Apostille vs. Hague Convention: why a Korean degree doesn't need the same chain twice
Your diploma only needs an apostille if it was issued outside Korea by a Hague-member country. A Korean degree, or a document already inside Korea's system, follows no such chain at all because it's never leaving the country.

We get this message at least once a week: a teacher has already paid to notarize, apostille, and translate a diploma that never needed any of it. Usually it's someone who earned their degree in Korea, or who heard "apostille" and "legalize" used interchangeably online and decided to do both, just in case.
They're not the same thing, and mixing them up costs real money and weeks you don't have.
The Hague Apostille Convention is a treaty. Member countries agree to accept each other's apostille, a single certificate, as proof a document is genuine, instead of sending it through a multi-step embassy legalization chain. South Korea joined the Hague Convention on the Simplified Authentication of Documents on 25 October 2006, with the convention entering into force on 14 July 2007. An apostille is the certificate itself, issued by a specific government office in the country where your document was created.
So the question is never "do I need an apostille." It's "where was this document issued, and is that place a Hague member." Two answers matter for E-2 teachers:
If your degree was issued in the US, Canada, the UK, Ireland, Australia, New Zealand, or South Africa: you apostille it, full stop. All seven eligible countries are parties to the Hague Apostille Convention, so an apostille, not full consular legalisation, is what you need. One certificate from your country's designated authority, nothing from a Korean consulate.
This is where stale advice does damage. Canada joined the Hague Apostille Convention as of January 2024, which means anyone citing older guides written for Canadian teachers about embassy legalization is describing a process that no longer applies to them.
If your degree was issued in Korea: it needs neither an apostille nor legalization. The whole point of an apostille is to make one country's document legible to a different country's immigration office. A Korean-issued degree, used for a Korean government process, never crosses that line. Korean immigration already recognizes it as a domestic document. No certificate added on top makes it more valid.
| Where the degree was issued | What it needs |
|---|---|
| A Hague member (US, Canada, UK, Ireland, Australia, New Zealand, South Africa) | One apostille from that country's competent authority |
| Korea | Nothing added, no apostille, no legalization |
| A non-Hague country | A full consular legalization chain ending at a Korean mission |
This matters beyond E-2. Teachers moving onto F-2-7, F-4, F-5, or F-6 status sometimes hold degrees earned at Korean universities, often after years of residency. The instinct is to re-document everything the way they did for the original E-2, including a document that was Korean to begin with. The visa category and its document requirements are set by Korean immigration, not by the individual school, and that applies to F-series changes too. What counts as sufficient proof varies by office and by visa type, so confirm the specific list with immigration or your placement coordinator before you pay anyone to notarize something twice.
One thing that genuinely varies, and that we don't have a clean answer for: Korean immigration still prefers the physical paper apostille for E-2 visa documents, even though many Hague member states now issue digital e-Apostilles. Until that changes consistently across offices, request the paper version if you have a choice, and ask before assuming a digital one will be accepted.
Get the source of the document right first. Everything else, apostille or nothing, follows from that one fact.
