Title 50 › Chapter CHAPTER 36— - FOREIGN INTELLIGENCE SURVEILLANCE › Subchapter SUBCHAPTER VI— - ADDITIONAL PROCEDURES REGARDING CERTAIN PERSONS OUTSIDE THE UNITED STATES › § 1881c
Allows the Foreign Intelligence Surveillance Court (FISC) to approve electronic or other intelligence collection that targets a United States person believed to be located outside the United States, but only under tight rules. No intelligence agency may intentionally target such a U.S. person when the person has a reasonable expectation of privacy and a warrant would be needed inside the United States, unless a FISC judge issues an order, the Attorney General approves an emergency action, or another specific law allows it. If the person is thought to be inside the United States while an order is active, the collection must stop unless the person is again believed to be outside. If the activity will occur inside the United States and could be done under section 1881b, it must follow that section or another applicable law. To get a FISC order, a federal officer must file a sworn written application that the Attorney General has approved. The application must include the applicant’s identity; the target’s identity or description; sworn facts saying the target is believed to be outside the United States and is a foreign power, an agent of a foreign power, or an officer or employee of a foreign power; rules for protecting private U.S. person information; a certification that the information sought is foreign intelligence and that getting that intelligence is a significant purpose; prior related applications; the requested time period (no more than 90 days per order); and certain disclosures about information that might show the application is wrong or that might be favorable to the target. A judge will issue an ex parte order only if there is probable cause for the target’s location and status, the protections for U.S. persons meet legal standards, and the application is complete and not clearly wrong. Orders last up to 90 days and can be renewed. The Attorney General may allow short emergency collections when delay would be harmful, but those end when the information is obtained, the court denies the application, or after 7 days. If an emergency or other collection is stopped and no order is issued, information from that collection generally cannot be used in court or disclosed, with narrow exceptions. The government can appeal denials to the FISC Court of Review and then seek Supreme Court review.
