Worksites

Columbia University — H-1B worksites

Every place of employment declared on Columbia University'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.

Full filing record
Worksites
52

Distinct addresses declared as a place of employment.

States
2

Where the declared work happens, which is not where the company is registered.

Busiest site
New York, NY

17 filings name this site.

Concentration
11%

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

By state

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

Filings can name several worksites, so state totals do not have to add up to the employer's filing count.

Ranked by how many filings name the site. Addresses are reproduced exactly as written on the application — nothing is geocoded, deduplicated by fuzzy match, or corrected.

154 worksite filings in total. A count is filings naming the site, not people at it.

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.
