F-6 Marriage Visa Extension in Korea
Documents & Process [2026]

Overview: F-6 Extension

The F-6 (결혼이민) visa is Korea's marriage-based residency status. It covers three sub-types — F-6-1 (married to a Korean national), F-6-2 (raising a child of a Korean national), and F-6-3 (divorced or widowed with qualifying circumstances) — and is typically granted for 1–2 years at a time. Renewal is straightforward when the qualifying relationship is intact and the required documents are in order.

Unlike work visas, F-6 carries open work authorization. Extension applications are filed at the local immigration office in Korea (출입국·외국인청/사무소). There is no annual cap or lottery; every qualifying applicant who submits a complete file is eligible for renewal.

When to Apply

You should submit your F-6 extension application 1 to 3 months before your current ARC (Alien Registration Card) expiry date. This window gives immigration officers enough time to process the application without risk of a status gap, and also allows time to gather additional documents if requested.

Processing time at most immigration offices is 2–3 weeks. During peak periods (end of year, spring) it can extend to 4 weeks. You will receive a text notification when a decision is ready.

Where to Apply

Applications are submitted in person at the immigration office or Hi Korea center (하이코리아) nearest to your registered address. You can also use the Hi Korea online system (hikorea.go.kr) for some straightforward F-6-1 renewals, though in-person submission is recommended whenever you have complex documents or changes in circumstances.

Documents by Sub-type (F-6-1 / F-6-2 / F-6-3)

F-6-1: Married to a Korean National

This is the most common renewal type. The core requirement is demonstrating that the marriage is real and ongoing. All documents must be originals or certified copies; documents issued more than 3 months before submission may be rejected.

F-6-2: Raising a Child of a Korean National

F-6-2 renewal focuses on demonstrating that you are the primary caregiver of a child with Korean nationality, and that the caregiving relationship is continuing. Marriage to a Korean national is not required.

• Passport and current ARC
• Child's family register (가족관계증명서) confirming Korean nationality and the parental relationship
• Household registration (주민등록등본) showing you and the child at the same address
• Child custody evidence: school enrollment certificate (재학증명서), medical records (진료기록), immunization records, daycare enrollment — any evidence showing you actively care for the child
• Income proof: salary certificate or bank statements to show financial ability to raise the child
• Application form, photo, KRW 130,000 fee

If there is a custody dispute or shared custody arrangement, bring any relevant court orders. Officers will assess whether the applicant is genuinely the primary caregiver, not merely nominally listed.

F-6-3: Divorced or Widowed — Qualifying Circumstances

F-6-3 covers foreigners who are no longer married to their Korean spouse due to divorce or death, but who meet one of the protected qualifying conditions. Renewal requires proving the qualifying condition still exists — the burden of evidence is higher than for F-6-1.

• Passport and current ARC
• Divorce certificate (이혼확인서 / 이혼판결문) or Korean spouse's death certificate (사망진단서)
• Documentation proving divorce was not the foreigner's fault: police report (사건사고사실확인원), hospital/medical records, domestic violence shelter records, court judgment, or notarized statement from the Korean spouse
• Child's family register and proof of continued custody/caregiving (주민등록등본, school or medical records)
• Income or asset evidence — since there is often no Korean sponsor, the foreign applicant's own income or savings must be shown
• Any ongoing legal proceedings (court filings, hearing records) related to divorce, custody, or domestic violence
• Application form, photo, KRW 130,000 fee

Income Verification Requirements (2026)

Since 2025, Korean immigration authorities formally require that the Korean sponsor (or the foreign applicant, in F-6-2/F-6-3 cases) can financially support the household at or above 120% of the minimum cost of living (최저생계비). For a 2-person household, this threshold is approximately KRW 2.3–2.5 million per month in 2026 (the exact figure is adjusted annually by the Ministry of Health and Welfare).

Accepted Income Documents

• Employed sponsor: Employment certificate (재직증명서) + pay stubs (급여명세서) for last 3–6 months + bank statements
• Self-employed sponsor: Business registration certificate + income tax return (종합소득세 신고서) for the most recent year + bank statements
• Both spouses earning: Both incomes can be combined to meet the threshold; submit documents for each
• Assets in lieu of income: If monthly income falls short, documented savings of approximately 12–24 months of the shortfall can be submitted as supplementary evidence

New 2025 Rule: Korean Language Requirement Below Threshold

If the Korean sponsor's income is below the threshold (하한소득기준), immigration may request that the foreign spouse demonstrate basic Korean language ability. This is assessed through a brief conversational interview at the immigration office — not a written TOPIK test. Passing TOPIK Level 1 or higher, or showing enrollment in a KIIP (사회통합프로그램) course, can satisfy this requirement and is recommended as a precaution.

Evidence of Cohabitation & Joint Life

For F-6-1 extension, demonstrating a genuine and ongoing marriage is the central requirement. Immigration officers look for consistent, multi-faceted evidence that the couple shares a real life together — not just a legal document. No single item is mandatory; a combination of several types is most effective.

Strongest Evidence (submit at least 2–3 types)

What Does Not Help

• Simply submitting the Korean spouse's family register without accompanying cohabitation evidence
• Photos that are clearly staged, undated, or from only one occasion
• Documents that list different addresses for each spouse without explanation

Path to F-5 Permanent Residency

F-6-1 is one of the most direct routes to F-5 (영주) permanent residency in Korea. Under the F-5-2 (marriage) route, an F-6-1 holder becomes eligible to apply for F-5 after 2 continuous years of F-6-1 status — provided the marriage is still intact at the time of application.

F-5-2 Application: What You Need

• Passport and ARC
• Proof of 2 consecutive years of F-6-1 status (ARC history, re-entry records)
• Korean spouse's family register and marriage certificate confirming marriage is still valid
• Income documentation meeting the 120% threshold
• Basic Korean language evidence (TOPIK Level 1 or KIIP Stage 2 completion)
• Criminal background check (범죄경력조회)
• Social Integration Program interview (brief conversational assessment)

F-6 Extension Is Not Mandatory After 2 Years

You are not required to apply for F-5 once you have been on F-6 for 2 years. F-6 extension continues to be available for as long as your qualifying condition holds. Many holders remain on F-6 indefinitely due to personal preferences, a planned return to their home country, or because they do not yet meet all F-5 requirements. The 2-year mark is the earliest eligibility point for F-5-2, not a deadline or mandatory transition.
