The Act created the Foreign Intelligence Surveillance Court (FISC) and enabled it to oversee requests for surveillance warrants by federal law enforcement and intelligence agencies (primarily the Federal Bureau of Investigation and the National Security Agency) against suspected foreign intelligence agents inside the U.S. The court is located within the E. Barrett Prettyman United States Courthouse in Washington, D.C. The court is staffed by eleven judges appointed by the Chief Justice of the United States to serve seven-year terms.
