About H1BSponsorData

Our Mission

H1BSponsorData provides free, comprehensive access to H1B visa data to help workers, employers, and researchers understand the H1B visa landscape. We believe transparency in immigration data benefits everyone involved in the process.

Data Sources

Our database combines data from multiple official U.S. government sources:

• Department of Labor (DOL) — Labor Condition Application (LCA) disclosure data, updated quarterly. This includes employer names, job titles, salaries, and work locations for all H1B applications.
• U.S. Citizenship and Immigration Services (USCIS) — H1B petition approval and denial data by employer, providing actual petition outcomes.
• PERM Labor Certification — Permanent labor certification (green card sponsorship) data from the DOL, showing employer commitment to long-term sponsorship.
• Bureau of Labor Statistics (BLS) — Occupational Employment and Wage Statistics (OEWS), providing national and state-level median salaries for comparison.

Methodology

We process raw government data through a multi-step pipeline:

1. Import — Raw LCA, USCIS, PERM, and BLS data files are imported and normalized.
2. Normalization — Employer names are standardized (removing suffixes like Inc, LLC, Corp), SOC codes are mapped to current classifications, and locations are geocoded.
3. Aggregation — Data is pre-aggregated into optimized tables for fast querying: employers, occupations, cities, states, industries, and cross-reference tables.
4. Enrichment — H1B salary data is compared against BLS median wages to provide market context.

Data Freshness

Our data is updated quarterly when the Department of Labor releases new LCA disclosure files. The database currently covers fiscal years from FY2015 to the most recent quarter available.
