Residence Status and Visa Applications →

01
Check the detailed status: First decide whether it is Korean language training at a university-affiliated language institute (D-4-1) or foreign language training (D-4-7). The detailed status and required documents differ by training institution.
02
Obtain the standard letter of admission: Apply to the language institute, pay the tuition, and receive the standard letter of admission. The training period and course name on the letter must match the visa application documents.
03
Prepare education and financial documents: Prepare the certificate of final education with an apostille or consular confirmation, and prove financial ability with a bank balance maintained for a certain period or a deposit certificate. If parents or others bear the costs, submit family relationship documents and a statement of financial support together.
04
Visa application or change in Korea: Applicants abroad apply for a visa at a Korean diplomatic mission, and those staying in Korea apply to the immigration office having jurisdiction over their place of stay for permission to change status when they meet the requirements.
05
Alien registration after entry: Complete alien registration at the immigration office having jurisdiction over your place of stay within 90 days from the date of entry. If you move, report it within 15 days from the date of moving in.
06
Attendance management and extension: The extension review looks at attendance, grades and tuition payment records, so keep attendance certificates each term and apply for extension before expiry. Part-time work is allowed only after obtaining permission for activities outside the status of stay.
