Apostille or Consular Confirmation? Getting Your Documents Ready for a Korean Student Visa
7 min read

The essay gets the attention. The recommendation letter gets rewritten four times. And then an application gets rejected because a graduation certificate arrived without the one stamp that tells Korea "this is real."
That stamp is either an apostille or a consular confirmation, and which one you need depends entirely on where the document was issued. Get it wrong, or leave it too late, and it is the single most common way a strong GKS or D-2 application misses its own deadline — not the essay, the paperwork behind it.

Which one do you need?
The question isn't which is "better" — it's which country issued the document.
If your country signed the Hague Apostille Convention, an apostille from your own government — usually the foreign ministry, courts, or education ministry — is enough on its own. Korea has recognized apostilles since July 14, 2007, when its own accession took effect. If your country never joined, the document instead needs consular confirmation: physically taken to (or mailed to) the Korean embassy or consulate with jurisdiction over where it was issued.
What actually needs the stamp
For any Korean study visa — GKS or a direct D-2 application through a university — the documents that typically need apostille or consular confirmation are the ones proving who you are and what you've already completed: your graduation certificate or diploma, your transcript, and — for scholarship applicants specifically — the nationality and family-relationship certificates that prove you and your parents hold foreign nationality. Korea's Ministry of Foreign Affairs runs a free online e-Apostille service (apostille.go.kr) for Korean-issued documents; for documents issued abroad, you're working with your own country's process instead.
GKS specifically: two rounds, two different rulebooks
If you're applying through the Global Korea Scholarship, the document rules actually change partway through your own application.
First round
Reviewed by the embassy or university you're applying through. They set their own rules on what counts — a scanned copy is often fine here.
Second and third round
Reviewed by NIIED, the national scholarship office. Apostille or consular confirmation is required, originals only, and nothing submitted is ever returned.
Two details from the official 2026 guidelines that quietly end applications every cycle: your English name must match your passport exactly, middle name included — a mismatch between your application and your visa issuance certificate is a documented cause of visa delays. And once you clear the first round, gather everything to NIIED's stricter standard immediately, rather than waiting to be asked — apostilled or consular-confirmed documents are valid for two years from issue unless the document itself states otherwise, but getting one takes weeks, and GKS deadlines don't move for anyone.
What's changing for Vietnam
Vietnam is one of the largest single sources of international students in Korea, and until now, every Vietnamese-issued diploma or family certificate headed for a Korean university or GKS application has needed consular confirmation — a trip to the Korean Embassy in Hanoi or the Consulate General in Ho Chi Minh City, on top of whatever Vietnam's own ministries had already certified. From September 11, 2026, that step disappears: a document apostilled by Vietnam's own government will be accepted in Korea the same way a document from any other member country already is.
If your application timeline straddles that date, it's worth checking which route is actually faster for you right now rather than assuming the old process still applies — and confirming with your embassy or university that they've updated their own checklist, since institutional guidance can lag an international treaty by a few weeks.
Soo, what?
None of this shows up in a university's marketing brochure, and it's rarely the first thing an international office mentions at orientation — by the time it comes up, someone has usually already missed a submission window waiting on a document that takes three weeks to process. It's also a recurring thread on expat forums for Korea, which tend to catch the problem only after it's already cost someone a semester. Soo House — the platform connecting foreign residents in Korea to campaigns, classes and each other — runs exactly the kind of settlement-focused community events, like Seoul Global Center's Welcoming Week sessions, where this is the question that actually gets asked out loud: not "is Korea hard to move to," but "why didn't anyone tell me my transcript needed a stamp from my own government before it needed one from Korea's."
Where to check
- apostille.go.kr — Korea's own e-Apostille service, and the country list it checks documents against
- studyinkorea.go.kr — NIIED's official GKS guidelines, including the exact document checklist for your cycle
- Your local Korean embassy or consulate — for consular confirmation, or to confirm whether your country's apostille status has changed
- 1345 — the immigration contact centre, interpretation available
Every Korean visa built on foreign-issued paperwork — a study visa, a work visa, even a marriage certificate for a family visa — runs through some version of this same authentication step. It's one of the few parts of moving to Korea that a foreign resident can fully finish before ever boarding a flight, and one of the few genuine advantages of starting early rather than starting under pressure.
Your Next Hop: before you request a single certificate, check apostille.go.kr for your country's current status — not last year's, this year's — so you know from day one which of the two paths in this guide you're actually on.
Checked in August 2026 against the Global Korea Scholarship's 2026 Undergraduate Application Guidelines (NIIED), Korea's Ministry of Foreign Affairs apostille service (apostille.go.kr), and the Hague Conference on Private International Law's own status table for the Apostille Convention, including Vietnam's accession record. Apostille Convention membership changes over time — confirm your own country's current status before relying on any date in this guide.
