Illinois Apostille for South Korea
Illinois documents authenticated for use in South Korea
In short: South Korea is a member of the Hague Apostille Convention, so an Illinois public document used there is authenticated with an apostille from the Illinois Secretary of State - not embassy legalization. We handle the whole process by mail. A certified Korean translation is usually required, which we can arrange.
What South Korea commonly needs apostilled
Illinois documents used in South Korea most often include birth and marriage certificates, university diplomas and transcripts, and powers of attorney - typically for residency, study, work, marriage, or business. South Korea is a member of the Hague Apostille Convention, so these Illinois public documents are authenticated with an apostille from the Illinois Secretary of State rather than embassy legalization. South Korea generally also requires a certified Korean translation, which we can coordinate.
