The U.S. State Department issued a worldwide caution on July 19, 2026, advising Americans traveling or residing overseas to remain vigilant due to potential threats from Iran or its supporters. This alert, in effect since February, highlights the risk of targeting U.S. citizens and interests globally, particularly in the Middle East. The advisory follows recent military actions, including an Iranian missile and drone attack in Jordan that resulted in the deaths of two American service members.
The U.S. Embassy in Amman has also issued a security alert, advising Americans to avoid the international airport and seaport in Aqaba due to a credible threat. The State Department has maintained an ordered departure for non-emergency personnel in Jordan since March due to ongoing security risks.
Officials emphasized the complex security environment and the possibility of escalated conflict. They urged Americans to exercise caution, keep a low profile, monitor local news, and follow guidance from U.S. embassies. The advisory also noted that military activities could disrupt commercial flights and lead to airspace closures, advising travelers to check with airlines for potential changes to their itineraries.
