Worksites
Charles River Laboratories, Inc. — H-1B worksites
Every place of employment declared on Charles River Laboratories, Inc.'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.

Worksites rolled up to the state on the filing. Each state links to every H-1B sponsor with work there, not only this one.

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.
