H-1B sponsorship profile: Quartet LLC. Across U.S. Department of Labor LCA disclosures, Quartet LLC filed 45 Labor Condition Applications covering 45 H-1B worker positions between fiscal year 2023 and fiscal year 2026. The employer’s DOL certification rate sits at 95.6% (43 certified of 45 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 Quartet LLC’s H-1B petitions range from $66,560 at the low end to $160,000 at the high end, with a petition-weighted average of $101,084. That range reflects the mix of occupations the company sponsors, led by Software Engineer (10 petitions at $100,000 avg), followed by Senior Software Engineer and Business Intelligence Analyst. 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.
