What is F-5-28?
F-5-28 is the permanent-residence (영주) upgrade for a 특별기여자 (special contributor) who already holds 거주(F-2) 카목 status — i.e. someone the Minister of Justice has recognized as having made a special contribution to the Republic of Korea, or contributed to the promotion of the public interest (per 출입국관리법 시행령 별표 1의3 제19호). The applicant must have held that F-2 카목 status and stayed continuously in Korea for at least 2 years. Site currently only covers the F-2 residence tier of this category (labeled F-2-16); F-5-28 is the separate, higher permanent-residence code the same person can move up to.
