No person shall seek to have an H-2A worker, or other worker
employed in corresponding employment by an H-2A employer, waive rights
conferred under section 216 of the INA or under these regulations. Such
waiver is against public policy. Any agreement by an employee purporting
to waive or modify any rights inuring to said person under the Act or
these regulations shall be void as contrary to public policy, except
that a waiver or modification of rights or obligations hereunder in
favor of the Secretary shall be valid for purposes of enforcement of the
provisions of the Act or these regulations. This does not prevent
agreements to settle private litigation.
