Some hospitals in the United States are without essential staff because international doctors who were set to start their medical training this month were delayed by the Trump administration’s travel and visa restrictions.

It’s unclear exactly how many foreign medical residents were unable to start their assignments, but six medical residents interviewed by The Associated Press say they’ve undergone years of training and work only to be stopped at the finish line by what is usually a procedural step.

“I don’t want to give up,” said a permanent Canadian resident who matched to the University of Pittsburgh Medical Center Harrisburg but had her visa denied because she is a citizen of Afghanistan. She requested to remain anonymous for fear of reprisal. “But the situation also seems so helpless.”

Initially, the medical community was worried that hundreds of positions — many in hospitals in low-income or rural areas of the United States — could be affected. The pause on interviews for J-1 visas for approved work or study-related programs was lifted in mid-June.

The national nonprofit that facilitates the residency match process said the visa situation is resolving, but it will take weeks to know with confidence how many medical residents have had the start of their careers derailed because they got their visa too late or were blocked by the travel ban on 12 countries, according to people who coordinate the residents’ training.

Four foreign medical residents told the AP that U.S. embassies have been slow to open up interview slots, and some have not opened any.

“You lose out on the time you could have used to treat patients,” said one resident from Pakistan, who matched to an internal medicine program in Massachusetts and requested to remain anonymous for fear of reprisal.

The United States is projected to face a physician shortage in the next 11 years, per the Association of American Medical Colleges, and foreign medical residents fill critical gaps in the health-care system. More than 6,600 foreign-born international medical residents matched into U.S. programs in 2025 — the highest on record — and another 300 filled positions that were vacant after the match process was complete.

Not all of those residents were affected by visa issues or the travel ban on foreign nationals from countries including Afghanistan, Haiti and Sudan.

International medical graduates often take jobs in places where U.S. medical trainees tend not to go, said Donna Lamb, president of the National Resident Matching Program.

“It’s not just that they’re coming in and they want to work in big, flashy centers on the coast,” Lamb said. “They’re truly providing health-care for all of America.”

Foreign medical residents work in specialties to which U.S. applicants aren’t as eager to apply. For example, international candidates make up almost 40 percent of residents in internal medicine, which specializes in the prevention and treatment of chronic conditions such as diabetes and heart disease.

“The residents are the backbone of the entire hospital,” said Dr. Zaid Alrashid from Brookdale University Hospital and Medical Center in New York, which has medical residents from almost every continent. Most received their visas prior to the pause but a few were caught up in delays.

In California, leaders at two graduate medical education programs said they have a small number of residents caught up in J-1 visa delays. Both spoke on condition of anonymity due to concerns for the doctors who are still trying to get visas.

A residency leader at one large health-care system said two doctors in its 150-resident program are delayed, adding they could start late or defer to next year. A 135-person program at a California public health system told the AP that one resident has yet to arrive, though he was finally scheduled for a visa interview.

“We are not going to breathe easy until he’s here in our hospital,” the second leader said.

Lamb said her matching program had received fewer than 20 requests to defer or cancel residency contracts.

Worried about losing their spots if they defer, many foreign medical residents may keep trying to get to the United States and start their residencies late, said Dr. Sabesan Karuppiah, a past member of the American Medical Association’s International Medical Graduates Governing Council and former director of a large residency program.

Some hospitals may struggle at this point to replace the residents who don’t make it, leaving fewer people to care for the same number of patients, said Kimberly Pierce Burke, executive director of the Alliance of Independent Academic Medical Centers.
