To communicate with the American citizen community in Oman in the most efficient manner, especially during emergencies, the U.S. Embassy in Muscat requests all American citizens, whether visiting or residing in Oman, to register their presence using the Department of State’s convenient online system By registering, you will be able to receive warden messages directly via email.  It also helps the Embassy better assist you in the event of an emergency.  If the timing of your trip or your contact details change, you can update the information on the website.  Please take a moment to register your presence – or to update your information – by visiting this website.
