The U.S. State Department has urged American citizens remaining in Iran to depart the country, issuing a formal alert on Wednesday following a partial reopening of Iranian airspace amid a ceasefire between the two nations.

The Bureau of Consular Affairs issued the warning as travel conditions began to shift, cautioning that despite the airspace reopening, significant risks remain for U.S. nationals attempting to leave.

The bureau specifically warned Americans to be aware that "the Iranian government may prevent U.S. citizens from departing or charge an 'exit fee' for departures from Iran," according to reporting by The Hill.

Ceasefire backdrop

The alert comes in the context of a ceasefire between the United States and Iran, though the State Department's guidance suggests the diplomatic situation remains volatile enough to pose direct risks to American civilians on the ground.

Iran's partial airspace reopening signals a de-escalation in hostilities, but U.S. officials have stopped short of indicating the situation is fully stable. The advisory reflects ongoing uncertainty about how Iranian authorities may treat departing American nationals during this transitional period.

Longstanding travel risks

The United States has maintained a longstanding "Do Not Travel" advisory for Iran, citing the risk of wrongful detention of U.S. citizens. Iran does not recognize dual U.S.-Iranian nationality, which has historically complicated consular access for Americans detained in the country.

The State Department has no embassy or consulate in Iran, meaning American citizens in distress have extremely limited options for official U.S. government assistance on the ground. Switzerland serves as the protecting power for U.S. interests in Iran in such circumstances.

What Americans are being told

The consular alert advises Americans who are able to leave to do so while commercial options are available, while also warning them to prepare for the possibility that Iranian authorities could impose financial or legal barriers to their departure.

The advisory does not specify the number of U.S. citizens believed to be currently in Iran, a figure the State Department rarely discloses publicly. However, a number of dual nationals and individuals with family ties to Iran are known to travel to or reside in the country.

U.S. officials have not provided a timeline for when the full airspace may reopen or when travel conditions might normalize, leaving the situation fluid for those seeking to exit.
