H-1B sponsorship profile: OSF Healthcare System. Across U.S. Department of Labor LCA disclosures, OSF Healthcare System filed 221 Labor Condition Applications covering 221 H-1B worker positions between fiscal year 2023 and fiscal year 2026. The employer’s DOL certification rate sits at 88.7% (196 certified of 221 filed), a useful proxy for how cleanly their prevailing-wage attestations pass the Labor Department’s preliminary review before USCIS adjudication.

Compensation spread. Offered wages on OSF Healthcare System’s H-1B petitions range from $40,410 at the low end to $640,000 at the high end, with a petition-weighted average of $81,127. That range reflects the mix of occupations the company sponsors, led by Clinical Lab Scientist (51 petitions at $74,059 avg), followed by Clinical Laboratory Scientist and Internal Medicine Resident. H-1B salaries reported on LCAs must meet or exceed the DOL prevailing wage for the role and worksite, so the spread also tracks wage-level geography and seniority.

Geographic footprint. OSF Healthcare System is headquartered in Peoria, IL under NAICS code 62211, and places H-1B workers across 1 state, most heavily in IL. Combined, these signals give a granular view of how one employer uses the H-1B program, volume, approval cleanliness, wage posture, and where the jobs actually sit on the map.
