The Trump administration revoked Harvard University’s ability to enroll international students in its escalating battle with the Ivy League school, saying thousands of current students must transfer to other schools or leave the country.
The Department of Homeland Security announced the action Thursday, saying Harvard has created an unsafe campus environment by allowing “anti-American, pro-terrorist agitators” to assault Jewish students on campus. It also accused Harvard of coordinating with the Chinese Communist Party, saying it hosted and trained members of a Chinese paramilitary group as recently as 2024.
“This means Harvard can no longer enroll foreign students and existing foreign students must transfer or lose their legal status,” the agency said in a statement.
Harvard enrolls almost 6,800 foreign students at its campus in Cambridge, Massachusetts, accounting for more than a quarter of its student body. Most are graduate students, coming from more than 100 countries.
Harvard called the action unlawful and said it’s working to provide guidance to students.
“This retaliatory action threatens serious harm to the Harvard community and our country, and undermines Harvard’s academic and research mission,” the university said in a statement.
The Trump administration’s clash with Harvard, the nation’s oldest and wealthiest university, has intensified since it became the first to openly defy White House demands for changes at elite schools it has criticized as hotbeds of liberalism and antisemitism. The federal government has cut $2.6 billion in federal grants to Harvard, forcing it to self-fund much of its sprawling research operation. President Donald Trump has said he wants to strip the university of its tax-exempt status.

The threat to Harvard’s international enrollment stems from an April 16 request from Homeland Security Secretary Kristi Noem, who demanded that it provide information about foreign students that might implicate them in violence or protests that could lead to their deportation.
In a letter to Harvard on Thursday, Noem said the school’s sanction is “the unfortunate result of Harvard’s failure to comply with simple reporting requirements.” It bars Harvard from hosting international students for the upcoming 2025-26 school year.
Noem said Harvard can regain its ability to host foreign students if it produces a trove of records on foreign students within 72 hours. Her updated request demands all records, including audio or video footage, of foreign students participating in protests or dangerous activity on campus.
The revocation opens a new front in a closely watched battleMany of Harvard’s punishments have come through a federal antisemitism task force that says the university failed to protect Jewish students from harassment and violence amid a nationwide wave of pro-Palestinian protests.
Homeland Security officials echoed those concerns in their Thursday announcement. It offered examples, including a recent internal report at Harvard, finding that many Jewish students reported facing discrimination or bias on campus.
It also tapped into concerns that congressional Republicans have raised about ties between U.S. universities and China. Homeland Security officials said Harvard provided training to the Xinjiang Production and Construction Corps as recently as 2024. As evidence, it provided a link to a Fox News article, which in turn cited a letter from House Republicans.
Asked for comment on the alleged coordination with the Chinese Communist Party, a Harvard spokesperson said the university will be responding to the House Republicans’ letter.
Ted Mitchell, president of the American Council on Education, called the latest action an “illegal, small-minded” overreach.
“I worry that this is sending a very chilling effect to international students looking to come to America for education,” he said.
The Trump administration has leveraged the system for tracking international students’ legal status as part of its broader attempts to crack down on higher education. What was once a largely administrative database has become a tool of enforcement, as immigration officials revoked students’ legal status directly in the system.
Those efforts were challenged in court, leading to restorations of status and a nationwide injunction blocking the administration from pursuing further terminations.
