President Donald Trump’s administration lashed back at Harvard University on Wednesday, with the Department of Homeland Security cutting over $2.7 million in grants and threatening to cancel all student visas, according to a press release obtained exclusively by The Free Press. The move comes two days after Harvard refused to agree to a series of demands by the administration, and Harvard’s president Alan Garber said that the university “will not surrender its independence or relinquish its constitutional rights.”

The Trump administration has begun a new wave of visa revocations for international students studying at American universities.

Universities across America said over the weekend that the visas of several international students were revoked. It's unclear if the visa revocations are associated with anti-Israel actions by the affected international students.

The Harvard International Office announced Sunday that three students and two recent graduates from the university have had their student visas revoked amid the Trump administration’s crackdown.

The office did not release the students’ names and said it has referred them to legal counsel. The reasoning for the revocation is unknown, but the office said it was made during a routine records review. 

Colleges around the country are reporting some of their international students’ visas are being revoked unexpectedly, expressing alarm over what appears to be a new level of government scrutiny.

Visas can be canceled for a number of reasons, but college leaders say the government has been quietly terminating students’ legal residency status with little notice to students or schools. That marks a shift from past practice and leaves students vulnerable to detention and deportation.

Secretary of State Marco Rubio on Saturday announced the U.S. will revoke visas held by South Sudanese passport holders and no others will be issued, effective immediately.

Rubio attributed the change to "the failure of South Sudan's transitional government to accept the return of its repatriated citizens in a timely manner," according to a statement posted on X.

A crackdown on foreign students is alarming college leaders, who say the Trump administration is using new tactics and vague justifications to push some students out of the country.

College officials worry the new approach will keep foreigners from wanting to study in the U.S.

Students stripped of their entry visas are receiving orders from the Department of Homeland Security to leave the country immediately — a break from past practice that often permitted them to stay and complete their studies.

Over the past several weeks, a handful of student visa holders and other legal residents have faced deportation for nebulous allegations that they supported terrorism—often being detained and taken away by immigration officials with seemingly no due process, or even an allegation of criminal wrongdoing. Shockingly, the number of affected individuals has reached into the hundreds. On Thursday, Secretary of State Marco Rubio revealed that he has personally intervened to cancel the visas of around 300 students.

A doctoral student from the University of Alabama has been detained by federal immigration authorities, according to the school.

Alireza Doroudi, an Iranian national studying mechanical engineering, was taken into custody by US Immigration and Customs Enforcement (ICE) officers at his off-campus home in Tuscaloosa around 5 a.m. Tuesday, UA’s student paper The Crimson White reported.

University officials confirmed that a graduate student had been detained by federal immigration authorities, but did not confirm the identity, citing privacy reasons.

There was no explanation, no warning. One minute, I was in an immigration office talking to an officer about my work visa, which had been approved months before and allowed me, a Canadian, to work in the US. The next, I was told to put my hands against the wall, and patted down like a criminal before being sent to an Ice detention center without the chance to talk to a lawyer.

A French scientist was denied entry to the US after immigration officials found text messages that were critical of Donald Trump which they said “could be considered to be terrorism”.

The researcher, who has not been named, was on his way to a conference in Houston, Texas, when officers pulled him aside for a random check and searched his work computer and personal phone, the French newspaper Le Monde reported.
