# Visa sponsorship & salary data tools

> U.S. employers that sponsor foreign workers must file wage details with the Department of Labor, and those filings are published as public disclosure files. The two tools here are query builders on top of that data: one finds employers that sponsor visas for a role and location, the other turns filed wages into salary benchmarks such as median and percentiles. Each assembles a ready-to-run configuration and previews a fixed example of the output. Keep in mind this is visa-sponsored wage data, a strong signal but a subset of all U.S. jobs.
