How Trump has targeted Harvard's international students — and what the latest court ruling means

President Donald Trump and his administration have tried several tactics to block Harvard University's enrollment of international students, part of the White House's effort to secure policy changes at the private, Ivy League college.

Targeting foreign students has become the administration's cornerstone effort to crack down on the nation's oldest and wealthiest college. The block on international enrollment, which accounts for a quarter of Harvard's students and much of its global allure, strikes at the core of Harvard's identity. Courts have stopped some of the government's actions, at least for now — but not all.

In the latest court order, a federal judge on Friday put one of those efforts on hold until a lawsuit is resolved. But the fate of Harvard's international students — and its broader standoff with the Trump administration — remain in limbo.

Here are all the ways the Trump administration has moved to block Harvard's foreign enrollment — and where each effort stands.

Homeland Security tries to revoke Harvard's certification to host foreign students

In May, the Trump administration tried to ban foreign students at Harvard, citing the Department of Homeland Security's authority to oversee which colleges are part of the Student Exchange and Visitor Program. The program allows colleges to issue documents that foreign students need to study in the United States.

Harvard filed a lawsuit, arguing the administration violated the government's own regulations for withdrawing a school's certification.

Within hours, U.S. District Judge Allison Burroughs in Boston put the administration's ban on hold temporarily — an order that had an expiration date. On Friday, she issued a preliminary injunction, blocking Homeland Security's move until the case is decided. That could take months or longer.

The government can and does remove colleges from the Student Exchange and Visitor Program, making them ineligible to host foreign students on their campus. However, it's usually for administrative reasons outlined in law, such as failing to maintain accreditation, lacking proper facilities for classes, failing to employ qualified professional personnel — even failing to ''operate as a bona fide institution of learning.'' Other colleges are removed when they close.

Notably, Burroughs' order Friday said the federal government still has authority to review Harvard's ability to host international students through normal processes outlined in law. After Burroughs' emergency block in May, DHS issued a more typical ''Notice of Intent to Withdraw'' Harvard's participation in the international student visa program.

''Today's order does not affect the DHS's ongoing administrative review,'' Harvard said Friday in a message to its international students. ''Harvard is fully committed to compliance with the applicable F-1 (student visa) regulations and strongly opposes any effort to withdraw the University's certification.''

Trump has sought to ban U.S. entry for incoming Harvard students

Earlier this month, Trump himself moved to block entry to the United States for incoming Harvard students, issuing a proclamation that invoked a different legal authority.

Harvard filed a court challenge attacking Trump's legal justification for the action — a federal law allowing him to block a ''class of aliens'' deemed detrimental to the nation's interests. Targeting only those who are coming to the U.S. to study at Harvard doesn't qualify as a ''class of aliens,'' Harvard said in its filing.

Harvard's lawyers asked the court to block the action. Burroughs agreed to pause the entry ban temporarily, without giving an expiration date. She has not yet ruled on Harvard's request for another preliminary injunction, which would pause the ban until the court case is decided. ''We expect the judge to issue a more enduring decision in the coming days,'' Harvard told international students Friday.

At the center of Trump's pressure campaign against Harvard are his assertions that the school has tolerated anti-Jewish harassment, especially during pro-Palestinian protests. In seeking to keep Harvard students from coming to the U.S., he said Harvard is not a suitable destination. Harvard President Alan Garber has said the university has made changes to combat antisemitism and will not submit to the administration's demands for further changes.

The administration has stepped up scrutiny of Harvard scholars' and students' visas

In late May, Secretary of State Marco Rubio directed U.S. embassies and consulates to start reviewing social media accounts of visa applicants who plan to attend, work at or visit Harvard University for any signs of antisemitism.

On Wednesday, the State Department said it was launching new vetting of social media accounts for foreigners applying for student visas, and not just those seeking to attend Harvard. Consular officers will be on the lookout for posts and messages that could be deemed hostile to the United States, its government, culture, institutions or founding principles, the department said, telling visa applicants to set their social media accounts to ''public.''

In reopening the visa process, the State Department also told consulates to prioritize students hoping to enroll at colleges where foreigners make up less than 15% of the student body, a U.S. official familiar with the matter said. The official spoke on condition of anonymity to detail information that has not been made public.

Foreign students make up more than 15% of the total student body at almost 200 U.S. universities — including Harvard and the other Ivy League schools, according to an Associated Press analysis of federal education data from 2023. Most are private universities, including all eight Ivy League schools.

Some Harvard students are also caught up in the government's recent ban against travel to the U.S. by citizens of 12 nations, mostly in Africa and the Middle East. The Trump administration last weekend called for 36 additional countries to commit to improving vetting of travelers or face a ban on their citizens visiting the United States.

International students make up half the students at some Harvard programs

Harvard sponsors more than 7,000 people on a combination of F-1 and J-1 visas, which are issued to students and to foreigners visiting the U.S. on exchange programs such as fellowships. Across all the schools that make up the university, about 26% of the student body is from outside the U.S.

But some schools and programs, by nature of their subject matter, have significantly more international students. At the Harvard Kennedy School, which covers public policy and public administration, 49% of students are on F-1 visas. In the business school, one-third of students come from abroad. And within the law school, 94% of the students in the master's program in comparative law are international students.

The administration has imposed a range of sanctions on Harvard since it rejected the government's demands for policy reforms related to campus protests, admissions, hiring and more. Conservatives say the demands are merited, decrying Harvard as a hotbed of liberalism and antisemitism. Harvard says the administration is illegally retaliating against the university.
