D-2 Student Visa Requirements for Vietnamese Applicants to Korean Universities
By Muntasir • Published Sep 18, 2026 • Updated Sep 18, 2026 • Visas & Student Mobility, Study in Southeast Asia
The D-2 visa is for Vietnamese students admitted to a full Korean degree programme, separate from the D-4 visa for pre-degree Korean language study. Korea lowered its financial proof requirement in June 2023, but still reviews Vietnamese applications closely given how many Vietnamese students apply each year.
📩 You need a certificate of admission, notarized academic records, and proof of funds
💵 Since June 2023 the bank balance requirement is KRW 20 million in major cities, KRW 16 million outside them
🏠 Vietnam is Korea's largest single source of international students
⏱️ Apply at the Korean Embassy in Hanoi or a Consulate General once your certificate of admission arrives
D-2 vs D-4: Pick the Right Visa
Korea issues 2 separate student visas. D-2 covers admission into a full degree programme: associate, bachelor's, master's, or doctoral. D-4 covers a Korean language institute, the route many students use to build Korean before applying to a degree. If you already hold a certificate of admission to a degree programme, apply for D-2 directly. If you plan to study Korean first, apply for D-4 and convert to D-2 once a degree programme admits you.
| D-2 | D-4 | |
|---|---|---|
| Purpose | Full degree programme | Korean language institute, no degree yet |
| Who applies | Students with a certificate of admission to a degree | Students planning to build Korean before a degree |
| Next step | Study directly toward your degree | Convert to D-2 once admitted to a degree programme |
Documents You Need
Passport valid for your full study period
Completed visa application form and photo
Certificate of admission from your Korean university, in the standard format Korea requires for international student visas
Academic transcripts and diploma, notarized and, if the consulate requests it, apostilled
Proof of funds: a bank balance certificate showing you or your sponsor holds the required amount
Proof of relationship if a family member sponsors your finances
Health documents, if the consulate requests them
How Much Money You Need to Show
Korea lowered its D-2 financial proof requirement in June 2023 as part of a wider push to grow international enrollment. The required bank balance dropped from KRW 26 million (about USD 20,000) to KRW 20 million (about USD 15,000) for schools in major cities, and to KRW 16 million (about USD 12,000) for schools outside major cities, according to ICEF Monitor . You typically need to hold this balance in your own or your sponsor's account for a set period before applying, since immigration reviews the account history rather than the balance on the day you apply alone.
Why Your File Gets Extra Review
Vietnam sends more international students to Korea than any other country. As of August 2025, Vietnamese students made up over a third of Korea's entire international student population, ahead of China, according to ICEF Monitor . That scale means Korean consulates in Vietnam process a high volume of D-2 and D-4 applications and check documents closely for consistency: does your bank balance match your family's declared income, does your intended major match your prior study, does your Korean level match the programme you're entering. Weak links in that chain, more than any single rule aimed at Vietnamese applicants alone, drive most requests for extra documents or refusals.
Where to Apply
Apply at the Korean Embassy in Hanoi or the Korean Consulate General covering your province, in Ho Chi Minh City or Danang depending on where you live. Processing time varies by consulate and season, so apply as soon as you hold your certificate of admission rather than close to your intake date. Some consulates call selected applicants in for an interview, mainly to confirm your study plan and financial documents in person. Book your appointment as early as the consulate allows, since slots fill up fastest in the months before Korea's March and September intakes.
If you use an education agent to prepare your file, check their track record with Korean university admissions specifically, not general study-abroad experience. A well prepared, consistent file from a reputable agent moves through consulate review faster than a rushed one, even when the underlying qualifications are the same.
If Your Application Comes Back With Questions
A consulate that asks for more documents is not the same as a refusal. Common follow-up requests include a longer bank statement history, a clearer explanation of how a sponsor's income supports your fees and living costs, or extra evidence that your intended major connects to your prior study. Respond fully and promptly rather than resubmitting the same file with one document added, since a partial response often triggers another round of questions.
If your application is refused outright, ask the consulate for the stated reason before you reapply. Reapplying with the same weak point unaddressed, most often a financial gap or an unclear study plan, produces the same result a second time.
After You Arrive
Register your alien registration card within 90 days of arrival and keep your class attendance up. Korean universities report low attendance and dropouts to immigration, and a poor record affects your visa renewal and any future family visa sponsorship. Build your part-time work schedule, if you take one, around your class hours rather than the other way round, since attendance problems carry more weight with immigration than most students expect.
Before You Apply
Confirm your certificate of admission uses Korea's standard format before submitting your visa file.
Open or top up your bank account well ahead of your application, since immigration checks account history, not only the closing balance.
Line up notarized copies of every transcript and diploma before you book your consulate appointment.
Bring a clear, honest study plan to any interview, tied to your actual academic background.
