A federalapostille is a certificate issued by the U.S. Department of State that authenticates federal documents for use in foreign countries. It ensures that a document, such as an FBI background check or federal court ruling, is genuine and recognized by another country’s authorities. The apostille verifies the signature, seal, or stamp, confirming that the document is legitimate. This certification is part of the Hague Apostille Convention, which simplifies the process of international document recognition, allowing U.S. documents to be accepted without further legalization or embassy verification in countries that are part of the convention.
