An exit ban for DUI in Korea affecting foreign nationals is more common than many people realise.
Strictly speaking, for foreign nationals the Immigration Control Act uses the mechanism of a departure suspension (출국정지) under Article 29, although English materials often describe it as an “exit ban.” A drunk-driving arrest does not automatically end with a fine and a flight home — Korean authorities may restrict departure for the duration of the criminal proceedings when the statutory grounds are met.
Understanding when this happens, how long it lasts, and what options exist is essential for any foreign resident or visitor caught up in a DUI case.
When Does a DUI in Korea Trigger an Exit Ban?
The Road Traffic Act (도로교통법, effective 2026-04-02) classifies drunk driving by blood-alcohol concentration and by outcome.
Under the current Road Traffic Act, even a first-time DUI can carry significant statutory penalties: for BAC 0.03% to below 0.2%, Article 148-2 provides imprisonment of 1 to 5 years or a fine of KRW 5 million to KRW 20 million; higher BAC levels, refusal to comply with testing, and DUI causing injury or death carry heavier ranges.
The gravity of the charge directly affects whether an exit ban or departure suspension will be sought.
For foreign nationals, the legal basis is Article 29 of the Immigration Control Act, which applies the grounds and procedures in Articles 4, 4-2 and 4-5 by reference. In a DUI case, the key grounds are usually:
| Stage | Legal Basis | Maximum Duration | Typical DUI Scenario |
|---|---|---|---|
| Criminal investigation | Art. 29 + Art. 4② by reference | 1 month (extendable) | Police inquiry after arrest; prosecutor review pending |
| Criminal trial ongoing | Art. 29 + Art. 4①-1 by reference | 6 months per order (renewable) | Indictment filed; first or second hearing scheduled |
| Emergency exit ban | Art. 29 + Art. 4-6 by reference | Immediate, pending approval within 12 hours | DUI causing death or serious injury; flight risk at the port |
For a routine DUI with no accident, investigators typically do not seek an exit ban unless the suspect’s ties to Korea are weak and a voluntary departure seems likely before the case concludes. The situation changes significantly if the DUI caused an accident, if the BAC was very high, or if the suspect attempted to leave the country after the incident.
The Emergency Exit Ban: What Happens at the Airport
Articles 29 and 4-6 of the Immigration Control Act allow investigators to request an emergency departure suspension at the port of departure — before any formal order from the Ministry of Justice — when the suspect is facing a crime punishable by three years’ imprisonment or more and there is a risk of flight or evidence destruction. A DUI causing serious bodily harm or death may fall within this category.
Investigators notify immigration officers directly, and the traveller is stopped at passport control. The investigating agency then has six hours to submit a formal approval request, and if the Ministry of Justice does not confirm within 12 hours, the restriction must be lifted.
For foreign nationals, encountering this at the airport — often while holding a plane ticket — is a serious and disorienting situation. Having legal counsel who can communicate with both the investigating authority and the Ministry of Justice within that narrow window is important.
How Long Can the Ban Last for a Foreign National?
Once an indictment is filed, a departure restriction can be renewed in six-month blocks under Article 4-2, as applied to foreign nationals through Article 29. Korean criminal trials, particularly those involving accident-related DUI, can take anywhere from several months to over a year.
A foreign national’s visa may expire during this period, creating a secondary problem: continued lawful residence in Korea while the case is pending. In practice, the court or immigration authority can acknowledge the pendency of the criminal case when the person requests a visa extension or a stay-of-deportation, but this requires a formal application and supporting documentation.
The Korea Supreme Court has confirmed that the freedom to leave the country is constitutionally protected and that departure restrictions must be proportionate and case-specific. The cited case concerned an exit ban in a tax-arrears context (Supreme Court Decision No. 2012두18363, 2013. 12. 26.), but its proportionality reasoning may also support challenges to disproportionate departure restrictions in criminal cases, including DUI matters where the actual flight risk is low.
Challenging or Lifting the Exit Ban
Article 4-5 of the Immigration Control Act, as applied through Article 29 for foreign nationals, gives the subject a direct route: file a written objection with the Minister of Justice within 10 days of receiving the restriction notice. The Ministry must issue a decision within 15 days. If the objection is dismissed, an administrative lawsuit (행정소송) seeking cancellation of the departure restriction remains available in the administrative courts.

What Foreign Nationals Should Do Immediately After a DUI Arrest
The first 48 hours after an arrest can be critical for custody and early investigation decisions. For non-detained suspects, however, referral to prosecutors and indictment or summary proceedings may take longer depending on the case.
Whether the case is referred to the prosecutor as a summary matter, whether bail conditions include a travel restriction, and whether a departure suspension is formally sought all depend on actions taken in the early stage.
Communicating promptly and clearly through a Korean criminal defence lawyer, gathering evidence of strong ties to Korea (employment, family, long-term residence), and addressing any administrative issues with the visa early can all affect how the case proceeds.

Frequently Asked Questions
Can a foreigner be banned from leaving Korea after a DUI arrest?
Yes. For foreign nationals, the legal mechanism is technically a departure suspension under Article 29 of the Immigration Control Act. Article 29 applies the Article 4 grounds by reference, including criminal investigation and pending criminal trial situations. A DUI charge can qualify, particularly if the blood-alcohol level was high, the offence involved an accident, or the suspect is considered a flight risk.
How long does an exit ban last for DUI in Korea?
During the investigation stage the initial departure suspension is generally up to one month and may be extended. Once an indictment is filed and the trial begins, the restriction can be imposed for up to six months at a time under Article 4-2, as applied to foreign nationals through Article 29, with further extensions possible until the case is concluded.
How can a foreigner challenge or lift a DUI exit ban in Korea?
Article 4-5 of the Immigration Control Act, as applied through Article 29, allows the subject to file a written objection with the Minister of Justice within 10 days of receiving notice of the restriction. The Ministry must decide within 15 days. Separately, an administrative lawsuit seeking cancellation of the departure restriction can be filed in the administrative courts.
In practice, demonstrating that the criminal proceedings are concluding or that there is no realistic flight risk strengthens any application for early release.
