Marrying a Korean After Overstaying: F-6 Status and the Visa Route

Many people meet a Korean partner and start planning a wedding after their permitted stay has already run out. The two most common questions are "If we register the marriage, can I just stay?" and "How big is the fine?" The short answer: marriage and residence are separate issues, and if you are overstaying, the route to marriage migrant (F-6) status inside Korea is closed in principle. What matters most is how you leave and how you apply for a visa again.

Key points

• A marriage does not cure an overstay. The penalty and the ground for deportation remain.
• Change to spouse of a Korean national (F-6-1) is for people lawfully staying in Korea. An overstayer in principle must leave and get a visa at a Korean mission abroad.
• Leaving under deportation creates a ground for entry ban for 5 years, so the way you leave affects your later visa application.
• The marriage visa review centers on whether the marriage is genuine, together with income, Korean language and housing requirements.

1. Marriage and residence are judged separately

Within marriage migrant (F-6) status, spouse of a Korean national (F-6-1) is for a foreigner whose marriage has been validly established in Korea and who wants to stay to continue married life with a Korean citizen. A valid marriage is only the starting point for this status; it does not undo the time you have already overstayed.

As of October 2026, under Article 94 of the Immigration Act, a person who stays on past their permitted period without an extension faces up to 3 years in prison or a fine of up to KRW 30 million. The same violation is also a ground for deportation. In practice, a fine notice or departure measures are considered depending on the length and circumstances of the overstay; see the overstay fine guide for how each period is handled.

2. Can you switch to F-6 inside Korea?

The residence manual sets the target for change to F-6-1 as "people lawfully staying in Korea." It then says that the following people in principle cannot change status and must leave and enter on a visa issued by a Korean mission abroad:

1. Holders of short-term visas (visa waiver, tourist/transit, and temporary news coverage through short-term employment)
2. Overstayers (including people who entered illegally or used forged or altered passports)
3. People granted an extension of stay for the purpose of departure
4. People with general criminal records (simple fines excluded)
5. People who received Miscellaneous (G-1) status while in one of the situations above

However, if change in Korea is judged unavoidable because of pregnancy, childbirth or raising a child born to the couple (adopted children excluded), it may be allowed after review. Even under this exception, the period granted is up to 1 year. Because the exception depends on review, first gather documents proving the reason (medical certificate, birth records and so on) and ask the competent immigration office.

3. How you leave changes the way back

• Deportation: Article 11 of the Immigration Act lists a person who left after a deportation order and for whom 5 years have not yet passed as a ground for entry ban. Even if you prepare a marriage visa, this period comes first.
• Departure order: This can be given to a person who has a ground for deportation but wants to leave voluntarily at their own expense. If you do not leave by the deadline in the order or break its conditions, a deportation order is issued.
• Length of entry restriction: Whether an entry restriction follows a departure order or voluntary departure, and for how long, is not set as a number in the Act. Check whether any restriction remains on your record before applying for a visa.

The voluntary departure process is covered in the voluntary departure guide, and lifting an entry ban in the entry ban removal guide.

4. Applying for a marriage visa after leaving

1. Your Korean spouse invites you. A visa for married cohabitation requires an invitation from the spouse, who becomes your guarantor.
2. Check the international marriage guidance program. For designated countries, the inviting spouse must attach a completion certificate or write the completion number. Exemptions include cases where the foreign spouse stayed lawfully for 91 days or more on long-term status and can prove the couple dated during that time.
3. Prepare documents. These include the invitation, guarantee, statement of marriage background, income and housing documents, communication requirement documents and proof of the relationship (photos together, family photos, social media chats and so on, up to 5 A4 pages).
4. Get the visa at the mission and enter. A spouse visa may be issued at the head of mission's discretion as a single-entry visa for a stay of 90 days or less; in that case you must register as a foreigner and extend your stay within 90 days of entry.

5. What the genuineness review looks at

To judge whether the marriage is genuine and a normal married life is possible, the mission may review and confirm:

• How the couple met and their intent to marry, and whether the marriage is valid under both countries' laws
• Whether the inviting spouse invited another spouse within the last 5 years
• The inviting spouse's income, and mutual exchange of health and criminal record information
• Basic Korean language ability of the foreign spouse
• Housing where the couple can live together on a lasting basis (places such as study rooms, motels and greenhouses do not count)

If the couple has a child together, the income and communication requirements are waived. If a visa is refused, you may reapply after 6 months from the refusal date, or earlier if there is an urgent reason such as childbirth. It is best to explain the overstay honestly rather than hide it.

6. What an administrative agent can do

We check whether a change of status in Korea is possible, prepare departure order applications, help organize the statement of marriage background and relationship history, prepare visa documents such as the invitation and guarantee, and translate foreign documents. Criminal defense and litigation representation are outside the scope of an administrative agent and we do not handle them.

The order of steps matters when you are marrying and sorting out your stay, so check your records and documents before you leave.
