Since 1967, the Freedom of Information Act (FOIA) has provided the public the right to request access to records from any federal agency. It is often described as the law that keeps citizens in the know about their government. Federal agencies are required to disclose any information requested under the FOIA unless it falls under one of nine exemptions which protect interests such as personal privacy, national security, and law enforcement.

Members of the public, including foreign citizens, military and civilian personnel acting as private citizens, organizations and businesses, and individual members of the Congress for themselves or constituents, may request records in writing. It is important to remember that the Freedom of Information Act applies only to federal agencies. It does not create a right of access to records held by Congress, the courts, state or local government agencies, or by private businesses or individuals. Each state has its own public access laws that should be consulted for access to state and local records.
