H-1B sponsorship profile: CoreStack Inc. Across U.S. Department of Labor LCA disclosures, CoreStack Inc filed 17 Labor Condition Applications covering 17 H-1B worker positions between fiscal year 2024 and fiscal year 2025. The employer’s DOL certification rate sits at 100% (17 certified of 17 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 CoreStack Inc’s H-1B petitions range from $90,000 at the low end to $180,710 at the high end, with a petition-weighted average of $139,581. That range reflects the mix of occupations the company sponsors, led by Technical Lead (6 petitions at $155,118 avg), followed by Software Development Engineer and Technical Lead Product Specialist. 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. CoreStack Inc is headquartered in Bellevue, WA under NAICS code 541511, 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 CoreStack Inc ranks. By H-1B petition volume, CoreStack Inc is #11,465 of 119,880 employers nationally and #221 of 2,468 employers headquartered in WA. Both ranks are computed live from the same underlying petition counts, not a separate estimate.
