US passport holders need a visa to enter Iran and must travel with a licensed Iranian tour guide or organized tour for the entire duration of the stay. Independent travel is not permitted for US, UK, or Canadian citizens. Apply through an authorized Iranian travel agency, which submits your visa application to the Ministry of Foreign Affairs. Once a reference number is issued (10 to 30 working days), collect the visa stamp at an Iranian embassy or consulate. The visa fee for US citizens is $160 to $230 depending on the issuing consulate. Passport must be valid for at least 6 months beyond the date of entry.
Your tour operator arranges the reference number, itinerary, and guide. The guide accompanies you at all times during the trip. At Imam Khomeini International Airport (IKA) in Tehran, your guide meets you after immigration.
