The Secretary of Homeland Security, in consultation with the Secretary of Labor, is exercising his time-limited Fiscal Year (FY) 2023 authority and increasing the total number of noncitizens who may receive an H-2B nonimmigrant visa by up to, but no more than, a total of 64,716 for the entirety of FY 2023. To assist U.S. businesses that need workers to begin work on different start dates, the Departments have decided to distribute the supplemental visas in several allocations, including two separate allocations for the second half of fiscal year 2023. Out of the total 64,716 visas made available in this rule, the Departments have decided to reserve 20,000 visas for nationals of Guatemala, El Salvador, Honduras, or Haiti. The Departments will make the 20,000 visas for nationals of Guatemala, El Salvador, Honduras, or Haiti available without regard to prior H-2B status, but the Departments will make the remainder of the supplemental visas available only to returning workers who were issued H-2B visas or held H-2B status in fiscal years 2020, 2021, or 2022. The Departments will make all 64,716 visas available only to those businesses that are suffering irreparable harm or will suffer impending irreparable harm, as attested by the employer on a new attestation form. In addition to making the additional 64,716 visas available under the FY 2023 time-limited authority, DHS is exercising its general H-2B regulatory authority to again provide temporary portability flexibility by allowing H-2B workers who are already in the United States to begin work immediately after an H-2B petition (supported by a valid temporary labor certification) is received by USCIS, and before it is approved.
