Tens of thousands of immigrants who had been allowed to temporarily live and work in the United States under the Biden administration have received a seemingly unequivocal message in recent days from the Department of Homeland Security.

Leave “immediately.”

The termination notices, which started being delivered electronically last week, were more indication that migrants who followed the rules set by the last administration may be among the most vulnerable now as President Trump seeks to make good on his campaign promise of mass deportations.

Many migrants who entered the country using the CBP One app — introduced in 2023 to bring order to the chaotic influx at the southwestern border — have been told their legal status would end seven days after the date on their notice. If they failed to depart voluntarily, they would be targeted for enforcement and deported, the notices said.

“They believed they were following the right path by using the government-provided app,” said Joy Tucker, board chairwoman of Kaleidoscope Humanitarian Aid, a nonprofit organization in Tucson, Ariz.

In a twist, at least 10 immigration lawyers, most of whom are U.S. citizens, said that they, too, had received the notices urging them to depart the country, possibly because of a glitch linking their email addresses to the immigration documents of their clients.

Despite a few high-profile roundups of undocumented immigrants by federal law enforcement, the new wave of notices indicates that the bulk of “removals” by the administration is likely to come from the revocation of immigrants’ legal status, not, as Mr. Trump promised, the large-scale deportation of criminal migrants. On Monday, ahead of Mr. Trump’s meeting with the president of El Salvador, Nayib Bukele, the White House singled out about two dozen deportees by name that officials said were criminal gang members.

But noncriminal targets number in the hundreds of thousands. The latest hit came last week when the Trump administration ended temporary protections for more than 10,000 people from Afghanistan and Cameroon. That followed last month’s revocation of a Biden-era program that permitted around 500,000 people from Cuba, Haiti, Nicaragua and Venezuela to stay for two years with work permits, provided they had a financial sponsor and passed a security check. The cancellation, to go into effect on April 24, is being challenged in federal court in Boston.

On Monday afternoon, the same federal judge in Boston, Indira Talwani, moved to temporarily block the Trump administration’s planned effort to revoke the temporary status of migrants who came to the country as part of a Biden-era program.

The judge’s order will set up yet another clash with the Trump administration over its aggressive immigration policies. Many of the immigrants in Arizona, Colorado, Ohio and beyond who received departure orders have legal grounds to remain in the country, according to immigration experts.

In New York City, where 40,000 recent migrants, mostly families with children, are still being housed in dozens of city shelters, notices began arriving last week, according to an email that city officials sent shelter providers on Friday.

“We have been made aware that some clients have received emails from the Department of Homeland Security terminating their parole status seven days from now,” said the email, which redirected any legal questions the migrants might have to a city hotline.

Jethro Eisenstein, an immigration lawyer in New York, said the email was misleading.

“It says in essence, CBP One is over, time for you to leave,” he said, but many of his clients have pending asylum petitions.

In a statement, a senior official with the Department of Homeland Security said U.S. Customs and Border Protection had sent out the parole revocation notifications to the email addresses provided by immigrants, meaning that some “notices may have been sent to unintended recipients.”

“CBP is monitoring communications and will address any issues on a case-by-case basis,” the official said.

In interviews, immigration lawyers who received the parole revocation notices in error said they were puzzled and amused at first — and then worried. Mary Lynn Tedesco, a U.S. citizen and private immigration attorney in Charlotte, N.C., said she had never submitted a parole application on behalf of a client, nor had she ever privately sponsored an immigrant on parole.

Nicole Micheroni, an immigration lawyer in Boston who was born in Newton, Mass., posted her letter on social media, musing, “Does anyone know if you can get Italian citizenship through great-grandparents?” But she and other lawyers said the notice could put undue pressure on immigrant families.

“The language is very aggressive and very threatening, so I could see this email causing a lot of panic and concern to people, whether they are citizens or here on parole or here legally in any other way,” Ms. Micheroni said.

Billy Husher Jr., another U.S. citizen and lawyer who received the notice, said that it was “just a mass email and not any kind of individualized determination.” Mr. Husher, a senior associate at Costas Law Firm in Independence, Ohio, added, “This makes me believe that it’s just a scare tactic to make people give up their due-process rights.”

The move to terminate the status of people who used the app is part of a wider push by the Trump administration to roll back discretionary programs created by the Biden administration, which had allowed about 1.5 million people to be “paroled” into the country.

The parole status shielded immigrants from deportation and granted them employment authorization for two years.

The Homeland Security Department canceled CBP One after Mr. Trump took office, and turned it into a “self-deportation” app, CBP Home, which it hopes migrants will use to prove they have left the United States once they have departed. The administration has also effectively canceled Social Security numbers that immigrants had obtained legally to cut them off from using crucial financial services like bank accounts and credit cards and raise pressure on them to leave.

Migrants who used the CBP One app often waited months in Mexico for an appointment to present themselves at a U.S. port of entry at the southern border. After the appointment, they were typically paroled into the country with court dates for removal hearings in cities around the country. Many received work permits within weeks and later applied for asylum, hoping to win the right to remain in the country long-term.

Among those who just received the termination notice was Frantzdy Jerome, a Haitian immigrant who has been working at an Amazon warehouse near Springfield, Ohio, one of the centers of anti-immigrant fervor during the 2024 presidential campaign.

“D.H.S. is now exercising its discretion to terminate your parole,” said the notice he shared with The New York Times. The last sentence said, “Please leave the United States immediately.”

Mr. Jerome said that he had read the notice repeatedly, until concluding that he might be spared because he had a pending asylum case. One line said that enforcement actions would “result in your removal from the United States — unless you have otherwise obtained a lawful basis to remain here.”

Still, Mr. Jerome worries, he said, because his asylum request has not been approved.

Mr. Jerome said that he planned to keep reporting to work the overnight shift at Amazon, where many Haitian co-workers had received the same notice.

“I’m praying that I can stay in this country and keep working,” said Mr. Jerome, who supports 10 family members in Haiti.

“Conditions in my country are very bad,” he said.

The notices have caused confusion not only for families, said Kathleen Bush-Joseph, a policy analyst at the Migration Policy Institute, “but also for employers trying to figure out if they have to fire people whose work permits expire.”

The work permits normally go with the expiration of protected status. If a migrant has an asylum application, then that person should be able to remain employed, but nothing is clear.

In Denver, Morgain Sanchez, a middle-school teacher, said the families of many of her Venezuelan students had received notices and were panicked.

“They don’t know what they will do,” Ms. Sanchez said.

An Israeli strike killed a security guard and wounded 10 patients at a field hospital in southern Gaza on Tuesday, according to the director of the medical facility.

The deadly attack on the grounds of the Kuwait Specialty Field Hospital came two days after Israel attacked the Al Ahli Arab Hospital in Gaza City, one of the last functioning medical centers in Gaza. Israel has said the strike on the Al Ahli hospital was targeting a Hamas command center, without providing evidence.

On Tuesday, the Israeli military said it was looking into the reports about the strike on the Kuwait Specialty Field Hospital.

Dr. Suhaib al-Hamss, the field hospital’s director, said that the guard was killed protecting the entrance to the facility. Four of the wounded suffered serious injuries, he added.

“It was a powerful strike,” Dr. al-Hamss, 37, said in a phone interview. “Everything fell over.”

The Israeli military offensive in Gaza has caused immense damage to hospitals and the health care system in the enclave. The World Health Organization reported last month that 33 of Gaza’s 36 hospitals had been damaged during the war, and that only 21 remained partly functional. The W.H.O. also warned on Saturday that hospitals in Gaza face a looming medicine shortage because Israel has blocked aid deliveries for six weeks.

Israel has accused Hamas of exploiting health facilities by using them for military purposes — allegations that the militant group has denied.

Dr. al-Hamss said that the hospital’s location was known to the Israeli authorities as it had been shared through intermediaries before the attack. He added that staff were vetted and that Hamas government offices were not hosted at the medical facility.

“We’re not doing anything other than medicine,” he said.

The Kuwait Specialty Field Hospital was treating a minimum of 3,500 patients every day, according to Dr. al-Hamss.

“The hospital,” he said, “is providing a solution to the people in light of the collapse of the heath sector in Gaza.”

Vice President JD Vance predicted that President Trump would make a trade deal with Britain, a country “he really loves,” a comforting sign for a British government that was stung to be placed under a 10 percent tariff by Mr. Trump.

“He admires and loves the king. It is a very important relationship,” Mr. Vance said in an interview published on Tuesday by a British news and opinion website, UnHerd, referring to King Charles III.

Mr. Vance said the White House was working closely with Prime Minister Keir Starmer of Britain and his government. “I think there’s a good chance that, yes, we’ll come to a great agreement that’s in the best interest of both countries,” he said.

Mr. Vance did not go into the details of a potential deal, which are complicated and politically charged in Britain. The country is one of many lining up for talks with the United States since Mr. Trump imposed across-the-board tariffs on dozens of countries, and much larger levies on China.

A senior British official said last week that he believed Treasury Secretary Scott Bessent would focus initially on an agreement with Japan, the fourth-largest trading partner of the United States, after Canada, Mexico and China. The European Union has the largest trading volume with the United States overall, but it is not viewed as a priority in the same way as those other countries.

Still, Mr. Vance softened his tone toward Europe after an acrimonious stretch in which he scolded European leaders, appeared to endorse far-right parties like Alternative for Germany, or AfD, and disparaged the armed forces of Britain and France, both of which fought alongside American troops in Afghanistan.

“I love Europe,” Mr. Vance told UnHerd. “I love European people. I’ve said repeatedly that I think that you can’t separate American culture from European culture.”

It was a far cry from Mr. Vance’s dismissive tone at the Munich Security Conference, where he told European leaders that if they continued to ignore the views of their people, “there is nothing America can do for you, nor for that matter is there anything you can do for the American people.”

Mr. Vance later provoked outrage in Britain and France when he said that a minerals deal being negotiated between the United States and Ukraine was a “better security guarantee than 20,000 troops from some random country that hasn’t fought a war in 30 or 40 years.”

Britain and France have been trying to marshal troops to guarantee Ukraine’s security if a peace settlement with Russia is reached. Britain fought with the United States in Afghanistan and Iraq, while French troops fought in Afghanistan.

But the vice president did not drop his complaint that many European countries have failed to shoulder the burden of their security. “It’s not good for Europe to be the permanent security vassal of the United States,” he told UnHerd.

Mr. Vance exempted Britain and France from that category. (He had insisted that his earlier remarks about “random countries” did not apply to them, though it was not clear to whom else he could have been referring.)

Despite the good will, analysts say the long-awaited trade deal could still be elusive. In previous negotiations, the United States has pushed Britain to accept imports of American beef and poultry. Critics in Britain have for years derided the specter of “chlorinated chicken,” making it hard for any British government to compromise.

Mr. Vance’s choice of UnHerd for the interview was notable. The website was founded in 2017 by a hedge fund manager, Paul Marshall, who was once a donor to Britain’s Liberal Democratic Party, but has since swung right in his political views. Mr. Marshall also owns The Spectator, a right-of-center commentary magazine, and is an investor in GB News, a right-wing news channel.

Auvers-sur-Oise, a village near Paris famed as an artist’s paradise, is also where Vincent Van Gogh spent his final days and it has long drawn tourists to walk in the tortured painter’s last footsteps. But ever since art experts identified his final work before he took his life, there has been strife in the town.

Van Gogh’s final painting was disputed for decades, because he didn’t date his works. But in 2020 experts concluded that gnarled tree roots protruding from a hillside in Auvers, as depicted in his “Tree Roots,” was made on the day he died. This finding may have settled one dispute, but it immediately stirred another, this one between the municipality and the owners of the property where the roots grow.

The main root depicted in the painting — from a black locust tree and dubbed the “elephant” by enthusiasts — abuts a public road. After the discovery of its historical value, the municipality claimed a section of privately owned land near the road as public domain, saying it was necessary for maintenance. Jean-François and Hélène Serlinger, the property owners, fought the village, and an appeals court recently concluded there was no basis for the municipality’s claim.

But the mayor of Auvers, Isabelle Mézières, has pledged to keep fighting, and she can still appeal to a higher court. After the decision, she insisted that the site should belong to the public, not private owners. “The Roots belong to the Auversois!” she wrote on social media, referring to the citizens of the region.

The continued fight over Van Gogh’s tree roots has cast a pall over what is usually a celebratory season in Auvers, population 7,000, where art tourism is a big business that heats up in the spring.

That the village has been depicted by other notable painters, including Pierre Auguste Renoir, Paul Cezanne and Camille Pissaro. has only added to its attraction. Its popularity is such that the French transit authorities run a seasonal line from Paris, dubbed the “Impressionists’ Train,” and people come from afar to see what the local tourist board calls “the open-air museum that Auvers has become over time.”

The property owners say the conflict is endangering the historic site, as the mayor has blocked them and experts from properly protecting the roots since their significance was established. In a phone interview, Mr. Serlinger accused the municipality of using the administrative case as a pretext for “an attempted takeover of a culturally significant site” and of simultaneously endangering the roots by “obstructing the installation of a permanent protective structure.”

The municipality and the mayor declined requests for comment. But it is perhaps fitting that these tree roots should be the subject of such a knotty dispute.

Van Gogh’s famous painting depicting the tangled tree shows “the struggle of life, and a struggle with death,” Wouter van der Veen, the researcher in France who identified the roots, said in 2020.

Still, the painting is bright and lively, made at the end of a productive period in Van Gogh’s troubled existence — after he famously cut off his ear and spent time in an asylum — and the village celebrates the Dutch painter whose work was rejected in life and embraced after his death. Van Gogh is a major attraction, including for the Serlingers.

The couple moved to Auvers in 1996 because Mrs. Serlinger, an artist, wanted to live where Van Gogh had worked. In 2013, they bought a small additional parcel of land near their house, connected to their yard, extending their territory. Only years later did it turn out that the roots on that new property were an important part of art history.

Now, the roots have their own website and nonprofit organization, run by the Serlingers, who say they want to protect the location for the public to enjoy. They’ve partnered with the Van Gogh Europe Foundation, which brings together key locations and museums linked to the painter under the direction of the Van Gogh Museum in Amsterdam. Last year, the Serlingers began opening their yard to visitors for tours.

Mr. Serlinger insists the couple did not intend to make their yard into a destination and has not profited from the tours. He noted that the main root is mostly visible to the public from the road, though the municipality has placed a 10-foot sign there highlighting the find that partially obstructs the view and “disfigures the front of the site.”

It was the enthusiasm of art experts and academics visiting them over the years, that convinced the couple to open up their land to the public, he said. They now charge about $9 for a 30-minute “walk through the landscape of Van Gogh’s final painting,” he added, with funds going to preservation costs.

Saturday was the start of the new tourist season. But the dispute has unsettled the property owners and raised concerns about the preservation of the roots.

“It created a deep sense of insecurity around a site that calls for calm and serenity,” Mr. Serlinger said. “We have a feeling of insecurity with a mayor who is still in a war.”

On Roosevelt Island, she had her home, her friends and the security of a small community where everyone knew her. Cars slowed down for her. Residents helped her cross the road.

But that wasn’t enough, it seems. Like so many before her, she flew the coop, lured across the East River by the bright lights and glamour of Midtown Manhattan. Was she seeking excitement? Danger? A date?

Astoria, the wild turkey who rose to fame last year when she unexpectedly appeared in Midtown, visiting luxury retailers, dining at high-end restaurants and roosting on Park Avenue, returned to Midtown East on Sunday.

Over the past two days, she has had some wild adventures: She has roosted in trees and on balconies, foraged in flower beds and fled from dogs. She even had a run-in with the police. Her movements have delighted and captivated New Yorkers, even as a bevy of dedicated bird-watchers have worried about her safety.

As of early Tuesday, she was still living the high life. She was last seen on Monday night roosting on a balcony around 58th Street, between First Avenue and Sutton Place, said David Barrett, a birder who runs the Manhattan Bird Alert account on X and helps look after Astoria.

Birders say Astoria probably crossed the East River to look for love.

In the days before setting off for Midtown, she had strayed to parts of Roosevelt Island, a residential neighborhood in the East River, where she didn’t usually go, and had been calling out, Mr. Barrett said. “When you put that together with the fact that it’s mating season for wild turkeys, we figured that she’s looking for a mate.”

Since arriving in Midtown on Sunday morning, Astoria appears to have limited her search for a partner to the area around Sutton Place, one of the city’s wealthiest neighborhoods.

It is a fitting locale for a discerning bird, said Whitney Devlin, 80, who lives in the neighborhood, on 58th Street. She arrived home on Monday afternoon to see Astoria, with iridescent glimmers of orange and blue in her brown feathers, sitting in her front courtyard, surrounded by tulips.

“It’s supposed to be a very elegant area,” Ms. Devlin said. “Of course, you saw what she looks like. She’s experienced. She’s been out since 2024.”

She said that Astoria posed well for photos and did not appear perturbed by the crowd of fans that gathered. “I didn’t ask for an autograph,” she added. “I didn’t want to presume.”

Seeing Astoria was the highlight of her day, Ms. Devlin said.

Astoria, who is named for the Queens neighborhood where she may have first been spotted, has evaded capture by the authorities. Videos posted to social media show officials, including some police officers, trying to herd her into a carrier box before she propels herself into the air. The New York Police Department did not immediately respond to a request for comment.

Mr. Barrett, the birder, said that attempts to capture her were counterproductive, because they would frighten her into flying high, where she would be unable to forage for food or water.

He was concerned about how she would fare in the hustle and bustle of Midtown, with its busy traffic and limited places for foraging. On Roosevelt Island, she is well-known and looked after, he said. Cars are few; turkey-crossing signs have been erected to ensure she can cross roads safely; and residents know to watch out for her.

“We hope she realizes the mistake she’s made and flies back soon, maybe tomorrow,” he said. “If she does, she’ll get to eat, she’ll get all the water she needs and she’ll be fine.”

As for her attempts to find a mate? “It’s impossible,” Mr. Barrett said. “She’s the only wild turkey in Manhattan.”

Ms. Delvin said she heard someone in the neighborhood had two pet turkeys but shared some advice: “She’s probably better off single.”
