Yes, it is possible to receive an airport visa for the citizens of about 180 countries and it is available now at Imam Khomeini airport in Tehran, Mehr Abad airport in Tehran, Mashhad airport, Isfahan airport, and Shiraz airport. Of course, we emphasize on not using an airport visa and obtain your visa before travelling, because it may take a lot of time at the airport due to busy crowd. We have cases whose airport visa has been delayed for 24 hours.
