H-1B sponsorship profile: King County. Across U.S. Department of Labor LCA disclosures, King County filed 18 Labor Condition Applications covering 18 H-1B worker positions between fiscal year 2023 and fiscal year 2025. The employer’s DOL certification rate sits at 94.4% (17 certified of 18 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 King County’s H-1B petitions range from $89,274 at the low end to $179,018 at the high end, with a petition-weighted average of $133,357. That range reflects the mix of occupations the company sponsors, led by Wastewater Capital Project Manager II (2 petitions at $127,131 avg), followed by Master Applications Developer and Engineer III. 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. King County is headquartered in Seattle, WA under NAICS code 921190, and places H-1B workers across 1 state, most heavily in WA. 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 King County ranks. By H-1B petition volume, King County is #10,965 of 119,880 employers nationally and #211 of 2,468 employers headquartered in WA. Both ranks are computed live from the same underlying petition counts, not a separate estimate.
