Relevant laws
Immigration Act Articles 47 and 48 (Investigation; Request to Appear and Questioning of Suspects)
Immigration officers can investigate foreigners suspected of being subject to deportation and, if necessary, request them to appear for questioning. Statements are recorded in a statement record, which must be read to the suspect or shown to them, and they must be asked whether anything needs correcting. The statements of a person who does not understand Korean must be interpreted by an interpreter.
Immigration Act Articles 101, 102 and 105 (Criminal Referral; Notice of Fine; Failure to Pay and Referral)
Immigration violation cases cannot be prosecuted without a criminal referral from the head of the immigration office. If an investigation confirms an offense, the head of the office can issue a notice to pay an immigration fine, and must refer the case immediately if it appears to warrant imprisonment without labor or a heavier sentence. If the fine is not paid within 15 days of receiving the notice, the case must be referred, but not if a deportation order has been issued.
Immigration Act Articles 94 and 95 (Penalties)
People who overstayed, engaged in other activities without permission for activities outside their status of stay, or hired people without a work-eligible status of stay, among others, face imprisonment of up to 3 years or a fine of up to KRW 30 million. People who changed workplaces without permission or hired such foreigners, or violated the duty of alien registration, among others, face imprisonment of up to 1 year or a fine of up to KRW 10 million.
Immigration Act Article 99-3; Act on the Employment of Foreign Workers Article 20
Illegal employment and hiring foreigners without permission to change workplace are subject to joint penalty provisions (양벌규정), so the corporation or business owner can also be fined. An employer punished for violating the Immigration Act or similar laws can be restricted from hiring foreign workers for 3 years from the date of the violation.
Statutes are summarized. The official Korean text is available at the Korea Law Information Center (law.go.kr).
What is an immigration violation review?
An immigration offender (출입국사범) is a person found to have violated the penalty provisions of the Immigration Act. Common examples on the foreigner's side are overstaying, working or changing workplaces without permission, and failing to meet the alien registration duty. Companies and their representatives who hire foreigners not allowed to work are also immigration offenders.
These cases are investigated by the immigration office, not the police. Even if the police learn of a case first, they must hand it over to the office, and it cannot be prosecuted without a referral from the head of the office (Article 101). So the office's investigation and review effectively decide the direction of the case.
What to keep in mind during questioning
If needed for the investigation, the office will ask you to appear for questioning and record your statement in a statement record. The record must be read to you or shown to you, and you must be asked whether anything was written incorrectly. If you ask for additions or changes, those must also be recorded. If your Korean is limited, ask for an interpreter.
It is important to explain truthfully how the violation happened. If there were circumstances such as your company not giving you the extension documents, missing the deadline because you were hospitalized, or being misinformed about the procedure to change workplaces, bring messages, medical certificates or documents that show this.
The review can lead to several outcomes
If a violation is confirmed, the case may end with a notice to pay an immigration fine, you may receive a departure order after the notice (Article 68(1)(5)), or, if the violation is serious, it may lead to a deportation order or a criminal referral. If the case appears to warrant imprisonment without labor or a heavier sentence, the head of the office must refer it immediately.
If you pay the immigration fine, the case does not go to criminal trial, but the violation record may be considered in later reviews for extension of stay or change of status of stay. When you receive a notice to pay an immigration fine, you must decide within 15 days whether to pay or dispute the violation.
When a company is investigated
Hiring a person without a work-eligible status of stay is punishable by imprisonment of up to 3 years or a fine of up to KRW 30 million, and hiring a foreigner who has not obtained permission to change workplace is punishable by imprisonment of up to 1 year or a fine of up to KRW 10 million. A corporation can also be fined under the joint penalty provisions, but can avoid this if it exercised considerable care and supervision to prevent the violation (Article 99-3).
In the investigation, what matters is whether you knew the worker's status of stay, whether you checked their residence card, and how many people you hired for how long. If you are punished, you may be restricted from hiring foreign workers for 3 years, which can be a bigger burden than the fine itself. Organize your hiring documents, verification records and staffing agency contracts before giving your statement.
Duties companies must follow at all times
Before hiring, check the worker's status of stay, period of stay and permitted scope of activities using their residence card, and keep a record. In some cases, such as student (D-2) or job seeker (D-10) status, the person needs permission for activities outside their status of stay to work.
If a foreign employee is dismissed, resigns, dies or cannot be reached, or if important terms of the employment contract change, you must report it to the office within 15 days. Failing to do so can lead to an administrative fine (과태료) of up to KRW 2 million (Articles 19 and 100). You must not discriminate against workers because they are foreign, and if you provide a dormitory, you must give information such as its structure, location and size before signing the contract.

Frequently asked questions
If I pay the immigration fine, is there no problem with my stay?
If you pay the immigration fine, the case does not go to criminal trial, but if the head of the office considers departure measures appropriate after the notice, a departure order can be issued (Immigration Act Article 68(1)(5)). Even if you can continue staying, the violation record may be considered in your next review.
What happens if I cannot pay the immigration fine on time?
If you do not pay within 15 days of receiving the notice, the head of the office must refer the case for prosecution, and criminal proceedings begin (Article 105). If you pay before the referral, the case will not be referred. If it is hard to pay within the deadline, contact the office in advance.
If the company did not know the worker's status of stay, will it avoid punishment?
The company can argue that it had no intent, but this is more likely to be accepted if it can show with records what checks it made. Keeping records of checking residence cards and hiring documents is the most reliable preparation.
What about the unpaid wages of employees caught in a raid?
Pay for work done must be paid regardless of status of stay. Settling wages and severance pay before the employee is detained or leaves reduces disputes later.
