29 CFR §501.9

1. (a)Notwithstanding the required bond amounts set forth in 20 CFR 655.132(c), the WHD Administrator may require that an H-2ALC obtain a bond with a higher face value amount after notice and opportunity for hearing when it is shown based on objective criteria that the amount of the bond is insufficient to meet potential liabilities.
2. (b)Upon a final decision reached pursuant to the administrative proceedings of subpart C of this part, including any timely appeal, or resulting from an enforcement action brought directly in a District Court of the United States finding a violation or violations of 20 CFR part 655, subpart B, or this part, the WHD Administrator may make a written demand on the surety for payment of any wages and benefits, including the assessment of interest, owed to an H-2A worker, a worker engaged in corresponding employment, or a U.S. worker improperly rejected or improperly laid off or displaced. The WHD Administrator shall have 3 years from the expiration of the labor certification, including any extension thereof, to make such written demand for payment on the surety. This 3-year period for making a demand on the surety is tolled by commencement of any enforcement action of the WHD Administrator pursuant to § 501.6, § 501.15, or § 501.16 or the commencement of any enforcement action in a District Court of the United States.
