There are multiple F-2 sub-categories: spouses of Korean nationals (in conjunction with F-6), long-term residents who have held legal status for 5+ years, qualified overseas Koreans, recipients of the Korea Immigration and Integration Program (KIIP), and point-based system qualifiers (F-2-7). F-2-99 (기타 장기체류) is available to foreign nationals in professional/skilled/investment/trade visa categories (E-1–E-7, D-5–D-9, D-2, etc.) who have continuously stayed 5+ years, maintain stable housing, meet a financial self-sufficiency test, and demonstrate basic Korean language/culture aptitude. As of September 2025, accompanying family members (spouse and minor children) of F-2-99 holders can also obtain F-2-99 status once they individually meet the residence period and basic aptitude requirements.
