In recent years, cases involving foreign nationals being caught driving under the influence have continued to increase. In many instances, the situation begins with a casual judgment—“I thought it would be fine”—but the consequences that follow are anything but minor.
In Korea, once drunk driving is confirmed, the case immediately proceeds to a police investigation, and in many cases advances beyond a simple administrative penalty to a summary order or a full trial. For foreign nationals, such records are directly reflected as grounds for an immigration offender review, often leading to visa renewal denial or even departure orders.
A more serious issue is that many individuals mistakenly believe that paying a fine brings the matter to a close. In reality, effective relief in foreign national DUI cases requires preparation not only for criminal punishment, but also for immigration review proceedings at the same time.
If you wish to maintain your current residency status, the most effective approach is to seek professional assistance immediately after the police investigation begins—so that every subsequent step can be anticipated and strategically prepared.

1. DUI by Foreign Nationals: A Single Blood Alcohol Level Can Determine Residency Status
In Korea, penalties for drunk driving are clearly determined based on blood alcohol concentration (BAC) levels.
These standards apply equally to foreign nationals, who may face the following penalties depending on the measured level:
- 0.03% to under 0.08%: Up to 1 year of imprisonment or a fine of up to 5 million KRW
- 0.08% to under 0.20%: 1 to 2 years of imprisonment or a fine of 5–10 million KRW
- 0.20% or higher: 2 to 5 years of imprisonment or a fine of 10–20 million KRW
What is crucial for foreign nationals is that criminal penalties often lead directly to immigration consequences.
Once a fine above a certain threshold is finalized, the record is shared within the immigration system. This may result in restrictions on visa renewal, review for forced departure, or classification as a subject of an immigration offender review.
In particular, many individuals mistakenly believe that paying a fine after the police investigation ends the matter. In reality, residency review procedures begin in earnest only after the criminal judgment becomes final.
For this reason, it is essential to prepare not only for the criminal defense, but also for immigration procedures, starting immediately after enforcement.
2. After a DUI Fine, Immigration Review Is Only Beginning
When a fine for drunk driving becomes final, most foreign nationals believe that the criminal process has come to an end.
However, in Korea, this record is automatically reflected in the immigration information system and is used as a key factor in subsequent reviews of visa renewal or residency status.
In particular, when the blood alcohol concentration exceeds 0.08%, even first-time offenders may receive a fine of 3 million KRW or more, requiring special caution.
This BAC level and fine amount serve as a threshold for being classified as a “subject of concern” by immigration authorities, and there are numerous cases in which visa extensions are denied without separate prior notice.
Immigration authorities assess not only whether criminal punishment was imposed, but also:
- the purpose of stay,
- employment status, and
- family relationships,
and during this process, even minor omissions or missing documents can, in practice, result in a deportation order.
Relief in foreign national DUI cases does not end with police investigations or court proceedings. Because the decision on whether a foreign national may continue to reside in Korea is ultimately determined at the administrative stage, careful and parallel preparation at each step is essential.
3. Immigration Offender Review Begins After Sentencing Is Finalized—not at the Time of Enforcement
An immigration offender review is not a simple check of immigration records. It is a distinct procedure that independently evaluates whether a foreign national should be allowed to continue residing in Korea.
When a fine of 3 million KRW or more for drunk driving becomes final, a foreign national may be classified as a subject of an offender review, going beyond an ordinary residency assessment.
A foreign national is automatically designated for offender review if any of the following applies:
- A fine of 3 million KRW or more in a single case
- Cumulative fines exceeding 5 million KRW within the past five years
- A final sentence of imprisonment or heavier punishment
Drunk driving, in particular, is categorized as a high-risk criminal offense, making it difficult to avoid disadvantages even for first-time offenders.
At this stage, a simple letter of apology is not sufficient. Documentation must be submitted to demonstrate the legitimacy of continued residence, including:
- the circumstances of the enforcement,
- employment status,
- reasons for residence, and
- the likelihood of reoffending.
In foreign national DUI relief cases, the key issue is not the severity of the sentence, but how logically and convincingly the grounds for continued residence are explained. If you are unfamiliar with offender review procedures, seeking professional assistance from the outset can be the most practical and effective response.
4. Case Study: How Outcomes Change Once Immigration Review Starts After Criminal Proceedings
W, a Moroccan national working at a manufacturing company under an E-9 visa, was caught during a DUI enforcement operation after driving following a gathering where alcohol was consumed with acquaintances. At the time, his blood alcohol concentration was measured at 0.09%, and he was issued a summary order imposing a fine of 4 million KRW.
W believed the matter had been fully resolved once the police investigation and court proceedings were completed. However, he later received an unexpected notice denying his visa extension, along with notification that he had been placed under an immigration offender review. Because he had made no preparations following the enforcement, he was at risk of losing his right to remain in Korea.
In response, W sought assistance from a professional experienced in foreign national DUI relief cases. A response strategy was prepared focusing on substantive explanatory materials, including the continuation of his employment contract, his cohabitation with family members, and the necessity of his continued residence in Korea. Based on these submissions, immigration authorities suspended the deportation measure and approved an extension of stay.
This case illustrates that the moment one stops responding after criminal punishment is finalized, disadvantages may begin at the immigration review stage. The core of foreign national DUI relief lies not in the criminal trial itself, but in how convincingly the grounds for continued residence are explained.
5. Foreign National DUI Cases: Setting the Right Direction Early Is Key to Protecting Residency
When a fine for drunk driving becomes final, the criminal procedure may be over, but immigration review begins at that point.
In particular, if the fine exceeds 3 million KRW, even a first-time offender may be subject to an immigration offender review, with a significant risk of visa renewal denial or a departure order.
For this reason, relief in foreign national DUI cases is not limited to reducing a fine. To realistically protect one’s residency status, it is necessary to clearly explain one’s means of livelihood in Korea, purpose of residence, and efforts to prevent reoffending, and to prepare documentary evidence supporting these claims.
As emphasized repeatedly, foreign national DUI relief does not end with criminal proceedings alone.
Based on extensive experience in actual cases—including police investigations, criminal dispositions, court proceedings, and successfully preventing visa renewal denials—we provide practical, step-by-step support from the moment of enforcement through the entire immigration response process.
Rather than remaining in a state of uncertainty, we encourage you to begin preparing now to protect your right to remain in Korea.
