The CIA is an independent agency responsible for providing national security intelligence to senior US policymakers. The Director of the Central Intelligence Agency (D/CIA) is nominated by the president with the advice and consent of the Senate. The Director manages the operations, personnel, and budget of the Central Intelligence Agency.
The CIA is separated into four basic components: the National Clandestine Service, the Directorate of Intelligence, the Directorate of Science & Technology, and the Directorate of Support. They carry out “the intelligence cycle,” the process of collecting, analyzing, and disseminating intelligence information to top US government officials.
In addition, the D/CIA has several staffs that deal with public affairs, human resources, mission innovation, protocol, congressional affairs, legal issues, information management, and internal oversight.
