A California skilled nursing facility will pay $24,000 in a settlement over allegations it discriminated against non-United States citizens in the hiring process.

Villa Rancho Bernardo Care Center in San Diego announced the deal with the U.S. Department of Justice on Wednesday. At stake were allegations that the facility required non-citizen, lawful permanent residents to show a permanent resident card, also known as a “green card,” during the interview and hiring process. The DOJ said this standard was not applied to U.S. citizens, who were allowed to show any valid work authorization documentation that they chose, such as a Social Security card or birth certificate.

Permanent residents are not required to show their permanent resident cards, and should have had a choice when interviewing at the facility, the DOJ said.

Officials at Villa Rancho Bernardo did not respond to McKnight’s request for comment by press time Wednesday.

In addition to the civil penalty fine, the facility has agreed to undergo anti-discrimination and Immigration and Nationality Act training, and be subject to monitoring requirements.
