“There are many foreign nationals who say, ‘I already paid the fine—why am I being blocked from extending my stay and even ordered to leave the country? I don’t understand…’
Many people assume there will be no issue because it was their first offense and no accident occurred. However, once a foreign national is caught for DUI in Korea and the fine exceeds 3 million won, the Immigration Office begins reviewing whether to restrict their stay or issue a departure order.
Because many treat it as a simple mistake, they often miss their chance to respond properly. From this stage, it becomes necessary to prepare evidence for preventing reoffending, reducing the penalty, and seeking relief from deportation.
Since it is difficult to handle these procedures alone, it is safest to respond systematically with the help of a legal representative experienced in immigration practice.

1. A DUI Arrest for Foreign Nationals: A Single Blood Alcohol Reading Can Impact Your Stay in Korea
Foreign nationals receive the same criminal penalties for DUI as Korean citizens, but the subsequent immigration procedures can lead to far more severe consequences.
Even for a first offense, a blood alcohol concentration of just 0.08% often results in a summary order fine exceeding 3 million won, and this record is immediately reflected in the immigration control system.
The biggest problem is that the case does not end even after paying the fine. A foreign national with a criminal record is classified as a “high-risk category” during visa extension review, and many face stay restrictions or even denials of extension.
In particular, DUI is treated in the same category as sexual offenses in terms of immigration screening impact, meaning that explaining it as a “simple mistake” is rarely enough to protect one’s status of stay.
Therefore, from the moment of the arrest, it is crucial to prepare documentation proving efforts such as mitigating the sentence, preventing reoffending, and demonstrating eligibility for stay relief—before the situation escalates into a departure order.
Ultimately, because a single DUI blood alcohol reading can disrupt long-term residence in Korea, early action that includes immigration-focused defense is essential.
2. Even a Summary Order Case Can Trigger a Departure Review Depending on the Fine Amount
In most DUI cases involving foreign nationals, when the blood alcohol level is clearly measured, the case proceeds without a formal trial and results in a summary order imposing a fine.
On the surface, it may seem like a minor issue, but once the fine exceeds 3 million won, the immigration office begins a separate review of the individual’s status of stay. Even for first-time offenders with no accident, a blood alcohol concentration of 0.08% or higher often leads to a summary fine of around 4 million won.
There are real cases where individuals felt relieved after simply paying the fine, only to receive a departure order notice a few months later.
For this reason, from the very beginning, a strategic response is needed that includes organizing the circumstances of the arrest, clarifying the purpose of stay, proving the absence of reoffending risk, and preparing both fine mitigation and stay relief materials.
Even if the case ends with a summary order, what follows belongs to the realm of immigration response. To protect your visa status, you need an approach that addresses both the criminal and immigration aspects together.
3. A DUI Arrest Becomes the Starting Point for Immigration Review
When a foreign national’s DUI fine exceeds 3 million won, an immigration criminal-risk review may begin from that point forward.
According to immigration control standards, you will be classified as a review target if you meet any of the following conditions:
- A fine of 3 million won or more
- Accumulated fines of 500 million won or more within the past 5 years
- A sentence of imprisonment or higher
The most serious issue arises after the criminal penalty. Once the sentence is finalized, the record is automatically uploaded to the immigration system, and you will be required to submit explanatory documents during your visa extension or change process.
If you fail to respond properly at this stage, the process may continue as follows:
- Visa extension denial →
- Departure order →
- Re-entry ban
There are real cases where even a single conviction for sexual offenses or harassment resulted in termination of stay, and DUI is treated in the same manner in immigration review.
Therefore, from the early stages, you must prepare evidence regarding the purpose of stay, employment stability, and lack of reoffending risk, while simultaneously working on sentence mitigation and stay-relief strategies.
Ultimately, maintaining your visa status depends less on the severity of the criminal penalty and more on how persuasive your materials are during the immigration review.
4. Case Study: Preventing a Departure Order After a Foreign National Received a DUI Fine
Mr. A, a Chinese national holding an F-4 visa, was caught in a DUI checkpoint with a blood alcohol concentration of 0.09% and received a summary order fine of 4 million won.
Believing the matter was resolved after paying the fine, Mr. A was surprised when, two months later, he received both a notice of visa extension suspension and a notification that an immigration criminal-risk review had begun.
Because he had not prepared for immigration procedures from the early stages, Mr. A sought help from a legal representative. Together, they submitted an opinion letter and evidentiary materials addressing his first-offense status, employment history, need to remain in Korea, and lack of reoffending risk.
After reviewing these materials, the immigration office halted the deportation process and approved his visa extension.
This case shows that in DUI cases involving foreign nationals, paying the fine does not end the matter. What is crucial is preparing, from the very beginning, both sentence-mitigation arguments and stay-relief grounds to prevent a departure order.
5. For Foreign Nationals, What You Do After the Criminal DUI Process Determines Your Future Stay in Korea
As repeatedly emphasized, once a DUI fine exceeds 3 million won, the immigration authorities immediately begin reviewing whether to restrict visa extension or issue a departure order.
DUI is classified as a serious offense that leaves a permanent criminal record in the system—similar to sexual crimes or harassment—and even first-time offenders may face interruption of their stay.
What matters most is not simply seeking a reduction of the fine, but preparing for the immigration procedures that follow the criminal penalty.
To increase the likelihood of relief, you must strategically prepare evidence in advance showing lack of reoffending risk, employment stability, established life base, family ties, and other factors demonstrating your need to remain in Korea.
For foreign nationals, a DUI case requires a combined response to both the criminal process and the immigration process.
From drafting persuasive statements for the immigration review, to defending against a departure order, to explaining the grounds for visa extension—support from an experienced legal representative capable of handling the entire process is essential.
