Every U.S. employer petition for foreign labor certification, at case granularity. Names the employer, worksite, occupation (SOC), wage offered, prevailing wage, attorney/lawfirm, and decision outcome. The labor market's 'who pays what for visa workers' ledger: H-2A farmworker contractors, H-2B body shops, PERM green-card filings, H-1B LCAs. DOL OFLC publishes this as quarterly XLSX bulk files (100-150 columns, 50K-1M rows per program per quarter) gated behind Akamai. The data exposes wage-suppression, top-employer concentration, and immigration lawyer churn.
