But the mogul’s New York modeling agency, Trump Model Management, has profited from using foreign models who came to the United States on tourist visas that did not permit them to work here, according to three former Trump models, all noncitizens, who shared their stories with Mother Jones. Financial and immigration records included in a recent lawsuit filed by a fourth former Trump model show that she, too, worked for Trump’s agency in the United States without a proper visa.

Foreigners who visit the United States as tourists are generally not permitted to engage in any sort of employment unless they obtain a special visa, a process that typically entails an employer applying for approval on behalf of a prospective employee. Employers risk fines and possible criminal charges for using undocumented labor.
