Summary  
This document details the case of Yurily Ivanovich Nosenko, a Soviet KGB officer who defected in 1964 and was involuntarily confined in the United States by U.S. intelligence agencies. Nosenko first contacted U.S. authorities via a contact in Switzerland in June 1962 and again in January 1964. After being brought to the U.S., he was confined at an Agency-controlled site in Clinton, Maryland, starting August 1965. He was later transferred to Camp Peary, Virginia, and returned to the Washington area by October 1967. Nosenko became a U.S. citizen in April 1974 and continued working under contract for the Agency until at least 1967, with an annual salary of $25,000. Legal discussions regarding his confinement occurred in April 1964, involving the Deputy Attorney General and the Director of Security, who concluded that his detention was justified. A memorandum dated 2 October 1968 summarized the case, confirming Nosenko’s status as a bona fide defector, though a draft memorandum later questioned this assessment. The Agency maintained files on Nosenko in specific locations, with contact details provided for relevant offices.
