Harvard, Yale and MIT among 9 US universities facing J-1 visa probe

The Trump administration has launched an investigation into nine prominent US universities over the alleged misuse of the J-1 visa programme, with Vice President JD Vance accusing the institutions of relying excessively on foreign researchers in ways that could disadvantage American graduate students and researchers.

The universities under scrutiny include Harvard University, Yale University, Stanford University, Brown University, the University of Pittsburgh, the University of California, Davis, the California Institute of Technology (Caltech), Arizona State University and the Massachusetts Institute of Technology (MIT).

Speaking at a White House briefing on October 8, Vance alleged that some institutions were using the programme to reduce labour costs at the expense of American workers.

“They’re using these visas way too much,” Vance said, calling for greater scrutiny of how universities employ international researchers.

The investigation could bring increased scrutiny to university hiring practices and the use of temporary visas for academic and scientific research. However, the allegations do not establish that any of the nine institutions has violated the law.

Subpoenas issued to universities

Anthony D’Esposito, inspector general at the US Department of Labor, said subpoenas had been issued to the universities as part of the investigation.

Vance said J-1 visa holders account for approximately 61% of researchers working on federally funded projects at the nine institutions, compared with a claimed national average of 38%. The administration has not publicly provided a detailed explanation of how these figures were calculated.

Investigators are expected to examine potential visa violations, foreign financial relationships and possible foreign influence over federally funded research, according to statements made at the briefing.

The probe comes as the Trump administration steps up scrutiny of immigration and employment programmes used by international students, academics, researchers and skilled foreign workers.

What is the J-1 visa programme?

The J-1 visa is part of the US Exchange Visitor Program, which allows eligible foreign nationals to participate in approved academic, research, teaching and other exchange activities.

Universities across the United States use the programme to bring in international scholars, visiting researchers and postdoctoral fellows. These researchers contribute to scientific projects, university laboratories and collaborative research initiatives.

The programme itself is legal, and hiring foreign researchers does not automatically amount to visa fraud or unlawful employment practices. The investigation will seek to establish whether the universities complied with applicable rules and whether their use of the programme violated labour or immigration requirements.

How could the investigation affect international researchers?

The outcome could have implications for international scholars seeking research positions in the United States, particularly if the investigation leads to tighter compliance checks or changes in university sponsorship practices.

Universities may face greater scrutiny over how they recruit foreign researchers, fund research positions and demonstrate compliance with visa requirements. Depending on the findings, any subsequent policy changes could also affect the recruitment of international academics and researchers.

For now, the announcement does not automatically cancel existing J-1 visas, suspend the universities' research activities or establish that the institutions named have committed wrongdoing.

The investigation places the role of international talent in American higher education under renewed scrutiny, highlighting the challenge of balancing domestic labour-market concerns with universities' reliance on global expertise to sustain scientific research and academic collaboration.
