Notes
Source: US Department of Labor OFLC LCA disclosure data (FY2025 and FY2026 Q1–Q3) and USCIS H-1B Employer Data Hub (FY2021–FY2023), matched by normalized employer name. An LCA is filed before an H-1B petition and doesn’t mean a visa was issued. Past filings don’t guarantee that a specific role will be sponsored. How we build these pages · Request a correction
