It specifically states that it can't be used against a US Citizen and it also has to be run by the Attorney General

a)(1) Notwithstanding any other law, the President, through the
Attorney General, may authorize electronic surveillance without a
court order under this subchapter to acquire foreign intelligence
information for periods of up to one year if the Attorney General
certifies in writing under oath that -
(A) the electronic surveillance is solely directed at -
(i) the acquisition of the contents of communications
transmitted by means of communications used exclusively between
or among foreign powers, as defined in section 1801(a)(1), (2),
or (3) of this title; or
(ii) the acquisition of technical intelligence, other than
the spoken communications of individuals, from property or
premises under the open and exclusive control of a foreign
power, as defined in section 1801(a)(1), (2), or (3) of this
title;

(B) there is no substantial likelihood that the surveillance
will acquire the contents of any communication to which a United
States person is a party; and
(C) the proposed minimization procedures with respect to such
surveillance meet the definition of minimization procedures under
section 1801(h) of this title; and

if the Attorney General reports such minimization procedures and
any changes thereto to the House Permanent Select Committee on
Intelligence and the Senate Select Committee on Intelligence at
least thirty days prior to their effective date, unless the
Attorney General determines immediate action is required and
notifies the committees immediately of such minimization procedures
and the reason for their becoming effective immediately.
(2) An electronic surveillance authorized by this subsection may
be conducted only in accordance with the Attorney General's
certification and the minimization procedures adopted by him. The
Attorney General shall assess compliance with such procedures and
shall report such assessments to the House Permanent Select
Committee on Intelligence and the Senate Select Committee on
Intelligence under the provisions of section 1808(a) of this title.
(3) The Attorney General shall immediately transmit under seal to
the court established under section 1803(a) of this title a copy of
his certification. Such certification shall be maintained under
security measures established by the Chief Justice with the
concurrence of the Attorney General, in consultation with the
Director of Central Intelligence, and shall remain sealed unless -
(A) an application for a court order with respect to the
surveillance is made under sections 1801(h)(4) and 1804 of this
title; or
(B) the certification is necessary to determine the legality of
the surveillance under section 1806(f) of this title.

(4) With respect to electronic surveillance authorized by this
subsection, the Attorney General may direct a specified
communication common carrier to -
(A) furnish all information, facilities, or technical
assistance necessary to accomplish the electronic surveillance in
such a manner as will protect its secrecy and produce a minimum
of interference with the services that such carrier is providing
its customers; and
(B) maintain under security procedures approved by the Attorney
General and the Director of Central Intelligence any records
concerning the surveillance or the aid furnished which such
carrier wishes to retain.

The Government shall compensate, at the prevailing rate, such
carrier for furnishing such aid.
(b) 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 court
having jurisdiction under section 1803 of this title, and a judge
to whom an application is made may, notwithstanding any other law,
grant an order, in conformity with section 1805 of this title,
approving electronic surveillance of a foreign power or an agent of
a foreign power for the purpose of obtaining foreign intelligence
information, except that the court shall not have jurisdiction to
grant any order approving electronic surveillance directed solely
as described in paragraph (1)(A) of subsection (a) of this section
unless such surveillance may involve the acquisition of
communications of any United States person.
