More colleges and state officials are taking legal action against the Trump administration’s new restrictions on international students. They say the new policy harms students’ safety and forces schools to reconsider their plans for the fall. Sixteen states and Washington, D.C. joined Massachusetts in a legal action brought last week in federal court in Boston against the rule. Lawsuits were also brought by Johns Hopkins University and the state of California. The University of California system has said it also plans to take legal action. The efforts support Harvard University and the Massachusetts Institute of Technology in the legal case against U.S. Immigration and Customs Enforcement (ICE). More than 200 universities have signed legal briefs supporting the case against ICE.
