In the span of a week, a hush has descended on higher education in the United States.
International students and faculty have watched the growing crackdown on pro-Palestinian protesters at Columbia University with apprehension. Some say they are familiar with government crackdowns but never expected them on American college campuses.
The elite New York City university has been the focus of the Trump administration’s effort to deport foreigners who took part in pro-Palestinian demonstrations at colleges last year.
Federal immigration agents have arrested two foreigners — one of them a student — who protested last year at Columbia. They’ve revoked the visa of another student, who fled the U.S. this week. Department of Homeland Security agents also searched the on-campus residences of two Columbia students on Thursday but did not make any arrests there.
GOP officials have warned it’s just the beginning, saying more student visas are expected to be revoked in the coming days.
Columbia’s Graduate School of Journalism issued a statement reporting “an alarming chill” among its foreign students in the past week.
“Many of our international students have felt afraid to come to classes and to events on campus,” said the statement signed by “The Faculty of Columbia Journalism School.”
It added: “They are right to be worried.”
International students and faculty across the U.S. say they feel afraid to voice opinions or stand out on campus for fear of getting kicked out of the country.
“Green-card-holding faculty members involved in any kind of advocacy that might be construed as not welcome by the Trump administration are absolutely terrified of the implications for their immigration status,” said Veena Dubal, a law professor at the University of California, Irvine.
Dubal, who is also general counsel for the American Association of University Professors, says some international faculty are now shying away from discourse, debate, scholarly research and publishing articles in peer-reviewed journals.
“We are literally not hearing their voices. There is a silencing happening that has a huge impact on the vibrancy of higher education,” Dubal said. “People are very, very scared.”
The first publicly known arrest occurred last Saturday, when federal immigration agents arrested Mahmoud Khalil, a prominent Palestinian activist and outspoken graduate student, in the lobby of his apartment building near the Columbia campus.
Khalil has become the face of President Donald Trump’s drive to punish what he calls antisemitic and anti-American protests that swept U.S. campuses last year. Khalil, a legal U.S. resident with a green card, is being held in a federal detention complex in Louisiana.
Students and faculty who participated in the protests at Columbia have insisted criticizing Israel and advocating for Palestinian rights isn’t antisemitic. Some Jewish students and faculty say the anti-Israel rhetoric made them feel unsafe.
Civil rights advocates say the detention of Khalil is an assault on free speech. But the ongoing arrests send a wider message that disagreeing with the Trump administration could get you kicked out of the country, said Brian Hauss, a senior staff attorney at the American Civil Liberties Union.
“If the administration can do this to Mr. Khalil because of the speech about Palestine, it can do it to any non-U.S. citizen who takes a position on hot-button global issues, including the war between Russia and Ukraine, the tariffs imposed against U.S. allies or the rise of far-right political parties in Europe,” he said.
That worry has spread outside New York.
A Bangladeshi student at Louisiana State University, who agreed to speak only on condition of anonymity for fear of being targeted by authorities, said she has stopped posting about anything political on social media since the first arrest at Columbia. She fears losing her green card.
“I feel like it’s not safe for me to share those things anymore because I have a fear that a quote-unquote ‘authoritarian regime’ is lurking over social media posts,” the student said. When she lived in Bangladesh, she said, people could be arrested for posting dissent on social media. “What I fear is a similar situation in the United States.”
