President Trump’s order closing the nation’s borders to people from seven predominantly Muslim countries echoed across Boston’s academic institutions and research laboratories Saturday, blocking some scholars from entering the country and leaving scores more in limbo.

The directive, which also halts refugees worldwide from entering the United States for 120 days, prompted leaders at schools such as the Massachusetts Institute of Technology and Northeastern University to offer support to students and academics whose lives might be upended by the order.

The full extent of the upheaval triggered by the new rules wasn’t immediately clear, and a federal judge’s decision late Saturday night to halt deportations of refugees and those with valid visas added a layer of uncertainty. But research groups at Harvard Medical School and Brigham and Women’s Hospital were among those who lost incoming scholars to the travel ban.

Late Saturday at the John Joseph Moakley United States Courthouse, immigration lawyers and the American Civil Liberties Union of Massachusetts filed a suit on behalf of two associate professors from the University of Massachusetts Dartmouth who are Iranian nationals. According to the suit, Mazdak Pourabdollah Tootkaboni and Arghavan Louhghalam had been detained at Logan International Airport for three hours that evening under Trump’s immigration order.

A White House petition was also launched on behalf of an MIT student who was blocked from returning to Boston from Iran, where she spent winter break at home.

A Northeastern spokesman said the new rules potentially affect more than 200 people at the university, most of whom are already on campus. Other schools didn’t provide tallies.

The order went into effect Friday night and affects travelers from Iran, Iraq, Libya, Somalia, Sudan, Syria, and Yemen, including green card holders. US Customs and Border Protection officials didn’t respond to messages, but a spreadsheet created by an MIT professor to track those affected nationwide had 120 to 130 entries by Saturday afternoon.

Most were Iranian nationals and included people who hold green cards, immigrant and nonimmigrant visas, and dual citizenships.

“It’s extremely frustrating. It is disrupting people’s lives,” said Hazhir Rahmandad, the MIT professor who created the spreadsheet and shared it on social media.

“We have PhD students who are in trouble. We have a lot of graduate applicants that we might not be able to get. We have colleagues who are stranded. Some people we might be recruiting for our faculty positions might consider the US to be untenable,” said Rahmandad, who was born in Iran and naturalized as a US citizen in 2010.

He said his parents, who hold green cards, had planned a visit from Iran to celebrate birthdays for their grandchildren, twins who are turning 2.

“At a personal level, this is not the country that I knew and I trusted and I have adopted as my new home,” Rahmandad said. “I lived through the Iran-Iraq War and I don’t think I was as stressed as what I’m facing these days. It’s so far from our values.”

Among others whose plans were disrupted was Seyed Soheil Saeedi Saravi, a scientist from Iran, who was planning to come to Boston with his wife to work at a research laboratory specializing in cardiovascular disease at Brigham and Women’s Hospital.

Now his visa has been suspended for three months.

“Many Iranians are successful persons in the field of science and trade in US. We are peaceful people and we are out of political games,” Saravi, 30, wrote in an e-mail. “We learn, research, work for development of our country and help to improve the public health of global populations. . . . I am so sorry for this decision.”

Dr. Thomas Michel, a cardiologist who hired Saravi to work in his lab, got the news Friday. He said the travel ban is jeopardizing the country’s position in the scientific community.

“So many people who have been trained in science in this country have gone on to do amazing things in the US and their home countries,” Michel said. “That is being undermined.”

Samira Asgari, an Iranian who holds a doctorate from the École Polytechnique Fédérale de Lausanne in Switzerland, was traveling to Boston to begin working on a tuberculosis project at a Harvard Medical School laboratory — but she and her boyfriend were turned away at the Frankfurt airport.

“They took me a few meters away and took my passport and told me my visa’s not valid,” Asgari said in a Skype interview. “I told him I do have a valid visa, but he told me that it doesn’t matter. I asked him, ‘What can I do now?,’ and he told me to go home.”

She would have worked under Dr. Soumya Raychaudhuri, a rheumatologist at Brigham and Women’s Hospital, who told the Globe he “couldn’t believe that somebody with a visa with her standing would be denied entry.”

Asgari was granted a J-1 Visa to work in the United States, Raychaudhuri said. She was also awarded two years of research funding from the Swiss National Science Foundation.

“I was really ready to go,” Asgari said. “I had done everything right.”

At Logan Airport, immigration lawyers hung fliers offering free legal assistance to people affected by Trump’s actions. They were joined by Attorney General Maura Healey, US Senator Elizabeth Warren, and demonstrators who held proimmigration signs with messages such as, “No Ban” and “No Wall.”

Healey called Trump’s order unconstitutional, saying his actions violated the rights of immigrants who have already been vetted and have a legal right to return to the United States.

Church said the restriction on green card holders is especially onerous because those people have already gone through extensive interviews and background checks.

People who enter through the US Refugee Resettlement Program are processed at six airports in places such as New York, Chicago, and Los Angeles, but not in Boston, she said.

Northeastern’s president, Joseph E. Aoun, and several other school officials sent an e-mail to members of the university community saying they should feel safe there.

“We, the leadership of the university, stand with you and will pursue every means available to safeguard each of you — students, faculty, and staff,” the e-mail said.

Dean Cavaretta, the former state director of the Trump campaign, said the executive order is not intended to rid the country of students and other people who have positively contributed to the economy. He hopes Massachusetts residents will “take a breath” and give the Trump administration time to create a process for allowing legal residents while keeping the country safe.

“I recognize the disruption and inconvenience this is going to cause especially for a multicultural and highly academic state like Massachusetts,” he said.

“I think we know enough about President Trump to know that he can be bold and he’s going to see this through.”

At Boston University, neuroscience major Raya Bidshahri, 21, said the travel ban means her parents won’t be able to come from Iran for her graduation in the spring. Bidshahri was born in Iran, but her family has a permanent residence in Dubai.

She said her parents worked tirelessly so she could attend school in the United States.

“They’re devastated that this has taken such a turn,” said Bidshahri, who plans to move to Canada after graduation to establish an education business with others.

Nael Hafez, a Syrian-born American citizen who lives in Concord, said the executive order is “tearing families apart.”

His cousin, a legal resident who lives in Watertown, traveled to Syria in November to take care of his sick mother. He is supposed to return in February, but his family is worried he’ll be stopped at the airport.

“I happen to be a veteran, and this is not the country that I fought for,” he said.

“I was 11 years old when I raised my right hand and took the first oath to defend the Constitution of the United States. Many Americans have never sworn in, and for my allegiance and for my patriotism to be questioned because of where I was born, that’s insane.”
