Across U.S. Department of Labor LCA disclosures, Ispero LLC filed 59 Labor Condition Applications covering 59 H-1B worker positions between fiscal year 2023 and fiscal year 2025. The employer’s DOL certification rate sits at 98.3% (58 certified of 59 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 Ispero LLC’s H-1B petitions range from $75,000 at the low end to $109,283 at the high end, with a petition-weighted average of $94,840. That range reflects the mix of occupations the company sponsors, led by Software Developer (32 petitions at $97,924 avg), followed by Programmer 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.
