If you are a foreign national living or working in Korea, it is important to understand that a criminal case does not necessarily end when the criminal proceedings are over.
In particular, if you are charged with drunk driving (DUI) or another violation of Korea's Road Traffic Act, immigration authorities may begin a separate review process in addition to the criminal case.
One of the most important procedures is the Immigration Offender Review.
Many people assume that once they pay a fine or complete their criminal case, the matter is over. However, Korean immigration authorities may separately review whether you remain eligible to continue your stay in Korea.
Therefore, if you have been involved in a DUI case, it is important to understand what immigration procedures may follow.

1. What Is an Immigration Offender Review?
An Immigration Offender Review is a procedure in which Korean immigration authorities evaluate how a violation of immigration laws or other Korean laws affects a foreign national's eligibility to remain in Korea.
The review is not limited to determining whether a crime occurred. Authorities also consider factors such as:
☑️ The circumstances of the offense
☑️ The seriousness of the violation
☑️ Length of stay in Korea
☑️ The individual's ties to Korea
☑️ Family relationships
☑️ The likelihood of reoffending
Not every case results in the same outcome. Each decision depends on the facts of the case and the individual's personal circumstances.
For this reason, it is important to understand that an Immigration Offender Review is a separate process from the criminal proceedings.

2. What Happens After a Foreign National Is Arrested for DUI?
When a foreign national is arrested for DUI, the criminal process usually begins with a police investigation and may continue through the prosecutor's office and the courts.
Afterward, information about the case may also be forwarded to the immigration authorities.
If immigration officials determine that further review is necessary, an Immigration Offender Review may be initiated.
▶️ During this review, authorities may consider factors such as:
• Blood alcohol concentration (BAC)
• Whether a traffic accident occurred
• Whether anyone was injured
• Whether the offense is a repeat violation
Not every DUI case is treated the same. Whether it is a first offense, whether an accident occurred, and other case-specific facts can significantly affect the immigration process.
3. What Do Immigration Authorities Review?
Immigration authorities do not simply look at the criminal penalty.
They may also evaluate:
① Your length of stay in Korea and purpose of residence | ④ The circumstances of the offense and whether you have shown genuine remorse |
② Family relationships and level of settlement in Korea | ⑤ The likelihood of reoffending |
③ Employment and financial stability | ⑥ The outcome of the criminal case |
Because all of these factors are considered together, two individuals with similar DUI cases may receive very different immigration decisions.
Supporting documents that objectively explain your circumstances may also play an important role during the review.

4. How Can a DUI Affect Your Immigration Status?
A DUI does not automatically result in the same immigration consequences for every foreign national.
Some individuals may be allowed to keep their current immigration status, while others may face administrative measures depending on the circumstances.
⚠️ Factors that may influence the decision include
• The seriousness of the accident
• The extent of any injuries
• Whether there is a history of repeated legal violations
For this reason, completing the criminal case alone should not be viewed as the end of the matter.
It is equally important to determine whether an Immigration Offender Review will take place and what additional immigration procedures may follow. Because immigration proceedings are separate from criminal proceedings, both processes should be carefully monitored.
5. How Should You Prepare for an Immigration Offender Review?
Proper preparation is essential.
Immigration authorities may review documents demonstrating:
☑️ Your employment history in Korea ☑️ Family relationships ☑️ Stable residence in Korea ☑️ Evidence of remorse and efforts to prevent future violations |
It is also important to confirm all investigation schedules and document submission deadlines and to prepare all required materials on time.
Since a DUI case can affect both criminal and immigration proceedings simultaneously, both processes should be managed together.

6. Understanding the Process Early Is Critical
When a criminal case arises, many people focus only on the court's judgment or criminal penalty. However, for foreign nationals, the subsequent Immigration Offender Review may be just as important.
A DUI may be subject to immigration review depending on the circumstances of the offense, the severity of the incident, and whether it is a repeat offense, potentially affecting a person's ability to remain in Korea.
An Immigration Offender Review is not simply a review of a criminal sentence. It is a comprehensive evaluation of a person's life, immigration status, and ties to Korea. Understanding the process early and preparing the necessary documentation can make a significant difference in the outcome.
