For a Korean citizen, a DUI (Driving Under the Influence) usually ends with a fine and a license suspension. But for a foreign national, the legal battle doesn’t end in the courtroom. It ends at the Immigration Office.
In South Korea, a DUI conviction is one of the most common reasons for visa cancellation and forced deportation (강제출국). If you are a foreign resident, understanding the “Immigration Review” process is just as important as your criminal defense.

1. The Strict 0.03% Limit
Korea has some of the strictest DUI laws in the world. The legal Blood Alcohol Concentration (BAC) limit is 0.03%. To put this in perspective, even a single glass of beer can put you over the limit.
- 0.03% – 0.08%: Up to 1 year in prison or a fine up to ₩5,000,000.
- 0.08% – 0.20%: Up to 2 years in prison or a fine up to ₩10,000,000.
- Over 0.20%: Up to 5 years in prison or a fine up to ₩20,000,000.
2. The “3 Million Won” Rule: The Threshold for Deportation
The most critical thing to remember is the 3 Million Won Rule. According to the Korea Immigration Service guidelines, you are likely to face a deportation order or a departure order (출국명령) if:
- A single fine of ₩3,000,000 or more is imposed.
- Your total fines exceed ₩5,000,000 within the last 5 years.
- You are sentenced to imprisonment (even with a stay of execution).
Since most DUI fines for a first offense (over 0.08% BAC) start at ₩5,000,000, almost every DUI case involving a foreigner carries a high risk of deportation.
3. The Secondary Battle: Disciplinary Review (사범심사)
Even if you pay your fine and think everything is settled, you will eventually be summoned by the Immigration Office for a Disciplinary Review (Sabeom-simsa). This usually happens when you try to extend your visa or when the prosecution notifies Immigration of your conviction.
During this review, the officer will decide whether to:
- Allow you to stay (Permission to Stay).
- Order you to leave voluntarily (Departure Order).
- Forcibly deport you and ban your re-entry (Deportation Order).
4. How to Protect Your Life in Korea
If you have been caught for a DUI, your goal is two-fold: Minimize the criminal fine and maximize your humanitarian grounds for the immigration review.
- Criminal Stage: You must aim to get the fine reduced below ₩3,000,000. This often requires a professional legal brief highlighting your remorse, lack of prior record, and the circumstances of the incident.
- Immigration Stage: You need to prove “strong ties” to Korea. This includes family relationships (especially if you have a Korean spouse or children), stable employment, and a clean history of contribution to Korean society.
🛡️ Why You Need a Specialized Attorney
General criminal lawyers often focus only on the fine. However, for a foreigner, the fine is only half the problem. You need a legal strategy that considers your Visa Status from Day 1.
