DOL H-1B and PERM Labor Certifications

Before a US employer can hire a worker on an H-1B visa (or an H-1B1 or E-3), it files a Labor Condition Application with the Department of Labor: the job and its occupation code, the wage it will pay against the prevailing wage for the role, every place the worker will work, and the attorney who filed. DOL’s Office of Foreign Labor Certification certifies or denies it and publishes every determination. It is the most direct public record of which roles a company hires for from abroad and what it pays. Every determination since fiscal year 2020, with every worksite, organized and ready to query, and brought up to date as DOL publishes each quarter. The employer’s FEIN, published from fiscal year 2024, joins a filing exactly to the same company’s SEC filings. To sponsor a worker for permanent residence, the employer then files a PERM labor certification: the job and its requirements, the offered and prevailing wage, how it recruited US workers first, and, on the form used until 2023, the worker’s citizenship, current visa and education. Every PERM determination since fiscal year 2020 is here too, on both forms.

The whole source, organized and ready to query: every endpoint on this page answers in milliseconds. Every response carries as_of: how current the data is. How datasets work.
