H-1B sponsorship profile: Southern Research Institute. Across U.S. Department of Labor LCA disclosures, Southern Research Institute filed 24 Labor Condition Applications covering 24 H-1B worker positions between fiscal year 2023 and fiscal year 2025. The employer’s DOL certification rate sits at 100% (24 certified of 24 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 Southern Research Institute’s H-1B petitions range from $60,000 at the low end to $150,000 at the high end, with a petition-weighted average of $87,242. That range reflects the mix of occupations the company sponsors, led by Scientist I (10 petitions at $72,995 avg), followed by Scientist II and Scientist 3. 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. Southern Research Institute is headquartered in Birmingham, AL under NAICS code 54171, and places H-1B workers across 1 state, most heavily in AL. 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 Southern Research Institute ranks. By H-1B petition volume, Southern Research Institute is #8,821 of 119,880 employers nationally and #29 of 609 employers headquartered in AL. Both ranks are computed live from the same underlying petition counts, not a separate estimate.
