Worksites
Airline Tariff Publishing Company (ATPCO) — H-1B worksites
Every place of employment declared on Airline Tariff Publishing Company (ATPCO)'s certified labor condition applications. A worksite is where the sponsored work is performed, which is not necessarily the company address — and the count beside each is filings naming that site, not people working at it.

1 filing name this site.
Share of worksite filings at that single busiest site. A high number means relocation, not remote work, is the default assumption.

Two addresses appear in this dataset and they answer different questions. The employer address on the company page identifies the legal entity — with the phone number and NAICS code, it is how you tell two companies with the same name apart. A worksite is where the work is performed, and for an employer that places workers at client sites the two are rarely the same place. How these pages are built.
