Travel Warning
United States Department of State
Bureau of Consular Affairs
Washington, DC 20520

Iran
November 22, 2004
The Department of State continues to warn U.S. citizens to carefully consider the risks of travel to Iran. Due to ongoing tensions, particularly along the border with Iraq, U.S. citizens may be at higher risk of harassment or kidnapping. This Warning is being reissued without change after periodic review and supersedes the Travel Warning for Iran issued May 14, 2004.
Tensions generated by the current situation in Iraq have increased the potential threat to U.S. citizens and interests abroad posed by those who oppose U.S. policy. Some elements of the Iranian government and population remain hostile to the U.S. American citizens may be subject to the possibility of harassment or kidnapping. Some areas of the country, including the Baluchistan border area near Pakistan and Afghanistan, the Kurdish northwest of the country, and areas near the Iraqi border are not considered safe.
Large-scale demonstrations have taken place in various regions throughout Iran over the past several years as a result of a sometimes volatile political climate. U.S. citizens who travel to Iran despite this Travel Warning should exercise caution.
The U.S. government does not currently have diplomatic or consular relations with the Islamic Republic of Iran and therefore cannot provide protection or routine consular services to American citizens in Iran. The Swiss government, acting through its Embassy in Tehran, serves as protecting power for U.S. interests in Iran. Neither U.S. passports nor visas to the United States are issued in Tehran. The Iranian Government does not recognize dual citizenship and generally does not permit the Swiss to provide protective services for U.S. citizens who are also Iranian nationals. In addition, U.S. citizens of Iranian origin who are considered by Iran to be Iranian citizens have been detained and harassed by Iranian authorities. Former Muslims who have converted to other religions, as well as persons who encourage Muslims to convert, are subject to arrest and prosecution.
