Updated July 23, 2025. Read from US Department of Labor, Office of Foreign Labor Certification. Public domain (U.S. government work). A certified labor condition application (H-1B, H-1B1, E-3) or PERM labor certification is an employer filing the Department of Labor approved. It is not a count of people hired or visas issued. Wages are as the employer filed them, converted to a yearly figure at 2,080 hours; a wage whose unit is missing is left blank. The files show the first worksite of a case.
