H-1B sponsorship profile: National Rubber Corporation. Across U.S. Department of Labor LCA disclosures, National Rubber Corporation filed 20 Labor Condition Applications covering 20 H-1B worker positions between fiscal year 2023 and fiscal year 2025. The employer’s DOL certification rate sits at 100% (20 certified of 20 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 National Rubber Corporation’s H-1B petitions range from $52,728 at the low end to $94,702 at the high end, with a petition-weighted average of $68,722. That range reflects the mix of occupations the company sponsors, led by MECHANICAL ENGINEER (5 petitions at $74,189 avg), followed by Software Engineer, Industrial and SOFTWARE 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.
