Why is apostille required on FBI background check documents internationally

The apostille on fbi background check is needed to validate FBI Identity History Summary reports for international use in countries that are part of the Hague Apostille Convention. Many countries require this document for visas residency employment or adoption purposes. Since the FBI background check is a federal document the apostille is issued by the U.S. Department of State rather than a state Secretary of State. This certification confirms the authenticity of signatures and seals making the document legally acceptable abroad without further legalization steps. Applicants use this process to ensure smooth immigration employment and legal verification across international jurisdictions worldwide.
