50 U.S.C. § 1822 : US Code - Section 1822: Authorization of physical searches for foreign intelligence purposes

    (a) Presidential authorization
      (1) Notwithstanding any other provision of law, the President,
    acting through the Attorney General, may authorize physical
    searches without a court order under this subchapter to acquire
    foreign intelligence information for periods of up to one year if -
    
        (A) the Attorney General certifies in writing under oath that -
      
          (i) the physical search is solely directed at premises,
        information, material, or property used exclusively by, or
        under the open and exclusive control of, a foreign power or
        powers (as defined in section 1801(a)(1), (2), or (3) of this
        title);
          (ii) there is no substantial likelihood that the physical
        search will involve the premises, information, material, or
        property of a United States person; and
          (iii) the proposed minimization procedures with respect to
        such physical search meet the definition of minimization
        procedures under paragraphs (1) through (4) (!1) of section
        1821(4) of this title; and


        (B) the Attorney General reports such minimization procedures
      and any changes thereto to the Permanent Select Committee on
      Intelligence of the House of Representatives and the Select
      Committee on Intelligence of the Senate at least 30 days before
      their effective date, unless the Attorney General determines that
      immediate action is required and notifies the committees
      immediately of such minimization procedures and the reason for
      their becoming effective immediately.

      (2) A physical search authorized by this subsection may be
    conducted only in accordance with the certification and
    minimization procedures adopted by the Attorney General. The
    Attorney General shall assess compliance with such procedures and
    shall report such assessments to the Permanent Select Committee on
    Intelligence of the House of Representatives and the Select
    Committee on Intelligence of the Senate under the provisions of
    section 1826 of this title.
      (3) The Attorney General shall immediately transmit under seal to
    the Foreign Intelligence Surveillance Court a copy of the
    certification. Such certification shall be maintained under
    security measures established by the Chief Justice of the United
    States with the concurrence of the Attorney General, in
    consultation with the Director of National Intelligence, and shall
    remain sealed unless - 
        (A) an application for a court order with respect to the
      physical search is made under section 1821(4) of this title and
      section 1823 of this title; or
        (B) the certification is necessary to determine the legality of
      the physical search under section 1825(g) of this title.

      (4)(A) With respect to physical searches authorized by this
    subsection, the Attorney General may direct a specified landlord,
    custodian, or other specified person to - 
        (i) furnish all information, facilities, or assistance
      necessary to accomplish the physical search in such a manner as
      will protect its secrecy and produce a minimum of interference
      with the services that such landlord, custodian, or other person
      is providing the target of the physical search; and
        (ii) maintain under security procedures approved by the
      Attorney General and the Director of National Intelligence any
      records concerning the search or the aid furnished that such
      person wishes to retain.

      (B) The Government shall compensate, at the prevailing rate, such
    landlord, custodian, or other person for furnishing such aid.
    (b) Application for order; authorization
      Applications for a court order under this subchapter are
    authorized if the President has, by written authorization,
    empowered the Attorney General to approve applications to the
    Foreign Intelligence Surveillance Court. Notwithstanding any other
    provision of law, a judge of the court to whom application is made
    may grant an order in accordance with section 1824 of this title
    approving a physical search in the United States of the premises,
    property, information, or material of a foreign power or an agent
    of a foreign power for the purpose of collecting foreign
    intelligence information.
    (c) Jurisdiction of Foreign Intelligence Surveillance Court
      The Foreign Intelligence Surveillance Court shall have
    jurisdiction to hear applications for and grant orders approving a
    physical search for the purpose of obtaining foreign intelligence
    information anywhere within the United States under the procedures
    set forth in this subchapter, except that no judge (except when
    sitting en banc) shall hear the same application which has been
    denied previously by another judge designated under section 1803(a)
    of this title. If any judge so designated denies an application for
    an order authorizing a physical search under this subchapter, such
    judge shall provide immediately for the record a written statement
    of each reason for such decision and, on motion of the United
    States, the record shall be transmitted, under seal, to the court
    of review established under section 1803(b) of this title.
    (d) Court of review; record; transmittal to Supreme Court
      The court of review established under section 1803(b) of this
    title shall have jurisdiction to review the denial of any
    application made under this subchapter. If such court determines
    that the application was properly denied, the court shall
    immediately provide for the record a written statement of each
    reason for its decision and, on petition of the United States for a
    writ of certiorari, the record shall be transmitted under seal to
    the Supreme Court, which shall have jurisdiction to review such
    decision.
    (e) Expeditious conduct of proceedings; security measures for
      maintenance of records
      Judicial proceedings under this subchapter shall be concluded as
    expeditiously as possible. The record of proceedings under this
    subchapter, including applications made and orders granted, shall
    be maintained under security measures established by the Chief
    Justice of the United States in consultation with the Attorney
    General and the Director of National Intelligence.
