H-1B sponsorship profile: Sigma-Aldrich Corporation. Across U.S. Department of Labor LCA disclosures, Sigma-Aldrich Corporation filed 80 Labor Condition Applications covering 80 H-1B worker positions between fiscal year 2023 and fiscal year 2026. The employer’s DOL certification rate sits at 96.3% (77 certified of 80 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 Sigma-Aldrich Corporation’s H-1B petitions range from $71,400 at the low end to $196,000 at the high end, with a petition-weighted average of $126,954. That range reflects the mix of occupations the company sponsors, led by Website Analyst II (3 petitions at $90,000 avg), followed by Senior Data Scientist and Architect. 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.

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.
