Should you decide to travel to Iran despite the current Travel Warning, a passport and visa are required. To obtain a visa, contact the Iranian Interests Section of the Embassy of Pakistan located at 2209 Wisconsin Ave. NW, Washington, DC. 20007; tel 202-965-4990, 91, 92, 93, 94, 99, fax 202-965-1073, 202-965-4990 (Automated Fax-On-Demand after office hours).

The Iranian press has reported that foreign tourists may obtain seven-day tourist visas at the airport in Tehran. However, U.S. citizens are strongly encouraged to obtain valid visas in advance to avoid delays and/or interrogation, as well as to reduce the prospect of denial of entry at the airport. Note: possession of a valid Iranian visa will not guarantee entry into the country. Some American travelers with valid visas have been refused entry at the border without explanation.
