(CNN)An Iranian infant with a heart defect is entangled in President Trump's immigration ban -- and her extended family in Oregon is on an urgent mission to get her to the US for critical surgery.

Fatemeh's parents were scheduled to meet with doctors in Portland on February 5, but were barred from traveling from Tehran to Portland, Fatemeh's uncle, Samad Teghizadeh, told CNN Thursday.

Several congressional Democrats released a letter Friday evening asking for Secretary of State Rex Tillerson to grant a waiver for the child and her parents to come into the country for surgery.

Though the baby's heart surgery is still in limbo, New York Gov. Andrew Cuomo released a statement on Friday about the family being able to come to the US.
"This evening we were pleased to learn that the federal government has now granted Fatemeh Reshad and her family boarding documents to come to the United States," Cuomo said.

"We will continue to work with the International Refugee Assistance Project and their partners to ensure this baby receives the treatment she needs, and fight for those being unfairly shut out of America's gates by this policy."

Last month, Iranian doctors in Tehran told baby Fatemeh's family that the 4-month-old has structural abnormalities and two holes in her heart, but they lack the resources to treat the infant.

Fatemeh and her parents boarded a flight to Dubai on Saturday, but they were rerouted back to Iran and told to reapply for a US visa in 90 days.

Teghizadeh, a US citizen who lives in Portland, worries his niece will not make it until then.
