The criminal case has been resolved, so why is my visa extension being blocked—and why is deportation even being mentioned?
For F-4 visa holders, the most confusing and shocking moment after a DUI often comes at this stage. Many assume that because there was no accident and it was a first offense, everything will be fine. However, once the fine exceeds 3 million KRW, a separate set of immigration standards begins to apply.
From this point on, immigration authorities internally review whether to deny visa renewal or initiate deportation procedures. In many cases, these disadvantages begin without the individual even being aware of them. By the time they realize what is happening and try to respond, the decision may already have been made.
An F-4 visa DUI is therefore not just a criminal matter. It is a continuing issue that directly affects one’s immigration status and stability of stay, making advance preparation essential.
Even after paying the fine, immigration consequences can persist. Because these issues are difficult to handle alone, anyone who wants to prevent visa denial or forced departure is far better off developing a response strategy from the outset with a legal professional who understands immigration law.

1. The higher the blood alcohol concentration, the more severe both the criminal penalty and the immigration consequences.
In Korea, a blood alcohol concentration (BAC) exceeding 0.03% is legally considered driving under the influence, and penalties vary depending on the level.
- 0.03–0.08%: Up to 1 year of imprisonment or a fine of up to 5 million KRW
- 0.08–0.2%: 1–2 years of imprisonment or a fine of 5–10 million KRW
- 0.2% or higher: 2–5 years of imprisonment or a fine of 10–20 million KRW
A BAC of 0.08% or higher also meets the threshold for license revocation, and if the level is high or there is a prior DUI record, the likelihood of actual imprisonment increases.
However, the issue does not end there. If an F-4 visa holder receives a DUI fine exceeding 3 million KRW, the Immigration Office conducts a separate review of the individual’s eligibility to remain in Korea, independent of the criminal punishment. During this process, a denial of visa extension or a deportation order may be issued.
2. For foreign nationals, immigration review proceeds separately even after the criminal process is completed.
Receiving a fine for a DUI as an F-4 visa holder does not mean the matter is over. For foreign nationals, the Immigration Office conducts a separate review of whether the individual remains eligible to stay in Korea, independent of the criminal disposition.
During this process, factors such as
- prior DUI history,
- whether an accident occurred, and
- the individual’s attitude and response at the scene
are all taken into consideration. In practice, there are many cases where, even after the criminal proceedings have concluded, the matter proceeds to a deportation review.
In particular, much stricter standards are applied in cases involving school zones, uninsured driving, or attempts to flee after drinking. These situations are treated far more seriously than ordinary violations.
For this reason, a stable and effective response requires looking beyond the level of criminal punishment alone and assessing the entire context of the incident, including its potential impact on one’s immigration status.
3. If a traffic accident occurred, whether a settlement was reached directly affects the immigration decision.
When an F-4 visa DUI case involves a traffic accident, the most critical point of response is whether a settlement is reached with the victim.
While factors such as the extent of the victim’s injuries, insurance coverage, and on-site handling are also considered, in practice it is the existence of a genuine settlement that has the greatest impact—not only on the criminal trial but also on the immigration review.
If a settlement is reached smoothly, the likelihood of a reduced fine increases, and the Immigration Office may view the case favorably as evidence that the individual did not evade responsibility.
Conversely, a merely formal attempt at settlement or a response lacking sincerity can work against the individual during a deportation review.
Therefore, in F-4 visa DUI cases accompanied by a traffic accident, settlement should be treated as a core element of the stay-maintenance strategy, and it must be approached carefully and deliberately from the earliest stage.
4. If the case proceeds to a formal trial, the submitted materials can determine the outcome of one’s stay.
In F-4 visa DUI cases, there are situations where the prosecution requests a formal trial, or where the individual involved seeks a trial on the grounds that the fine is excessive.
At this stage, what matters is not expressing a sense of unfairness, but preparing evidentiary materials that support both sentence mitigation and continued lawful stay.
For example:
- A settlement agreement with the victim
- A detailed letter of remorse
- A written pledge to prevent reoffending
- A certificate of completion for traffic safety education
- Petitions or letters of support from family members or an employer
Such materials serve as evidence not only in the criminal trial but also in immigration review, where authorities assess responsibility and social ties.
If the case proceeds to a formal trial, it already indicates that the matter is no longer simple. Accordingly, a strategy that integrates criminal defense and immigration response is essential.
Rather than responding to each procedure separately, organizing materials and planning responses with the entire process in mind is key to increasing the likelihood of maintaining one’s status of stay.
5. Strategic response plays a decisive role in the final immigration outcome.
In F-4 visa DUI cases, assuming the matter ends with just a fine can cause you to overlook the real problem.
Once the fine exceeds 3 million KRW after criminal punishment, the Immigration Office conducts a separate review to determine whether the individual may continue to hold their status of stay. In many cases, this leads to a denial of visa extension or the initiation of deportation procedures.
The issue is that most foreign residents become aware of this process far too late.
Thoughts like “It’s my first offense, so it should be fine,” or “I paid the fine, so it must be over,” often result in missed opportunities to respond—by the time action is taken, immigration review or even a departure order may already be underway.
That is why effective response requires looking beyond the initial criminal case and preparing in advance for the immigration review that follows.
We provide structured assistance that links criminal defense with immigration matters, rather than treating them separately.
When you work with a professional from the early stages—deciding what evidence to submit and how to explain the necessity of continued stay—the outcome can make a meaningful difference.
