Title 50 › Chapter 36— FOREIGN INTELLIGENCE SURVEILLANCE › Subchapter VI— ADDITIONAL PROCEDURES REGARDING CERTAIN PERSONS OUTSIDE THE UNITED STATES › § 1881c
Federal intelligence agencies must get approval from a special court before they can deliberately collect foreign intelligence by targeting a United States person who is believed to be outside the United States and who would have a reasonable expectation of privacy that would require a warrant if the same search happened inside the U.S. A judge of the Foreign Intelligence Surveillance Court must sign the order, or the Attorney General can allow a short emergency collection, or another part of the law can apply. If the person comes to be believed to be inside the United States while an order is in effect, the collection must stop unless the person is again believed to be outside. Collections done inside the United States that could be handled under another law must use that law instead. A federal officer must apply in writing and the Attorney General must approve before the court will act. The application must include things like who is applying, who the target is or a description of them, sworn facts showing the target is believed to be outside the U.S. and linked to a foreign power, rules to limit how information about U.S. persons is handled, a certification that the information sought is foreign intelligence and that getting that intelligence is a significant purpose, any prior related applications, and a requested time period not longer than 90 days. The court will privately grant the order only if it finds probable cause for the outside location and foreign-power connection, the minimization rules are adequate, and the application meets all requirements. Orders last up to 90 days and can be renewed. In emergencies the Attorney General can authorize collection for up to 7 days unless the information is obtained sooner or a court order is denied. If an emergency collection ends without a court order, the information generally cannot be used in legal proceedings or shared, except if the target is later found not to be a U.S. person or the Attorney General allows sharing because the information shows a risk of death or serious harm. The government can appeal decisions to a review court and then to the Supreme Court.
