21 Countries With "Do Not Travel" Warnings: What You Need To Know

19. Iran: Repressive Climate and High Risk of Arbitrary Detention

Iran's internal political climate remains highly repressive in 2025, and its fraught relations with many Western nations translate into extreme risks for foreign visitors, especially dual nationals. "Do Not Travel" advisories are primarily driven by the well-documented practice of arbitrary arrest, detention, and interrogation of foreigners on vaguely defined espionage or national security charges, often without due process or consular access. The risk of being used as a political pawn is significant. Civil unrest can also occur, met with harsh state responses, adding to the dangers.
