The U.S. Embassy in Ukraine warned that certain American–Ukrainian dual citizens might not be able to leave the country and advised them not to travel to the Eastern European country.
In a bulletin issued on June 5, the embassy in Kyiv said that Ukraine on June 1 removed an exception for dual citizens that “previously allowed certain Ukrainian males aged 18 to 60 to depart the country.” Previously, certain dual U.S.-Ukrainian nationals in that group could enter or depart Ukraine if they de-registered their registry in the Eastern European country and registered in the United States.
