The U.S. Department of State issued a worldwide caution advisory, urging Americans traveling abroad to exercise increased vigilance amid rising geopolitical tensions.
In a security alert published March 22, the agency warned that U.S. diplomatic facilities and American interests overseas could be potential targets, particularly by groups supportive of Iran.
The advisory applies globally but emphasizes heightened caution in the Middle East. The State Department also warned travelers to prepare for potential disruptions, including periodic airspace closures that could affect international flights. Americans overseas are encouraged to monitor guidance issued by their nearest U.S. embassy or consulate and review destination-specific travel advisories before departure.
The agency also urged travelers to enroll in the Smart Traveler Enrollment Program (STEP) to receive security updates and alerts from U.S. embassies while abroad.
The warning comes as some Americans already report feeling uneasy about traveling internationally. A February survey by shipping company Send My Bag found that 44% of Americans aged 18 to 45 say they have lied about being American while traveling abroad, with some citing concerns about political tensions or unwanted conversations about U.S. policy.
Officials advise travelers to stay aware of their surroundings, follow local guidance and keep up with the latest alerts through official State Department channels.
