The Royal Oman Police analyzes all the requests received by US citizens. The analysis is very swift. The vast majority of American applicants receive their eVisa within 2 working days.
If their Omani eVisa form has been correctly filled in, American nationals will receive a confirmation email, and the online visa will be automatically linked to their passport.
To account for busy periods during the tourist season, we recommend submitting their application for the eVisa at least 72 hours before their arrival.
Upon receiving the approved eVisa notification, it is also advised that US travelers print out a copy of the online visa and store it next to their travel documents before their departure.
