Title 50 › Chapter CHAPTER 36— - FOREIGN INTELLIGENCE SURVEILLANCE › Subchapter SUBCHAPTER II— - PHYSICAL SEARCHES › § 1824
A judge must approve a requested physical search without the target present if four things are true: a federal officer made the request and the Attorney General approved it; there is probable cause (a strong reason to believe) that the target is a foreign power or an agent of a foreign power and that the place or property is or will be used by, owned by, or in transit to or from that target (a U.S. person cannot be called an agent just for First Amendment activities); the proposed minimization procedures meet the subchapter’s standards; and the application includes all required statements and certifications (and, for a U.S. person target, those certifications are not clearly wrong based on the filed statements). The judge can look at past, present, or planned activities when deciding probable cause. An approved order must say who or what is targeted (if known), where to search, what may be seized or copied, how each search will be done and which minimization rules apply, and how long the searches are allowed. The order must require following the minimization steps, let specified landlords or custodians give secret help and information, require them to keep records under approved security, pay them at the prevailing rate, and require the federal officer to report the search results to the court. Normal approval lasts only as long as needed or 90 days, whichever is shorter, except searches against a foreign power or against a non‑U.S.‑person agent may last up to the time requested or one year, whichever is shorter. The judge may later check whether minimization rules were followed. The Attorney General can authorize an emergency search if there is an urgent need and a factual basis; the AG must notify a Foreign Intelligence Surveillance Court judge and apply for approval within 7 days, and minimization rules must be followed. If no court order is issued, any information from the search generally cannot be used in legal or official proceedings and U.S. person information cannot be shared without consent, except with AG approval when there is a threat of death or serious bodily harm. The AG must check compliance with these limits. Applications and orders must be kept for at least 10 years.
