Apostilled FBI Check
US Citizens must now provide an FBI level check in order to obtain a visa to teach in Korea. Since the FBI check takes up to 12 weeks( but it usually takes around 5~7 weeks), applicants should apply for it and obtain the FBI-level check as early as possible in the process.
FBI Check application:

IMPORTANT: When sending in the application for FBI check, make sure to include a separate note stating: "Please provide an FBI seal and signature from a Division Officer for the purpose of obtaining a Federal Apostille."
(You will need to make sure this is done as the FBI check needs this signature on it in order for you to be able to get an Apostille, which is the next step. It must be requested specifically and can just be written on a piece of paper and included in the application.)
After you receive your FBI check, you have to get it apostilled.
You can get apostille from Office of the Secretary of state
(Apostille: http://www.apostilleinfo.com/usa.htm ) but lots of Office of the Secretary of state don¡¯t do apostille certificate to document issued by Federal government so please check it out with them and if they don¡¯t do , please get it apostille from The Department of State, Authentications Office in Washington DC.( See below information)
