The Foreign Intelligence Surveillance Act of 1978 is a United States federal law which establishes procedures for the physical and electronic surveillance and collection of "foreign intelligence information" between "foreign powers" and "agents of foreign powers" suspected of espionage or terrorism. The Act created the Foreign Intelligence Surveillance Court (FISC) to oversee requests for surveillance warrants by federal law enforcement and intelligence agencies. It has been repeatedly amended since the September 11 attacks.
