The Trump administration has taken a bold step against Harvard University. It has blocked the university from admitting new international students. Moreover, it has ordered current foreign students to transfer or lose their legal status.

Homeland Security Cancels Certification

Homeland Security Secretary Kristi Noem made the decision official. She ended Harvard’s certification under the Student and Exchange Visitor Program. This change will begin in the 2025–2026 school year. The department shared this news in a public statement.

Later on Thursday, Noem issued a clear warning. “Let this serve as a warning to all universities and academic institutions across the country,” she wrote.

Conflict Between Harvard and Trump Administration

Since January, the Trump 2.0 administration has taken a tough stance on Harvard. It started cutting funds and creating strict policies. According to officials, Harvard has not done enough to stop antisemitism on campus.

In fact, during the 2024–2025 school year, Harvard had around 6,800 international students. That made up 27% of its total enrollment, based on university data.

Government Plans to Target Other Schools

In addition, the administration plans to expand its campaign. It will target other universities as part of its effort to fight antisemitism nationwide.

According to Homeland Security, Harvard sparked this action by refusing to share certain information. Noem had asked for details about foreign students on visas. However, the university chose not to cooperate.

Noem Sets Deadline for Harvard

Soon after, Noem sent Harvard a letter. She gave the school 72 hours to provide several records. These included information about foreign students and any videos or recordings of their protest activities over the past five years. If Harvard follows through, it may regain its certification.

Harvard Responds Strongly

In response, Harvard called the government’s move illegal. It warned that this would hurt thousands of students. The university also said the action was a form of revenge.

Harvard stated that the decision is “unlawful” and reaffirmed its support for international education.

“We are fully committed to maintaining Harvard’s ability to host our international students and scholars, who hail from more than 140 countries and enrich the University – and this nation – immeasurably,” the university said.

Furthermore, it added, “We are working quickly to provide guidance and support to members of our community. This retaliatory action threatens serious harm to the Harvard community and our country, and undermines Harvard’s academic and research mission.”
