Diploma Apostille for Thailand

Korean diplomas for use in Thailand require Overseas Koreans Agency (OKA) authentication and Thai Embassy legalization. This is needed for BOI work permit applications, professional licensing in Thailand, and employment with Thai companies requiring verified qualifications. Thailand has acceded to the Hague Apostille Convention, but it only enters into force on 2027-02-28; until then OKA authentication plus Thai Embassy legalization applies.

  1. 1Obtain the original diploma or certified copy from the Korean university
  2. 2Submit to OKA for authentication
  3. 3Submit to the Thai Embassy in Seoul for legalization
  4. 4Arrange a certified Thai translation if required
  5. 5Submit to the Thai employer, BOI, or professional licensing body
