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 KOS Services LLC’s H-1B petitions range from $60,000 at the low end to $93,974 at the high end, with a petition-weighted average of $71,994.

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.
