On October 8, 2020, the U.S. Department of Labor (DOL) published its long-speculated interim final rule, “Strengthening Wage Protections for the Temporary and Permanent Employment of Certain Aliens in the United States.” The new rule will update how the existing “four-tiered wage structure based on the Occupational Employment Statistics (OES) wage survey” is calculated for purposes of determining prevailing wages. The rule goes into effect immediately on October 8, 2020, with no notice period. These changes will result in significant wage increases to the wage levels for all four levels of the OES survey, across all occupations. The wage adjustments will affect the processing of H-1B, H-1B1, and E-3 temporary work visas, as well as permanent labor certification program (PERM) applications.
