H-1B sponsorship profile: Tronox LLC. Across U.S. Department of Labor LCA disclosures, Tronox LLC filed 4 Labor Condition Applications covering 4 H-1B worker positions between fiscal year 2024 and fiscal year 2025. The employer’s DOL certification rate sits at 100% (4 certified of 4 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 Tronox LLC’s H-1B petitions range from $90,000 at the low end to $190,000 at the high end, with a petition-weighted average of $132,750. That range reflects the mix of occupations the company sponsors, led by Senior Manager, IT Audit and Data Analytics (1 petitions at $190,000 avg), followed by Lead Optimization Engineer, Integrated Business Planning and IBP Optimization 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.

Geographic footprint. Tronox LLC is headquartered in Stamford, CT under NAICS code 325130, and places H-1B workers across 3 states, most heavily in MD, CT, TX. 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.

Where Tronox LLC ranks. By H-1B petition volume, Tronox LLC is #30,742 of 119,880 employers nationally and #324 of 1,323 employers headquartered in CT. Both ranks are computed live from the same underlying petition counts, not a separate estimate.
