To obtain an apostille for a U.S. document, you must first identify the issuing state of the document. If it’s a state-issued document, like a birth certificate or marriage certificate, you’ll need to contact the Secretary of State’s office where it was issued. For federal documents, such as FBI background checks, the apostille is handled by the U.S. Department of State in Washington, D.C.
