F-6 — marriage migrant

The three sub-types

• F-6-1 — spouse of a Korean national. The main category.
• F-6-2 — a foreign parent raising a child of a Korean national, where the marriage has ended.
• F-6-3 — a spouse whose marriage ended through no fault of their own (death, disappearance, or divorce where the Korean spouse was responsible), who continues to have grounds to remain.

Registering the marriage

The marriage has to be legally valid in both countries. In practice that means marrying in one jurisdiction and then registering it in the other — a Korean marriage report (혼인신고) at a district office, and registration at your own country's embassy, or the reverse. Only once both registrations are complete does the marriage certificate evidence you need exist.

Allow real time for this. Apostille or consular legalisation of foreign documents, translation into Korean by an accepted translator, and processing at both ends can take several weeks.

The sponsor income requirement

Your Korean spouse must show income at or above a threshold set by reference to household size, calculated on the previous year's income. This is a genuine hurdle for young couples and for couples where the Korean spouse is a student or between jobs.

There are limited exemptions and mitigations — assets can be counted in some circumstances, and there are exceptions where a child is involved. If you are close to the line, get advice before filing rather than after a refusal.

The communication requirement

The couple must be able to communicate with each other. It is satisfied by any one of:

• The foreign spouse holding TOPIK level 1 or above;
• Completing a stage of the Social Integration Program (KIIP);
• Evidence of a shared third language at a sufficient level;
• Having lived together in a third country for a qualifying period; or
• Passing an interview at the embassy.

This surprises couples who have communicated in English for years without either formally certifying it. The cheapest fix is usually TOPIK level 1, which is a genuinely elementary exam, or a KIIP stage — which is worth doing anyway, because KIIP is on the route to F-5 and naturalisation.

Other requirements

• Accommodation — a lease or property registry document showing where you will live. It must be a real, habitable residence.
• Criminal record check and health screening for the foreign spouse.
• The Korean spouse's documents — family relation certificate, marriage certificate, income evidence, and in some cases a marriage-migrant orientation programme certificate.

What F-6 gives you

Unrestricted employment. No occupation code, no employer sponsorship, no change-of-workplace report. You can work anywhere, run a business, or not work at all. In terms of day-to-day freedom it is second only to F-5.

Initial grants are usually one year, extended in one-to-three-year blocks. Extensions look at whether the marriage is continuing and whether the sponsor income condition is still met.

How the application is actually assessed

The documents establish that a marriage exists. The interview establishes that it is genuine, and that is where F-6 applications are decided. Consular officers see a large volume of these and are looking for the same thing every time: whether two people who say they built a relationship can describe it consistently.

What that means in practice is unglamorous. Keep evidence of the relationship as it happens rather than assembling it afterwards — messages over time, photographs with other people in them and across more than one occasion, travel records showing visits in both directions, and any record of meeting each other's families. A file of one weekend's photographs taken the month before applying is worse than nothing, because it looks like what it is.

Expect the couple to be asked separately about ordinary facts: how you met, what the other person does for work, who else was at the wedding, where you lived. Inconsistency on small details is more damaging than a thin file, and it is why couples who have been together for years still prepare — not because they need to invent anything, but because two honest people genuinely remember dates differently under pressure.

Where a couple met through an introduction agency, or where there is a large age gap or no shared language history, scrutiny is higher. That is not a bar. It is a reason to over-document rather than to hope the question is not asked.

The route onwards

F-6 is the shortest path to permanent residence. The F-5 sub-category for spouses of Korean nationals has a substantially shorter residence requirement than the general route — years rather than the standard five — and naturalisation by marriage is available on a similar timescale.

KIIP is the practical accelerator. Completing the programme satisfies the language and social-integration requirements for both F-5 and naturalisation, and it is free.

If the marriage ends

This is the hardest part of the F-6 system and worth understanding before you need it. If the marriage ends, your status is not automatically lost — but continuing to hold it depends on establishing that you are not at fault, or that you are raising a Korean child, which moves you into F-6-2 or F-6-3.

If you are in this situation, get specialist help immediately. There are legal aid services and multicultural family support centres (다문화가족지원센터) in every region, they are free, and they deal with exactly this.
