Court halts four-year research visa cap as lawsuit proceeds

A federal judge issued a preliminary injunction blocking the DHS from implementing a four-year cap on duration-of-status visas for foreign students and postdocs, ruling the rule likely violated the Administrative Procedure Act and questioning its national-security justification. The injunction preserves the current policy while the case advances, a decision with potential consequences for the U.S. biomedical research workforce that relies heavily on international scholars.
