F-5 — permanent residence

What F-5 gives you

• Indefinite right to remain. No status expiry, though the card is renewed every ten years.
• Unrestricted work and business activity.
• Freedom from re-entry permit requirements for ordinary travel.
• Local voting rights after a qualifying period of residence.
• Protection from the sponsorship cliff — losing your job no longer threatens your status.

What it does not give you: a Korean passport, national voting rights, or eligibility for public office. Those require naturalisation, which is a separate process with its own tests and, for most applicants, renunciation of the previous nationality.

The sub-categories that matter

F-5 is split into sixteen numbered routes. Most foreign residents will qualify, if at all, under one of these:

The variation between routes is large — residence periods, income multiples and language thresholds all differ. Identify your route first, then read that route's requirements. Advice written about F-5-1 is actively misleading if you are on the F-5-2 track.

The common requirements

Continuous residence

The general route requires five years of continuous lawful residence on an eligible status. Two things routinely go wrong:

• Not all time counts. D-4 language study and H-1 working holiday time generally do not. D-2 study time is treated more generously in some routes than others.
• Long absences break continuity. Extended periods outside Korea can reset the clock. If you are planning a long trip home in year four, check first.

Income and assets

The general route (F-5-1) requires income of twice GNI per capita, assessed on your own income rather than the household's. Against the Bank of Korea's 2025 figure of ₩52,570,000, that is about ₩105,000,000. Assets can substitute or supplement in some categories — the general route accepts net assets of 1.5 times the average Korean household's. Overseas-Korean routes apply a single multiple rather than double, and a 2026 reform relaxed the income test for applicants with strong Korean ability or a volunteering record.

Because the benchmark moves annually, so does the figure — and immigration offices update their operative GNI number around April, so it can lag the newest Bank of Korea release by months. Practice sources in early 2026 were still quoting ₩104,830,000. Confirm the figure in force on your filing date with your office or on 1345; theirs is the one that counts.

Language and social integration

Satisfied by completing the Social Integration Program (KIIP) or passing the Korea Immigration & Integration Test. KIIP is free, runs in every region, and is the route almost everyone takes because it also counts towards naturalisation later.

Clean record

Criminal record and tax clearance certificates, at both national and local level. Tax arrears are a common and entirely avoidable cause of refusal — pull your 납세증명서 months in advance, not the week before.

The realistic route for most people

For a foreign professional with no Korean family, the standard sequence is:

D-2 or D-10 → E-7 → F-2-7 → F-5

Each step typically takes two to three years, so eight to ten years from arrival to permanent residence is normal. The F-2-7 step is the important one: it removes sponsorship risk, and time held on F-2 feeds directly into the F-5 residence requirement.

For a spouse of a Korean national the sequence is far shorter — F-6 → F-5-2 — which is why the two situations should never be described with the same timeline.

Keeping it

F-5 does not expire, but it can be revoked. The realistic risks are a serious criminal conviction and a very long absence from Korea without a re-entry arrangement. The residence card itself is renewed every ten years; missing that renewal is an administrative violation, not a loss of status, but it carries a fine.
