The Trump administration has launched an inquiry into nine universities over suspected fraud involving J-1 visas, a program frequently used by international postdoctoral researchers who play a vital role in the U.S. biomedical research sector. The institutions under review—Harvard, Yale, Stanford, Brown, the California Institute of Technology, Arizona State University, MIT, the University of Pittsburgh, and UC Davis—were identified by Vice President J.D. Vance during a press briefing held on Thursday.
According to Vance, these universities employ J-1 visa holders at a rate of 61% for federally funded research, a figure well above the national average of 38%. While this statistic has not yet been independently verified, data from the National Science Foundation indicate that nearly 60% of postdoctoral researchers in science, engineering, and health fields rely on temporary visas, the majority of which are J-1s. The Department of Labor’s inspector general, Anthony D’Esposito, has since ordered these universities to provide documents as part of an investigation into potential visa abuse, foreign influence, or improper financial arrangements that may threaten federally funded research.
D’Esposito described the probe as a critical security issue, stating that institutions violating laws to cut expenses while exposing research to foreign adversaries represent “institutional betrayal.” He emphasized that legal violations would not be tolerated regardless of an institution’s reputation, declaring, “Break the law and screw the American people, and I will personally cuff you in the university square.”

All nine universities have acknowledged receiving subpoenas. MIT’s spokesperson, Kimberly Allen, confirmed in an email that the university received a “very broad subpoena” on Thursday morning that it is now reviewing. She did not elaborate on the details of the subpoena or what kinds of information had been requested. Allen wrote, “Each J-1 visa holder at MIT has been vetted and authorized to come here by the U.S. government, and we take seriously our obligations to follow U.S. law.” Stanford’s Angie Davis affirmed compliance with visa laws and pledged full cooperation. Yale’s Ozan Say made similar assurances, stating the university would examine its records to ensure adherence to federal regulations.
Harvard’s spokesperson confirmed the subpoena but declined to provide additional details. The administration has not disclosed the evidence behind its claims, nor has D’Esposito’s office specified the investigation’s focus or expected duration. This move follows broader Trump administration policies aimed at restricting international students and scholars, including proposals for a $70,000 fee on work authorization programs and revived plans to impose a $100,000 charge on H-1B visas, which are used by foreign workers in specialized fields.
The administration has not outlined specific accusations, but the focus on J-1 visas suggests concerns about universities using temporary worker programs to lower labor costs. Some institutions may argue that flexible visa policies are necessary to attract elite researchers in a highly competitive global market.
