Is South Korea a Hague Convention country?
Yes. The Apostille Convention has been in force for South Korea since 14 July 2007, and for the United States since 15 October 1981 — so a U.S. apostille is accepted in South Korea with no embassy step.
The route to South Korea
A Naturalization Certificate is issued by US Citizenship and Immigration Services, a federal authority, so it is authenticated by the U.S. Department of State in Washington, D.C. — never by a state office. For South Korea, that apostille is the finish line.
People most often send documents to South Korea for teaching visas (E-2), employment, marriage. Receiving offices set their own requirements, so confirm what yours asks for — we’ll help you read it.
