The headquarters of which American organisation is in Langley, Virginia?

The Central Intelligence Agency (CIA) is a civilian foreign intelligence service of the United States federal government, tasked with gathering, processing, and analyzing national security information from around the world, primarily through the use of human intelligence (HUMINT). As one of the principal members of the U.S. Intelligence Community (IC), the CIA reports to the Director of National Intelligence and is primarily focused on providing intelligence for the President and Cabinet.

The CIA was formed on September 18, 1947 and their headquarters is at the George Bush Center for Intelligence, Langley, Virginia.

Unlike the Federal Bureau of Investigation (FBI), which is a domestic security service, the CIA has no law enforcement function and is mainly focused on overseas intelligence gathering, with only limited domestic intelligence collection.
