How to read these numbers

Illinois here means the first worksite on the case is in Illinois. Employers based elsewhere account for 9,591 of these cases, since their filed employer state is not IL.

Names appear as filed. Of the 25 top employers, 23 file under more than one spelling, and we do not join them. Six of the 25 carry a staffing or consulting word in the name, and three a university word. Job titles are the employer's own, so Ernst & Young U.S. LLP's comes with a filing code.

Each offered wage is the low end of the range on the application, converted to a year. The 10 Illinois cases with no wage stay out of the medians.

The Department of Labor publishes the file, the fiscal 2026 labor condition application disclosure data through the third quarter, on its OFLC performance data page.
