Upon receiving a Visa Authorization Code, the visa may be collected at one of Iran’s worldwide embassies and consulates prior to arrival or upon arrival at one of Iran’s international airports. Most nationalities, except American, British and Canadian passport holders, can also obtain their tourist visa upon their arrival in the form of a Visa-On-Arrival (VOA) at the airport without a prior application. Although this method is convenient for last-minute travelers, it does have a higher risk of rejection and tends to be more time-consuming.
