is an inconvenience. For immigration it can be the end of the matter. A person removed from Korea while their case is pending has, in practical terms, lost — the case may continue, but they are not in the country to benefit from it, and their employment, tenancy, and family arrangements have already collapsed.
Winning a case you are no longer in the country for is a technical victory and nothing more.
The answer is an application for suspension of execution (집행정지), filed together with the main challenge rather than after it. The court asks whether execution would cause damage that is difficult to repair, whether there is urgency, and whether suspension would seriously harm the public interest. Removal from the country, separation from a spouse or child in Korea, and the loss of a business built over years are the kinds of facts that speak to the first question — but they have to be pleaded with documents, not asserted.
→Find Out What the Decision Actually Says
Most refusal notices give a reason in a phrase. That phrase is not the reasoning; it is the summary of it. Challenging a decision without knowing what is in the file means arguing against a version of it you have constructed yourself.
An information disclosure request (정보공개청구) is the standard way to obtain the underlying material, and it is available to foreign nationals. What comes back is often decisive: an investigation record, a report from a workplace inspection, a statement someone gave about you, a criminal disposition you assumed had been resolved. Cases turn on discovering that the decision rests on a fact that is simply wrong.
Two further checks are worth making at the same time. Where an entry ban (입국금지) has been imposed, its existence and period can be confirmed — and it is not unusual for a person to discover a ban they were never told about. And where a decision followed an immigration offence resolved by a penalty notification (통고처분), the terms of that disposition frequently explain what happened next.
→What Actually Persuades
Immigration decisions are discretionary, which cuts both ways. Discretion is hard to attack as unlawful, but it is exactly what an administrative appeal (행정심판) can review for appropriateness — and discretion exercised without weighing the relevant circumstances is itself a ground of challenge.
- Proportionality. The consequence against the conduct. A first, minor, and remedied violation set against removal from a country where a person has lived for a decade is the classic shape of this argument
- Facts left out of the balance. A Korean spouse, a child in Korean school, a business employing Korean staff, tax and pension contributions over years. If these were in the file and the decision does not engage with them, that is the argument
- Factual error. The strongest ground where it exists. A misidentified person, a charge that ended in a non-prosecution disposition, an employment record attributed to the wrong company
- Procedural failure. Reasons that are not reasons, an opportunity to be heard that was not given, a notice served in a way that did not reach you
Note what is absent from that list: an explanation of how difficult the situation is for you personally. It matters, but only as it attaches to one of the grounds above.
→Practical Points for Foreign Nationals
Where the refused decision was a visa application made at a Korean embassy or consulate abroad, be aware that whether a foreign national outside Korea can bring administrative litigation (행정소송) against it has been contested, and the answer has not been uniform. Challenges to decisions made inside Korea — refusals of extension, refusals of a change of status, departure and deportation orders — sit on firmer ground.
Do not leave the country voluntarily on the assumption that it will be treated as cooperation and make matters easier. Departure after a decision can affect both your ability to pursue the case and your position on return, and it is a step to take with advice rather than instead of it.
Finally, keep the paper. The envelope, the date it arrived, the notice itself, and anything handed to you at the office. The 90-day clock runs from the day you learned of the decision, and in a genuine dispute about when that was, the person holding the documents is the one who can prove it.
