Republic of Korea
South Korea's immigration is administered by the Korea Immigration Service under the Ministry of Justice. The system uses letter-coded visa categories: E-series for employment (E-7 designated activities, E-2 teaching), D-series for study and investment (D-8 corporate investment, D-10 job-seeking), and F-series for residence (F-2 points-based, F-5 permanent residence). Korea introduced a points-based F-2-7 system to attract skilled foreign professionals.
