An apostille for an FBI background report is a form of authentication issued by the U.S. Department of State, certifying the authenticity of an FBI background check for use in other countries. This document is essential for many purposes such as work visas, immigration, and international legal proceedings. Without an apostille, your FBI background check may not be acknowledged abroad. Double check to ensure that the requestor doesn’t need an FBI issued within X timeframe before submitting an older version of an FBI Criminal Background Check. An FBI background check is a comprehensive review of an individual’s identity and criminal history, compiled from federal, state, and local law enforcement databases. It’s often required for jobs with the federal government, certain private sector positions, or for obtaining a security clearance or license. The check typically involves submitting fingerprints for comparison against the FBI’s national fingerprint database (IAFIS).
