Across U.S. Department of Labor LCA disclosures, United Biosource LLC filed 12 Labor Condition Applications covering 12 H-1B worker positions between fiscal year 2023 and fiscal year 2025. The employer’s DOL certification rate sits at 100% (12 certified of 12 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 United Biosource LLC’s H-1B petitions range from $93,750 at the low end to $173,638 at the high end, with a petition-weighted average of $139,900. That range reflects the mix of occupations the company sponsors, led by Senior Manager Software Development Engineer (3 petitions at $150,926 avg), followed by Senior IT Architect and Sr. Data Warehouse Engineer. 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.
