US urges Americans to leave Iran immediately as diplomatic and security tensions between Washington and Tehran intensify, prompting a renewed warning from senior US officials about the safety of American citizens in the country. The message, delivered by the US Secretary of State, underscores growing concern in Washington over detentions, regional instability, and the possibility of further escalation.
In a strongly worded statement, Marco Rubio said that no American should travel to Iran under any circumstances and urged those already in the country to leave without delay.
“No American citizen should travel to Iran for any reason,” Rubio said. “We reiterate our call for any American currently in Iran to leave immediately.”
The warning reflects longstanding US concerns over the safety of its citizens in Iran, where diplomatic relations between the two countries have been severed for decades. Americans traveling to Iran face significant risks, including detention, limited consular access, and restrictions on movement.
According to the US State Department, Iran has repeatedly detained foreign nationals and dual citizens on charges that Washington considers unfounded. These cases, officials argue, are often used as leverage in broader political disputes.
The latest advisory signals a shift from routine caution to an urgent call for departure, highlighting what US officials see as an increasingly dangerous environment.
Rubio said the administration has formally designated Iran as a State Supporting Unlawful Detention, citing both executive authority and recent congressional action. The designation follows an executive order issued last fall by Donald Trump aimed at protecting US citizens detained abroad.
“President Trump issued the Executive Order Protecting U.S. Citizens from Unlawful Detention Abroad last fall, and Congress has passed the Combating Unlawful Detention Act of 2025,” Rubio explained. “This authorizes the Department to designate Iran as a State Supporting Unlawful Detention.”
The designation allows the US government to apply additional diplomatic, legal, and economic measures against countries accused of detaining Americans without due process.
Rubio warned that further steps could follow if Tehran does not change its behavior. Among the measures under consideration are new geographic travel restrictions on the use of US passports related to Iran.
“If Iran does not stop, we will be forced to consider additional measures,” he said, “including proposed geographic travel restrictions on the use of U.S. passports to, through, or from Iran.”
Such restrictions would mark a significant escalation, potentially limiting Americans’ ability to travel even indirectly through Iran and reinforcing Washington’s effort to discourage all non-essential contact.
The State Department’s warning comes as US defense officials stress that diplomacy remains the preferred path, but not the only one. Pete Hegseth said the US is maintaining a full range of options in its approach to Iran.
Speaking to reporters during a visit to Colorado on Monday, Hegseth emphasized that Washington wants Tehran to return to negotiations and reach an agreement.
“Iran must make a deal. Iran has the opportunity to make a deal,” he said. “That’s the outcome the president prefers.”
However, Hegseth made clear that the US military is prepared for other scenarios if diplomacy fails.
Hegseth said his role, as defense secretary, is to ensure that President Trump has credible options available should talks with Iran collapse.
“My office is tasked with providing a range of options,” he said, “including having options available to the president if Iran decides to reject the deal.”
When asked directly whether a military strike remained a possibility, Hegseth replied bluntly: “Everything is still an option.”
That statement, while carefully worded, reinforces the message that Washington is not ruling out the use of force, even as it continues to emphasize negotiation.
The combination of travel warnings, legal designations, and military signaling reflects a familiar US strategy toward Iran: applying pressure while leaving the door open to talks. Supporters argue this dual-track approach increases leverage, while critics warn it risks miscalculation.
Analysts note that public warnings urging Americans to leave Iran often coincide with periods of heightened tension, whether related to nuclear negotiations, regional conflicts, or disputes involving US allies.
By urging Americans to depart immediately, Washington is also reducing the risk that US citizens could become bargaining chips in any future crisis.
For Americans with family ties, academic interests, or humanitarian work connected to Iran, the warning presents difficult choices. Many dual nationals have historically traveled despite advisories, citing personal or cultural obligations.
However, US officials stress that dual citizenship does not protect individuals from detention or legal action under Iranian law, which does not recognize dual nationality.
The State Department has repeatedly said its ability to assist detained Americans in Iran is extremely limited due to the absence of diplomatic relations.
The renewed warning also comes amid broader instability in the Middle East, where tensions involving Iran, Israel, and US forces have increased in recent months. US officials have accused Iran of supporting armed groups across the region, while Tehran denies involvement in actions that threaten American interests.
In this context, travel advisories are part of a wider effort to shield civilians from becoming entangled in geopolitical confrontations.
Beyond protecting citizens, the message that the US urges Americans to leave Iran immediately also serves as a diplomatic signal to Tehran. It underscores Washington’s view that Iran’s conduct — particularly regarding detentions — has crossed a threshold requiring formal consequences.
By invoking both executive authority and bipartisan legislation, Rubio emphasized that US policy on this issue enjoys broad political support.
While the immediate focus is on citizen safety, the longer-term trajectory will depend on whether Iran responds to US pressure by easing detentions and re-engaging diplomatically. If not, additional sanctions, travel limits, or other measures could follow.
For now, the administration’s message is clear and unambiguous: Americans should not travel to Iran, and those already there should leave as soon as possible.
As tensions persist and diplomatic channels remain uncertain, the warning highlights the precarious position of civilians caught between rival governments — and the lengths to which Washington is willing to go to prevent its citizens from becoming casualties of a deepening standoff.
