Notes and limits

Past H-1B approvals do not mean the company is hiring or sponsoring now. Licensed to sponsor does not mean hiring now.
H-1B counts are petition approvals from the USCIS H-1B Employer Data Hub (FY2025 complete; FY2026 partial), matched by normalised employer name plus state. 620 of 3869 growing 50–1,000-employee US companies matched (16%). Approvals count petitions, not people.
Source of approvals: U.S. Citizenship and Immigration Services, H-1B Employer Data Hub (public information). Not affiliated with or endorsed by USCIS.
Growth = 1-year change in headcount from licensed B2B firmographic and technographic data.
Growth is shown as a band: +20–50%, +50–100%, +100–200% or 200%+ (estimated). Within a band, companies are listed largest first; the order inside a band is not a growth ranking.
"200%+ (estimated)" means the growth figure is above 200% and has not been verified; treat it as an estimate.
Likely branches of larger groups and university units are left out.
Company-level data only. Not legal or immigration advice.
