On Sunday, March 22, 2026, the U.S. State Department issued a rare Worldwide Caution security alert, advising all Americans traveling abroad to “exercise increased caution.” The notice cited “increasingly tense geopolitical situations” and warned that groups supportive of Iran may target U.S. interests, diplomatic facilities, and locations associated with Americans globally.
This alert follows the escalation of hostilities in the Middle East over the last month. Officials specifically warned of “periodic airspace closures”—particularly affecting major transit hubs like Dubai, Doha, and Abu Dhabi—which have already caused significant flight disruptions.
The “Do Not Travel” List (Level 4)
As of March 27, 2026, the State Department classifies 22 countries under its highest warning level, Level 4: Do Not Travel. Travelers are warned that the U.S. government has “extremely limited ability” to provide emergency services in these locations.

| Iran | Terrorism, Civil Unrest, Wrongful Detention, Kidnapping |
| Russia | Terrorism, Harassment by Security Officials, Arbitrary Enforcement of Law |

Additional Level 4 countries include Belarus, Burkina Faso, Central African Republic, Iraq, Lebanon, Libya, Mali, Niger, Somalia, South Sudan, Sudan, and Yemen.
Specific Regional Escalations
The State Department has also updated guidance for several key regions due to recent security incidents:
- Turkey: On March 9, 2026, the Department ordered the departure of non-emergency personnel from Consulate General Adana. Americans in Southeast Turkey are “strongly encouraged to depart now” due to the risk of terrorism and armed conflict.
- Israel & West Bank: Currently at Level 3: Reconsider Travel. Non-emergency government personnel were authorized to depart Mission Israel on February 27, 2026, following increased safety risks.
- Egypt: While generally a Level 2 destination, specific areas like the Sinai Peninsula and the Western Desert remain designated as Level 4 (Do Not Travel) due to military zones and terrorist activity.
Guidance for Americans Abroad
Secretary of State Marco Rubio ordered an immediate security review of all U.S. embassies last week. For those currently overseas or planning travel, the State Department recommends:
- Enrolling in STEP: Register with the Smart Traveler Enrollment Program (step.state.gov) to receive real-time security updates.
- Maintaining a Low Profile: Avoid drawing attention to your nationality, especially in areas with high anti-U.S. sentiment.
- Contingency Planning: Draft a will and designate a power of attorney before traveling to high-risk zones.
