20 CFR § 656.12 - Improper commerce and payment.
(a) Applications for permanent labor certification and approved labor certifications are not articles of commerce. They shall not be offered for sale, barter or purchase by individuals or entities. Any evidence that an application for permanent labor certification or an approved labor certification has been sold, bartered, or purchased shall be grounds for investigation under this part and may be grounds for denial under § 656.24, revocation under § 656.32, debarment under § 656.31(f), or any combination thereof.
(b) An employer must not seek or receive payment of any kind for any activity related to obtaining permanent labor certification, including payment of the employer's attorneys' fees, whether as an incentive or inducement to filing, or as a reimbursement for costs incurred in preparing or filing a permanent labor certification application, except when work to be performed by the alien in connection with the job opportunity would benefit or accrue to the person or entity making the payment, based on that person's or entity's established business relationship with the employer. An alien may pay his or her own costs in connection with a labor certification, including attorneys' fees for representation of the alien, except that where the same attorney represents both the alien and the employer, such costs shall be borne by the employer. For purposes of this paragraph (b), payment includes, but is not limited to, monetary payments; wage concessions, including deductions from wages, salary, or benefits; kickbacks, bribes, or tributes; in kind payments; and free labor.
(c) Evidence that an employer has sought or received payment from any source in connection with an application for permanent labor certification or an approved labor certification, except for a third party to whose benefit work to be performed in connection with the job opportunity would accrue, based on that person's or entity's established business relationship with the employer, shall be grounds for investigation under this part or any appropriate Government agency's procedures, and may be grounds for denial under § 656.32, revocation under § 656.32, debarment under § 656.31(f), or any combination thereof.
