The U.S. government has issued a strong travel warning for Iran, urging American citizens not to travel there for any reason and instructing those already in the country to “leave immediately” amid escalating tensions with Tehran. The warning reflects growing concern over security and the risk of wrongful detention as political and military pressure in the region intensifies.

Secretary of State Marco Rubio designated Iran as a “State Sponsor of Wrongful Detention” and emphasized that American citizens are at increased risk of being detained by Iranian authorities, who have a history of holding U.S. nationals and foreign visitors as political leverage. Rubio said that if the situation does not improve, the U.S. may consider additional measures, including potential travel restrictions on U.S. passports to, through, or from Iran.

In his statement, Rubio made clear that no American should travel to Iran for any reason, and those in the country should depart as soon as safety allows. The advisory is part of a wider reassessment of regional security as diplomatic talks over Iran’s nuclear program face setbacks and tensions with the United States and its allies remain high.

The warning comes at a time when global travel advisories have increasingly urged caution. Several other countries, including those across Europe and Asia, have also advised their citizens to avoid or exit Iran amid fears of instability and potential retaliation linked to rising geopolitical conflict.

Because Iran does not recognize dual nationality, U.S.–Iranian dual citizens could be treated solely as Iranian nationals, complicating efforts to provide U.S. consular assistance. With limited diplomatic presence and heightened tensions, the U.S. government stresses that commercial travel routes should be used while they remain available to leave safely.

Travel advisories are expected to remain active as conditions evolve, and American travelers are urged to stay informed through official State Department channels and embassy communications
