If you were previously investigated as a suspect in Korea and left the country before the authorities could reach you, there's a chance a warrant has been issued in your name. If that's the case, you can be arrested the moment you pass through immigration.
This happens more often than people think. And the hardest part? Most people have no idea they're wanted. That was exactly the situation for the client we helped at Sugar Square Law & Advisors' K-Foreigner Center.

Case Summary
Entered Korea without knowing they were subject to a Class A warrant → arrested immediately at Incheon Airport
Contacted Sugar Square's K-Foreigner Center the same night
Attorney present during police questioning the next morning, communicating directly in the client's language
Letter of guarantee submitted → released within 24 hours
No travel ban imposed — client completed their business trip and returned home
Our client had come to Korea on a business trip. They never made it past immigration. They were arrested on the spot and taken to a police detention facility.
A Class A warrant is the most serious type of arrest warrant in Korea. Once issued, police can detain the person immediately upon discovery — no additional process required. In most cases, a travel ban is issued at the same time. This is categorically different from a Class C notification, which simply requires the person to appear for questioning.
In our client's case, they had experienced a criminal legal matter during a previous stay in Korea, but left the country believing everything had been resolved. In the meantime, the authorities were unable to reach them — and a warrant was issued without their knowledge. The warrant carried a ten-year validity period, and the moment they returned to Korea, they were arrested at the airport. Their business partner was waiting just outside the arrivals gate.
Sugar Square began communicating with the police station the same night the client was arrested. The following morning, one of our attorneys was present for the police interview.
We brought in an attorney who could communicate directly in the client's language — no reliance on an interpreter. In fact, when errors came up in the court-appointed interpreter's translations during questioning, our attorney was able to catch and correct them in real time. This made a significant difference in the accuracy of the client's statement.
Immediately after questioning, Sugar Square submitted a letter of guarantee in the firm's name. The client was released on the condition that they would cooperate with any further investigation as needed, with Sugar Square designated as the official point of contact for all legal correspondence.
In a case involving a Class A warrant, a travel ban is standard procedure. In this case, it wasn't imposed.
That outcome came down to structure. Rather than simply requesting release, we built a framework in which Sugar Square took on the role of guarantor and formally committed to ensuring the client's cooperation going forward. That made the difference.
All of this happened within 24 hours of the arrest.

👉 Check whether a warrant has been issued before you enter Korea
Being arrested at an airport is one of the most disorienting experiences imaginable — especially in a foreign country, in a language you may not speak fluently, facing law enforcement alone. Here's what made the difference in this case.
Acting fast
We were contacted the night of the arrest. That meant an attorney could be present at the very next opportunity — the police interview the following morning. In situations like this, timing matters enormously.
Communicating without barriers
At K-Foreigner Center, we don't rely on translators or interpreters. Our attorneys communicate directly in the client's language. In this case, that meant we could also identify and correct errors in the court-appointed interpreter's translations during the interview — ensuring the client's statement was accurate from the start.
Designing the right structure
Getting someone released isn't just about asking. It's about giving the authorities a reason to say yes. By positioning Sugar Square as the guarantor and formally committing to ongoing cooperation, we created a framework that made release — and avoiding a travel ban — possible.

Q1. How does a foreign national end up getting arrested at the airport?
A. It usually happens when someone was investigated as a suspect in Korea, left the country, and the authorities were never able to reach them. A warrant gets issued — and the person has no idea. If you've had any legal involvement in Korea in the past, it's worth checking your status before you come back.
Q2. What is a Class A warrant?
A. It's the most serious type of arrest warrant in the Korean system. Once issued, police can detain the person on the spot — no additional steps required. A travel ban is typically imposed at the same time. It's very different from a Class C notification, which only requires the person to come in for questioning.
Q3. What should I do if I'm arrested at the airport?
A. Call a lawyer immediately. Don't make any detailed statements before you've spoken with legal counsel. Ask for an attorney who can communicate directly in your language. K-Foreigner Center is available for urgent situations.
Q4. Is it possible to be released without a travel ban?
A. It depends on the case. In this instance, we were able to structure the release in a way that made a travel ban unnecessary — by formally committing Sugar Square as guarantor and establishing a framework for ongoing cooperation. Early intervention is what makes that kind of outcome possible.
Q5. What does K-Foreigner Center do?
A. We're a team of U.S.-licensed legal professionals and Korean attorneys working together to support foreign nationals with any legal matter connected to Korea — immigration, visas, criminal cases, divorce, inheritance, real estate, workplace disputes, and more. We communicate directly in your language, so there's no language barrier between you and the legal help you need.
