Colleges and students are suing the Department of Homeland Security over a controversial Trump administration immigration policy they argue is “intentionally designed to impose tens of thousands of reentry bars” of up to 10 years on holders of visas typically granted for academic purposes.

The lawsuit, filed by Mayer Brown attorneys in the U.S. District Court for the Middle District of North Carolina, seeks to render unlawful a 2018 policy memorandum that plaintiffs claim “fundamentally alters the calculation of unlawful presence for F, J, and M visa holders.”
