A DUI arrest involving a foreign national does not end simply with paying a fine. Once a fine above a certain amount is confirmed, immigration authorities separately re-evaluate the person’s status of stay.
If the fine exceeds 5 million KRW, many foreign nationals face disadvantages during the visa extension review, and in some cases, this has even led to deportation procedures.
The problem is that most people receive these immigration notifications only after the criminal process has concluded. While assuming that the case ended quietly through a summary order, their residency status may already be at risk.
Therefore, even after the criminal penalty is finalized, the real work of securing relief for foreign nationals caught driving under the influence begins at that point.
From the start, both sentence mitigation and strategies for maintaining residency must be reviewed together. Because this process is difficult to handle alone, seeking assistance from a legal professional is essential to avoid missing the critical timing for a successful response.

1. A DUI Fine Is Not the End for Foreign Nationals
When a person is caught driving under the influence in Korea, the level of punishment varies depending on their blood alcohol concentration (BAC).
0.03% ~ less than 0.08%
Imprisonment: Up to 1 year
Fine: Up to 5 million KRW
0.08% ~ less than 0.20%
Imprisonment: 1 to 2 years
Fine: 5–10 million KRW
0.20% or higher
Imprisonment: 2 to 5 years
Fine: 10–20 million KRW
Up to this point, the penalties apply equally to both Koreans and foreigners.
However, for foreign nationals, the situation can change dramatically after a DUI arrest.
It does not end simply by paying the fine—immigration authorities may start a separate review of the person’s residency status.
In practice, the following situations often lead to immigration disadvantages:
- Receiving a summary order imposing a fine of 5 million KRW or more
- Causing an accident while intoxicated, especially if there is a victim
In such cases, immigration officials may conduct a renewed suitability review, which can result in visa extension denial or even a deportation notice.
Many foreign nationals mistakenly believe the case is over once they pay the fine.
But in reality, immigration-related responses after the fine often matter even more.
Relief for a DUI involving a foreign national requires evaluating not only the potential for sentence reduction but also the possibility of maintaining legal residency.
If criminal and immigration issues are not considered together from the outset, serious problems may arise during visa extension.
2. After Receiving a Summary Order, You Must First Decide How to Respond
In DUI cases involving foreign nationals, a summary order is often used to conclude the case quickly and simply. However, once you accept the fine, it can have direct consequences on your future residency status—so you should avoid making a hasty decision.
For example, if the penalty exceeds a certain threshold, immigration authorities may request documents for a criminal-risk review or ask for additional materials during the residence-status review. Whether or not you accepted the summary order without contest can also become an important factor.
Therefore, from the beginning of the case, you must carefully consider whether to ① pursue a formal trial to seek sentence reduction, or ② accept the fine as issued. At the same time, it is wise to prepare residency-related documents in advance.
Commonly used supporting materials in practice include:
- Evidence of the family’s financial situation and children’s education in Korea
- Employer confirmation letters and proof of long-term employment
- A handwritten statement of remorse and a commitment to preventing reoffense
- A legal representative’s written opinion on residency matters
Additionally, your attitude during questioning and the content of your statements can affect later immigration procedures, so legal guidance is often needed from the very start.
Relief for a DUI involving a foreign national does not end with the criminal process. The key is to simultaneously prepare for both sentence reduction and maintaining your residency status.
3. Residency at Risk After a Fine… A Real Case Where Sentence Reduction Protected Visa Extension
G, a Canadian national, was working at a Korean manufacturing company on an E-9 visa when he was stopped at a DUI checkpoint on his way home after a company dinner. His blood alcohol concentration measured 0.084%, which exceeds the license-revocation limit, and he ultimately received a summary order imposing a 7 million KRW fine.
Although it was his first offense and he believed the case had ended quietly, just a few weeks later he received a notice from the immigration office informing him that he was subject to a criminal-risk review, along with a warning that his visa extension could be denied.
He then sought assistance from a legal representative specializing in DUI relief for foreign nationals. Together, they prepared and submitted a written opinion emphasizing ① the necessity of his continued stay, ② his role in supporting his family, and ③ the low likelihood of reoffending.
As a result, through a formal trial, his sentence was reduced and the fine was lowered to under 2.5 million KRW. Immigration authorities later determined that he remained suitable to stay in Korea, and G was granted a visa extension, allowing him to continue living in the country.
This case illustrates that if you stop responding after the criminal process ends, serious immigration consequences may arise. It also shows that preparing both sentence-reduction arguments and a residency-preservation strategy is essential in DUI cases involving foreign nationals.
4. For Foreign Nationals, DUI Relief Starts With Addressing Post-Fine Immigration Issues
Although DUI cases involving foreign nationals may appear to end with the payment of a fine, in reality, they can become the starting point of serious immigration problems.
When the penalty exceeds certain thresholds, immigration authorities conduct a separate review of the individual’s residency status, and many cases subsequently lead to visa extension denial or even deportation notices.
Therefore, focusing solely on the criminal process is not enough. While seeking sentence reduction to lower the fine, you must simultaneously prepare supporting documents and position statements that strengthen the possibility of extending your stay.
Because immigration proceedings depend heavily on timing and coherent reasoning, establishing a clear strategy early is essential when relief is needed after a DUI involving a foreign national.
