Patient Maziar Hashemi (R), who has the cancer Myelodysplastic syndrome, and his wife Fereshteh leave after meeting with his transplant doctor at a hospital in Boston, Massachusetts, U.S., March 26, 2018. Hashemi's brother in Iran is a perfect match for a bone-marrow stem-cell transplant, but it is uncertain if his brother can travel to the U.S. from Iran for the procedure because of the travel ban restrictions.
