NY Doctor Stuck in Sudan After Trump's Immigration Order

Dr. Kamal Fadlalla is a resident at Interfaith Medical Center in Brooklyn.

Dr. Kamal Fadlalla, a resident at Interfaith Medical Center in Brooklyn, was supposed to return to the U.S. from his native Sudan on Sunday, his friend and colleague Dr. Menzin Khalid told ABC station WABC on Monday.

"He went home to visit his family. It had been a year and a half since he had seen his mom and his sister, so he thought now is a good time to go visit them," Khalid said.

Khalid said Fadlalla called him on Sunday and said, "I got my boarding pass to New York, and then I was informed by the airline company that my name has been called and I am not allowed to go."

Fadlalla is one of many who suddenly found themselves stranded in other countries over the weekend.

In a post on its Facebook page, the Committee of Interns and Residents at Interfaith Medical Center said it was rallying in support of Fadlalla. Members posted pictures of themselves holding colorful signs reading, for example, "No immigrant deserves discrimination" and "Immigrants keep hospitals running."

The CIR is a union that represents more than 14,000 interns, residents and fellows, according to its website.

"Other members are now unable to leave the U.S. to visit family in their home countries," the group said. "These laws are inhumane and unacceptable and cannot continue."

Khalid echoed the union's sentiments, saying, "I have the same thing. We are all pursuing a dream. We are all doing the best we can to improve ourselves and to do our best by our patients."
