D-2-3 (Master's Degree Student) Korea Visa Guide | 2026
D-2-3 (석사과정) is the study visa for a MASTER'S degree course. It is easily confused with D-2-5, which is the research course (연구과정) — a different code for a different purpose.
D-2-3 is a long-stay student status for enrolment on a master's degree course at an eligible Korean institution. Within the manual's D-2 code table it sits between D-2-2, the bachelor's course, and D-2-4, the doctoral course.
2. Eligibility Checklist
Admitted to a master's degree course. Doctoral study is D-2-4; a research course that is not a degree programme is D-2-5.
New admission: can produce a BACHELOR'S graduation certificate — the manual requires proof of the level below the one you are entering.
Holds a standard admission letter (표준입학허가서) issued by the university's president or dean.
Can evidence funding for tuition and living costs; where a parent's bank balance is used, family relationship documents are required too.
The institution is not one of the excluded types — distance universities, lifelong-education institutions, polytechnic vocational courses, or unapproved night programmes. Night graduate schools are recognised only where no daytime equivalent exists and the course has passed prior review.
