The United States has issued an urgent warning advising its citizens in Iran to leave the country immediately, citing escalating tensions between Washington and Tehran and growing security risks.
In an advisory released on Thursday by the Virtual US Embassy in Iran, American nationals were urged to prepare departure plans that do not rely on assistance from the US government, warning that unrest and travel disruptions could worsen.
“Leave Iran now. Have a plan for departing Iran that does not rely on US government help,” the advisory stated.
The warning comes amid heightened strain in US–Iran relations, which have remained hostile since Iran’s 1979 Islamic Revolution and the subsequent US embassy hostage crisis.
Tensions have intensified in recent weeks following threats by US President Donald Trump to take military action against Iran over its crackdown on widespread protests that began in late December 2025.
Trump has also announced the deployment of what he described as an “armada” to the Gulf region, including the aircraft carrier USS Abraham Lincoln and its escort vessels, which have been stationed there since late January.
According to the advisory, US citizens in Iran should expect continued internet outages and prepare alternative means of communication.
Americans were advised, if it is safe to do so, to consider leaving Iran by land through neighbouring countries such as Armenia or Turkey.
The advisory also warned of possible flight cancellations and disruptions occurring with little notice, urging travellers to check directly with airlines for updates.
For those unable to leave, the US government advised finding a secure location, stocking essential supplies such as food, water and medication, avoiding demonstrations, keeping a low profile, and remaining alert to their surroundings.
“Monitor local media for breaking news. Be prepared to adjust your plans. Keep your phone charged and maintain communication with family and friends to inform them of your status,” the advisory said. It also encouraged US nationals to enrol in the Smart Traveller Enrollment Program (STEP) to receive security updates.
Washington further advised US-Iranian dual nationals to depart Iran using Iranian passports, noting that Iran does not recognise dual citizenship and treats such individuals solely as Iranian citizens.
The advisory warned that US nationals face a significant risk of questioning, arrest or detention in Iran, adding that merely showing a US passport or demonstrating links to the United States could be grounds for detention by Iranian authorities.
It also cautioned that the US government cannot guarantee the safety of its citizens who attempt to exit Iran through land borders.
The warning underscores growing international concern over Iran’s internal situation and the broader risk of confrontation between Tehran and Washington.
