(IRAN) — The U.S. State Department kept Iran under a Level 4: Do Not Travel advisory and urged U.S. citizens in the country to leave immediately amid an ongoing conflict involving U.S. military operations there.

The advisory, the State Department’s most severe warning, cited risks of terrorism, civil unrest, kidnapping, visa revoked despite dropped charges”>Doroudi Stirs Concerns”>wrongful detention and arbitrary arrest of U.S. nationals. It highlighted a heightened risk for dual U.S.-Iranian citizens and said U.S. government assistance is limited.

Officials flagged detention-related concerns as central to the warning, pointing to wrongful detention by Iranian authorities and routine delays in consular access. The advisory also warned of unpredictable enforcement of local laws, with dual nationals singled out for extra scrutiny.

The warning sits alongside broader U.S. government messaging tied to the conflict, which the State Department described as involving U.S. military operations in Iran. The department also issued a worldwide travel caution warning that U.S. military strikes on Iran could cause global disruptions.

State Department guidance said the Level 4 designation and its core risk indicators have not changed in the latest update. That continuity matters for travelers weighing whether the security situation has improved, because the U.S. government kept the same highest-level warning in place.

Beyond the general security threats, the advisory described the possibility of harsh treatment following detention, including torture and imprisonment on charges like espionage. It also warned of kidnapping and hostage-taking targeting U.S. nationals.

For dual U.S.-Iranian citizens, the advisory stressed both the risk profile and the limits of U.S. assistance once a person is in Iranian custody. The State Department warned that consular access can be delayed, constraining the ability to provide help in detention cases.

The advisory also addressed maritime travel and port-related risks, tying them to broader security concerns. A U.S. Coast Guard warning advised mariners and passengers against travel to Iran ports due to ineffective anti-terrorism measures.

Vessels arriving from Iran face additional U.S. entry conditions, the Coast Guard warning said, creating a potential knock-on effect for commercial and passenger travel that touches Iranian ports. The maritime notice added another layer of caution for travelers considering sea routes linked to Iran.

Recent State Department security alerts in early 2026 reinforced the same overall message, with a focus on land border crossings rather than any shift in advisory level. A February 5, 2026 security alert reiterated Level 4: Do Not Travel due to terrorism, unrest, kidnapping and arbitrary arrest.

A similar security alert dated January 12, 2026 also warned about land border crossings and repeated the Level 4 language. The alerts underscored that specific travel channels, including overland routes, remained a concern even without a change in the overall designation.

While the Iran advisory emphasized country-specific dangers, the worldwide travel caution pointed to possible disruptions beyond Iran itself. The State Department warned that U.S. military strikes on Iran could trigger periodic airspace closures affecting travelers.

Such disruptions can force flight reroutes and sudden operational changes, the worldwide caution said, potentially affecting travel plans far from Iran. The State Department also stressed that the broader caution does not automatically translate into new Level 4 designations elsewhere.

In its broader framing, the State Department said no other country-specific Level 4 advisories are tied directly to the Iran conflict in current data. Standard advisories apply elsewhere, including in high-risk areas like parts of the Middle East, but Iran’s warning was described as explicitly elevated due to the war.

The State Department warning also noted a practical limitation for Americans who might still consider travel: there is no U.S. Embassy in Iran. That absence narrows formal channels for assistance, a point the department paired with its emphasis on detention risk and limited consular access.

Officials urged U.S. citizens to check travel.state.gov for real-time updates, reflecting guidance that conditions can change quickly. The State Department messaging also pointed travelers toward paying close attention to border-crossing notices and transportation disruptions when planning routes.

The U.S. government’s travel and maritime safety communications, including State Department advisories and Coast Guard warnings, formed the basis for the latest guidance. The State Department encouraged travelers to consult the most current official notices as the conflict and related disruptions continue to shape travel risk calculations.
