(a) The Administrator shall perform all the Secretary's investigative and enforcement functions under 8 U.S.C. 1182(m) and subparts L and M of this part.

(b) The Administrator, either because of a complaint or otherwise, shall conduct such investigations as may be appropriate and, in connection therewith, enter and inspect such places and such records (and make transcriptions thereof), question such persons and gather such information as deemed necessary by the Administrator to determine compliance with the matters to which a facility has attested under section 212(m) of the INA (8 U.S.C. 1182(m)) and subparts L and M of this part.

(c) A facility being investigated must make available to the Administrator such records, information, persons, and places as the Administrator deems appropriate to copy, transcribe, question, or inspect. A facility must fully cooperate with any official of the Department of Labor performing an investigation, inspection, or law enforcement function under 8 U.S.C. 1182(m) or subparts L or M of this part. Such cooperation shall include producing documentation upon request. The Administrator may deem the failure to cooperate to be a violation, and take such further actions as the Administrator considers appropriate.

(d) No facility may intimidate, threaten, restrain, coerce, blacklist, discharge, or in any manner discriminate against any person because such person has:

(1) Filed a complaint or appeal under or related to section 212(m) of the INA (8 U.S.C. 1182(m)) or subpart L or M of this part;

(2) Testified or is about to testify in any proceeding under or related to section 212(m) of the INA (8 U.S.C. 1182(m)) or subpart L or M of this part.

(3) Exercised or asserted on behalf of himself/herself or others any right or protection afforded by section 212(m) of the INA (8 U.S.C. 1182(m)) or subpart L or M of this part.

(4) Consulted with an employee of a legal assistance program or an attorney on matters related to the Act or to subparts L or M of this part or any other DOL regulation promulgated under 8 U.S.C. 1182(m).

(5) In the event of such intimidation or restraint as are described in this paragraph, the Administrator may deem the conduct to be a violation and take such further actions as the Administrator considers appropriate.

(e) A facility subject to subparts L and M of this part must maintain a separate file containing its Attestation and required documentation, and must make that file or copies thereof available to interested parties, as required by § 655.1150. In the event of a facility's failure to maintain the file, to provide access, or to provide copies, the Administrator may deem the conduct to be a violation and take such further actions as the Administrator considers appropriate.

(f) No facility may seek to have an H-1C nurse, or any other nurse similarly employed by the employer, or any other employee waive rights conferred under the Act or under subpart L or M of this part. In the event of such waiver, the Administrator may deem the conduct to be a violation and take such further actions as the Administrator considers appropriate. This prohibition of waivers does not prevent agreements to settle litigation among private parties, and a waiver or modification of rights or obligations in favor of the Secretary shall be valid for purposes of enforcement of the provisions of the Act or subpart L and M of this part.

(g) The Administrator shall, to the extent possible under existing law, protect the confidentiality of any complainant or other person who provides information to the Department.
