For foreign nationals, the real consequence of a DUI isn’t just the punishment — it’s deportation.

  For foreign nationals, even a single drink before driving can become grounds for deportation.   When a foreigner drives under the influence in Korea, it is not treated as a mere traffic violation — it is classified as a criminal offense that can also trigger immigration procedures.   Once the blood alcohol concentration exceeds the legal limit, the driver may face not only a fine or imprisonment, but also a separate administrative review that affects their visa or residency status.   In fact, there have been real cases where foreigners residing in Korea received deportation orders even after the criminal proceedings ended, making an early response crucial.   The court may close the criminal case, but the immigration review can reopen the issue from a residency perspective.   Because these procedures can be complex and difficult to handle alone, it is strongly recommended to seek assistance from a legal representative who can prepare a defense that addresses both the criminal process and the immigration implications.

1. Real Case Example: How Was a Foreign National DUI Handled in Korea?

  Case ① First-time Offender Facing Deportation… Maintained Residency Through Reduced Fine   Mr. J, a Vietnamese national, was stopped by police for driving under the influence after learning of his mother’s passing and drinking due to emotional distress.   His blood alcohol concentration (BAC) was 0.066% at the time.   After the incident, Mr. J refrained from driving and used public transportation, showing genuine efforts to prevent recurrence. He also emphasized that he had no prior criminal record and had been living diligently in Korea.   As a result, the court imposed a fine of 2 million KRW, allowing him to remain in Korea without deportation.   Case ② Minor Accident, But Sentence Reduced Through Settlement and Sincerity   Mr. S, an Indian national, caused a minor accident while driving under the influence — lightly running over a pedestrian’s foot. His BAC was 0.081%.   Initially, he received a summary order of an 8 million KRW fine, which posed a significant risk to both his stay in Korea and his future immigration plans abroad.   Mr. S reached an amicable settlement with the victim, obtained a statement of non-punishment, and submitted a personal reflection letter, petitions from acquaintances, and proof of acceptance into a Ph.D. program in Canada — demonstrating his sincerity.   The court accepted his explanation and reduced the fine to 2.5 million KRW, allowing him to avoid further immigration disadvantages.   These cases show that DUI incidents involving foreigners don’t end with criminal sentencing — they can also affect residency status and future international plans.   Because the outcome can vary greatly depending on how you respond early on, it’s crucial to seek professional legal assistance to minimize potential penalties and protect your right to stay.    

2. The Higher the BAC, the Harsher the Penalty.

  A blood alcohol concentration (BAC) above the legal limit becomes the basis for criminal penalties in Korea.   In Korean law, punishment is determined not merely by whether alcohol was consumed, but by the BAC level itself. Once the number crosses certain thresholds, penalties range from fines to imprisonment — and can become even harsher depending on whether an accident occurred or if it’s a repeat offense. 0.03% or higher: Subject to criminal charges. 0.08% or higher: Possible fine up to 10 million KRW or even several years of imprisonment. 0.20% or higher: Exceeds typical fine levels and may result in actual prison time.   If an accident accompanies the DUI, the sentence becomes even more severe.   For foreign nationals, these records can also affect future visa and residency reviews, making early response especially critical.   The BAC level remains on record, and that record can later become a key factor in determining one’s right to stay in Korea.    

3. After Criminal Sentencing, Immigration Review Begins Anew.

  For foreign nationals, thinking that a DUI case ends after simply paying a fine can be a serious misunderstanding.   If a foreigner commits a traffic violation while under the influence of alcohol during their stay in Korea, there are many cases where they become subject to deportation after receiving a criminal penalty above a certain amount.   ① Possibility of Deportation Proceedings If the court imposes a fine of 300,000 KRW or more, immigration authorities may use this as grounds to request voluntary departure or initiate forced deportation procedures.   ② Automatic Restriction or Termination of Visa Status Even without the person’s consent, the immigration office may independently decide to terminate or restrict their stay in Korea.   ③ Ban on Re-entry for a Certain Period Once a deportation order is issued, re-entry into Korea may be prohibited for a set period, and future visa issuance can also be severely limited.   Under the Immigration Control Act, these administrative decisions are made separately from the criminal trial, and once determined, they can only be challenged through administrative appeals or lawsuits, making the process far more complicated.   It is crucial to recognize in advance that a single mistake could lead not just to a fine, but to a deportation order — with long-term consequences for your stay in Korea.    

4. Foreign Nationals and DUI: Why Legal Expertise Is Essential.

  Once an incident begins, it rarely ends with simply paying a fine.   In cases involving foreign nationals and drunk driving, both criminal proceedings and immigration reviews must be handled together as part of a continuous process.   The outcome can vary greatly depending on when and how strategically you respond at each stage.   ① In the early stage, you can submit a written statement to reduce criminal responsibility or seek to have the case resolved through a summary procedure.   ② If deportation or entry restriction measures are later issued by the immigration office, it becomes necessary to file an objection or respond to the review.   ③ It is also important to prepare and submit supporting documents that explain your reason for staying in Korea and your personal circumstances.   ④ Additionally, you must ensure that all mitigating factors and sentencing considerations relevant to your situation are properly documented and presented.   Because DUI cases involving foreigners are legally and procedurally complex, it is crucial to have a strategic, stage-by-stage defense plan that reflects both criminal law and immigration requirements — rather than trying to handle everything on your own.
