The U.S. State Department's Bureau of Consular Affairs (@TravelGov) reported that as of April 21, Iran's airspace has partially reopened. U.S. citizens should leave Iran now, monitor local media for updates, and consult with commercial carriers for additional information on flights out of Iran. Americans seeking to depart Iran may also depart by land to Armenia, Azerbaijan, Türkiye, and Turkmenistan. U.S. citizens should not travel to Afghanistan, Iraq, or the Pakistan-Iran border area. Be aware that the Iranian government may prevent U.S. citizens from departing or charge an “exit fee” for departures from Iran. U.S.-Iranian dual nationals must exit Iran on Iranian passports.
