The US State Department has updated its "Level 3: Reconsider Travel" advisory for Oman, warning American citizens of ongoing risks from terrorism and armed conflict. The update, issued on 30 August, primarily changes the policy on family members of US government staff joining them in Oman, though the overall risk level and warnings remain unchanged. The advisory highlights concerns that attacks could occur with little or no warning, particularly around holidays, potentially involving knives, firearms or vehicles at locations frequented by tourists and foreigners.

The warning also cites the continuing threat of drone and missile strikes linked to Iran, following the outbreak of hostilities between the US and Iran in February, and advises against travel to the Yemen border area due to conflict risk. Despite the advisory, Oman's tourism industry has been expanding, with the country recording nearly four million visitors in 2025 and drawing interest for sites such as Nizwa Fort and Muscat's historic waterfront. Officials are encouraging any Americans who do travel to enrol in the State Department's Smart Traveler Enrollment Program, take out travel insurance and prepare an independent emergency evacuation plan. The Oman update follows similar recent advisories for Brazil and Ecuador, reflecting a broader wave of heightened US travel warnings.
