In Monday’s lawsuit, Justice officials said the colleges discriminated against nearly 250 noncitizen job applicants by mandating that they fill out more documents than required by law to prove their eligibility to work. That violated the federal Immigration and Nationality Act, the department said.

The law’s antidiscrimination provision “makes it unlawful to treat authorized workers differently during the hiring process based on their citizenship status,” said Thomas E. Perez, assistant attorney general for Justice’s Civil Rights Division. He said the government “is acting now to remedy this pattern or practice of discrimination.”
