Title 50 › CHAPTER 44 — NATIONAL SECURITY › SUBCHAPTER I — COORDINATION FOR NATIONAL SECURITY › § 3039
Intelligence agencies may, when a United States law enforcement agency asks, collect information outside the United States about people who are not United States persons. They may do this even if the law enforcement agency plans to use the information for a law enforcement or counterintelligence investigation. For the Department of Defense, only four agencies may help: the National Security Agency, the National Reconnaissance Office, the National Geospatial-Intelligence Agency, and the Defense Intelligence Agency. DoD help cannot include an Army, Navy, Air Force, or Marine Corps member directly taking part in an arrest or similar action. Help cannot be given if it would hurt military readiness. The Secretary of Defense must create rules for how DoD agencies use this authority and protect sources and methods. The Attorney General names which federal departments count as a United States law enforcement agency. "United States person" means (A) a U.S. citizen, (B) a known permanent resident alien, (C) an unincorporated group mostly made up of U.S. citizens or permanent residents, and (D) a corporation incorporated in the United States unless it is directed and controlled by a foreign government.
