(1) Disclosed information to the employer, or to any other person, that the employee reasonably believes evidences a violation of sections 212(n) or (t) of the INA or any regulation relating to sections 212(n) or (t), including this subpart I and subpart H of this part and any pertinent regulations of DHS or the Department of Justice; or
(2) Cooperated or sought to cooperate in an investigation or other proceeding concerning the employer's compliance with the requirements of sections 212(n) or (t) of the INA or any regulation relating to sections 212(n) or (t).
(b) It shall be a violation of this section for any employer to engage in the conduct described in paragraph (a) of this section. Such conduct shall be subject to the penalties prescribed by sections 212(n)(2)(C)(ii) or (t)(3)(C)(ii) of the INA and § 655.810(b)(2), i.e., a fine of up to $9,380, disqualification from filing petitions under section 204 or section 214(c) of the INA for at least two years, and such further administrative remedies as the Administrator considers appropriate.
(c) Pursuant to sections 212(n)(2)(C)(v) and (t)(3)(C)(v) of the INA, an H–1B nonimmigrant who has filed a complaint alleging that an employer has discriminated against the employee in violation of paragraph (a)(1) of this section may be allowed to seek other appropriate employment in the United States, provided the employee is otherwise eligible to remain and work in the United States. Such employment may not exceed the maximum period of stay authorized for a nonimmigrant classified under sections 212(n) or (t) of the INA, as applicable. Further information concerning this provision should be sought from the United States Citizenship and Immigration Services of the Department of Homeland Security.
