Section 702 of the Foreign Intelligence Surveillance Act (50 U.S.C. § 1881a), enacted in 2008, authorizes the NSA, CIA, and FBI to compel U.S. telecommunications companies and internet providers to hand over communications of non-U.S. persons located outside the United States. The Foreign Intelligence Surveillance Court approves targeting procedures, minimization rules, and querying policies before collection begins. Unlike traditional wiretap warrants, Section 702 targets categories of foreign persons rather than named individuals, and it operates without probable cause requirements for each target.
The constitutional controversy centers on "incidental collection": when foreign targets communicate with Americans, those Americans'' messages enter government databases without a warrant, without individual suspicion, and without notice. The FBI can then query those databases using American names or identifiers — a practice called "backdoor search" — without obtaining a separate warrant. The NSA reported collecting over 250 million internet communications in a single year under Section 702. The FISA Court documented "persistent and widespread" FBI violations of Section 702 privacy restrictions in a 2022 opinion, including agents searching Americans'' data for reasons unrelated to national security.
Section 702 must be reauthorized by Congress periodically and has been renewed with limited reforms. Privacy advocates have argued since 2014 that FBI backdoor searches require a warrant under the Fourth Amendment. The intelligence community counters that warrant requirements would slow investigations and create inconsistency between national security and law enforcement cases. This disagreement has produced repeated reauthorization crises, including the April 2026 emergency extension.
Section 702 lets the government collect your messages without ever targeting you — because it targeted someone you communicated with. The FBI can then search those messages without a warrant. Every American who emails, calls, or messages someone overseas is potentially in Section 702 databases. Understanding the program tells you what Fourth Amendment rights you actually have versus what you think you have.
People often think Section 702 only collects foreigners' communications and doesn't affect Americans. In practice, whenever a foreign target communicates with an American, that American's side of the conversation enters government databases. The FBI can then search those databases using American names — without getting a warrant for the American.
