If you are living in South Korea, maintaining a clean visa status is your top priority. However, accidents happen—whether it’s a late visa renewal, an unauthorized part-time job, or a minor legal dispute. This leads to the Immigration Investigation (Sabeom-simsa, 사범심사).
In this post, we’ll break down the procedure and how you can protect your right to stay in Korea.

1. What is a Korea Immigration Investigation?
The Sabeom-simsa is a formal review process by the Korea Immigration Service. When a foreign resident violates the Immigration Control Act or any Korean law (including DUI or physical altercations), the authorities must decide: Can this person stay, or should they be deported?
Common Reasons for Investigation:
- Overstaying: Missing your visa expiry date.
- Illegal Employment: Working without proper authorization or outside your visa category.
- Criminal Record: Receiving a fine (Beomchik-geum) from the police.
2. The Step-by-Step Procedure
Phase 1: Detection and Summons
Usually, this happens when you visit the immigration office for a Visa Extension or Change of Status, and the officer flags a violation in the system. You may be asked to move to the “Investigation Room.”
Phase 2: The Interview (Statement of Fact)
An officer will conduct an interview. You will be required to write a Statement of Fact explaining the incident.
Pro Tip: What you write here is legally binding. Be precise and sincere.
Phase 3: Penalty Assessment
If the violation is confirmed, you will likely receive a Notice of Fine. The amount depends on the duration of the violation or the severity of the crime.
Phase 4: Final Decision on Residency
This is the most critical part. Paying the fine doesn’t mean you’re safe. The officer will issue one of the following:
- Permission to Stay: You pay the fine and keep your visa.
- Departure Order: You must leave Korea by a specific date (usually within 30 days).
- Deportation (Forceful): Immediate removal from the country.
3. How to Prepare: Improving Your Chances
To avoid deportation, you must prove that your presence in Korea is beneficial or that leaving would cause extreme hardship.
Prepare these documents:
- Letter of Reflection: A sincere, handwritten letter in Korean or English expressing regret.
- Proof of Ties to Korea: Marriage certificates (F-6), birth certificates of children, or employment contracts.
- Petitions: Letters from Korean citizens (bosses, friends, or family) vouching for your character.
- Financial Records: Evidence of tax payments and savings to show you are a stable resident.
4. Frequently Asked Questions (FAQ)
Q: Can I extend my visa if I have a criminal record? A: It depends on the type of crime and the fine amount. Generally, a fine of 3 million KRW or higher makes visa extension very difficult.
Q: Should I hire a lawyer or an administrative scrivener? A: For complex cases (like DUIs or long-term illegal stay), professional help is highly recommended to prepare the legal arguments for your “Permission to Stay.”

Conclusion: Don’t Panic, Prepare.
Facing an immigration investigation is intimidating, but it’s not an automatic ticket out of the country. Preparation and honesty are your best tools.
