Real filing data, not estimates

Reads actual H-1B LCA petitions submitted to the DOL — every role name, salary, and wage level is from a real filing.

What roles get sponsored

Counts which job titles appear most in 2025 filings so you can see if a company is tech-heavy, non-tech, or mixed.

Seniority from wage levels

DOL wage levels (I–IV) are a reliable seniority proxy — Level I is entry, Level IV is senior. The AI tells you what mix this company typically sponsors.

Year-over-year sponsorship trend

Compares annual filing counts to tell you whether this company's H-1B sponsorship is growing, stable, or declining.
