For foreign students aiming to enter a Korean graduate school (master's or doctoral program), the most critical first hurdle is the D-2-3 visa. Based on 2026 regulations, this guide covers everything in one place — visa sub-types, required documents, application procedures, permitted part-time work hours, and how to convert to the D-10 job-seeking visa after graduation.
Korean graduate schools offer world-class research environments, diverse financial support (BK21, GKS Government Scholarship for Foreigners), and a clear career pathway to employment in Korea — which is why the number of international applicants to STEM, business, international studies, and Korean studies master's programs grows every year. The D-2-3 visa is where that journey begins. Let's walk through it carefully.
D-2 Visa Sub-Types — Which Program Does D-2-3 Cover?
The D-2 visa (Study) is issued to foreign nationals enrolled in a regular degree program at a Korean higher education institution accredited by the Ministry of Education. Sub-types range from D-2-1 through D-2-8 by degree level — among them, D-2-3 covers master's programs and D-2-4 covers doctoral programs.
| Visa Type | Program | Duration |
|---|---|---|
| D-2-1 | Associate Degree (Junior College) | 2–3 years |
| D-2-2 | Bachelor's Degree (4-year University) | 4 years |
| D-2-3 ★ | Master's Degree (General & Professional Graduate School) | 2–3 years |
| D-2-4 | Doctoral Degree (General Graduate School) | 3–5 years |
| D-2-5 | Integrated Master's–Doctoral Program | 4–6 years |
| D-2-6 | Research Student | Research under faculty supervision |
D-2-3 covers not only general graduate schools but also professional graduate school master's programs — including law schools (로스쿨), medical graduate schools, MBA programs, and graduate schools of education. Online-only and evening-only programs are excluded from D-2 visa eligibility, so always confirm Ministry of Education accreditation before enrollment.
Eligibility Requirements — 4 Core Criteria
▶ ① Academic Qualification
You need at least a bachelor's degree to apply for a master's program. Graduates of a 4-year university in Korea or abroad — or those with an officially recognized equivalent qualification — are eligible. Some professional graduate schools (law schools, medical graduate schools, etc.) apply separate admission requirements, so check directly with the school's admissions office in advance.
▶ ② Official Admission Letter
A formal Admission Letter from a Ministry of Education-accredited graduate school is mandatory. It must state the degree level (master's), field of study, enrollment date, and required period of study. Conditional admission letters may require additional documents.
▶ ③ Proof of Financial Capacity
You must prove that you can cover tuition and living expenses. A bank balance certificate of ₩20 million or more (in your name or a supporting family member's name) is generally required, or it can be substituted by a scholarship or research grant award letter. GKS scholarship recipients may use their scholarship letter alone.
▶ ④ Health Requirement (TB High-Risk Countries)
Nationals from the 35 TB high-risk countries designated by the Ministry of Justice must submit a TB test certificate from a Korean embassy-designated hospital before entry. Check the list and designated hospitals at HiKorea (www.hikorea.go.kr).
Online cyber graduate schools and Korea National Open University graduate programs are excluded from D-2 visa eligibility. Always confirm that your program is an accredited in-person course before enrolling.

▶ Route B: Domestic Status-of-Residence Change (D-4 → D-2-3, etc.)
If you are lawfully staying in Korea on a language training visa (D-4) or similar, you can apply for a domestic status-of-residence change after being accepted by a graduate school — no departure required. Book your appointment at HiKorea (www.hikorea.go.kr) and submit at the local Immigration Office (출입국·외국인청). After the change is processed, confirm the update via HiKorea or by obtaining a Certificate of Alien Registration. ARC reissuance takes approximately 2–3 weeks.
Part-Time Work Hours — 2026 Updated Regulations
D-2-3 visa holders may legally work part-time after obtaining a part-time work permit (시간제취업허가). Working without this permit can lead to visa cancellation and deportation — always get authorized in advance.
| Korean Language Proficiency | During Semester (per week) | During Vacation |
|---|---|---|
| TOPIK Level 4 or above / English-track (IELTS 5.5+ or TOEFL iBT 71+) | 30 hrs | Unlimited |
| Below TOPIK Level 4 / expired TOPIK certificate | 15 hrs | 15 hrs (incl. weekends) |
The part-time work permit covers a maximum of 2 workplaces and is valid for up to 1 year within your permitted stay. Your TOPIK score is valid for 2 years from the date of issue — plan to retake it before it expires.
Converting to the D-10 Job-Seeking Visa After Graduation
After earning your master's degree from a Korean graduate school, if you want to find a job in Korea, you can convert to the D-10 job-seeking visa and continue job-search activities for up to 2 years. If you apply within 1 year of graduation, you are exempt from the points-based evaluation.
- Obtain graduation certificate
- Apply within 1 year of graduation (for points-exemption benefit)
- TOPIK Level 4 or above certificate recommended
- Obtain latest proof of financial capacity (within past 3 months)
- Apply via HiKorea online or visit your Immigration Office (출입국·외국인청)
Once you secure employment on a D-10, you can change to the E-7 (Designated Activities) visa or another employment-based residence status depending on occupation and salary.
