The CIA's domestic field offices recruit foreigners living temporarily in the United States to work as agents for the CIA when they return home. They also conduct voluntary debriefings of Americans who have recently returned from abroad. The division also is responsible for handling some defectors and for limited counterintelligence targeting. The CIA's domestic division was created in 1963 to conduct clandestine operations within the United States against foreign targets, usually foreign spies and organizations. But the CIA no longer conducts clandestine operations at home, in part because of the 1973 intelligence overhaul that curbed spying on U.S. citizens and enacted stricter oversight of covert operations
