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.

FAQ
- Will these companies sponsor my H-1B?
- Not necessarily. Past H-1B approvals do not mean the company is hiring or sponsoring now. Licensed to sponsor does not mean hiring now. Check the job advert and ask the recruiter early.
- Where do the H-1B numbers come from?
- The USCIS H-1B Employer Data Hub (FY2025, and FY2026 so far), matched to each company by name and state. Counts are petition approvals, not people.
- Why "beyond the giants"?
- Free sponsor sites rank by filing volume, so the biggest filers come first and get the most applicants. This list keeps 50–1,000-employee companies that grew 20%+ in a year.
- Where does the growth figure come from?
- 1-year headcount growth from licensed B2B firmographic and technographic data, company-level only. Figures over 200% are estimates.
