20 C.F.R. § 655.72 – Revocation.

(a) Basis for DOL revocation. The Administrator, OFLC may revoke a temporary labor certification approved under this subpart, if the Administrator, OFLC finds:
1. (1) The issuance of the temporary labor certification was not justified due to fraud or willful misrepresentation of a material fact in the application process, as defined in § 655.73(d);
2. (2) The employer substantially failed to comply with any of the terms or conditions of the approved temporary labor certification. A substantial failure is a willful failure to comply that constitutes a significant deviation from the terms and conditions of the approved certification and is further defined in § 655.73(d) and (e);
3. (3) The employer failed to cooperate with a DOL investigation or with a DOL official performing an investigation, inspection, audit (under § 655.73), or law enforcement function under 29 CFR part 503 or this subpart; or
4. (4) The employer failed to comply with one or more sanctions or remedies imposed by WHD, or with one or more decisions or orders of the Secretary with the respect to the H-2B program.
(b) DOL procedures for revocation—(1) Notice of Revocation. If the Administrator, OFLC makes a determination to revoke an employer's temporary labor certification, the Administrator, OFLC will send to the employer (and its attorney or agent, if applicable) a Notice of Revocation. The notice will contain a detailed statement of the grounds for the revocation and inform the employer of its right to submit rebuttal evidence or to appeal. If the employer does not file rebuttal evidence or an appeal within 10 business days from the date the Notice of Revocation is issued, the notice is the final agency action and will take effect immediately at the end of the 10-day period.
(2) Rebuttal. If the employer timely submits rebuttal evidence, the Administrator, OFLC will inform the employer of the final determination on the revocation within 10 business days of receiving the rebuttal evidence. If the Administrator, OFLC determines that the certification should be revoked, the Administrator, OFLC will inform the employer of its right to appeal according to the procedures of § 655.61. If the employer does not appeal the final determination, it will become the final agency action.
(3) Appeal. An employer may appeal a Notice of Revocation, or a final determination of the Administrator, OFLC after the review of rebuttal evidence, according to the appeal procedures of § 655.61. The ALJ's decision is the final agency action.
(4) Stay. The timely filing of rebuttal evidence or an administrative appeal will stay the revocation pending the outcome of those proceedings.
(5) Decision. If the temporary labor certification is revoked, the Administrator, OFLC will send a copy of the final agency action to DHS and the Department of State.
(c) Employer's obligations in the event of revocation. If an employer's temporary labor certification is revoked, the employer is responsible for:
(1) Reimbursement of actual inbound transportation and other expenses;
(2) The workers' outbound transportation expenses;
(3) Payment to the workers of the amount due under the three-fourths guarantee; and
(4) Any other wages, benefits, and working conditions due or owing to the workers under this subpart.
