I am an Indian passport holder resident in Ireland.I am flying from Dublin (Ireland ) to Tehran (Iran). From what it seems, I think I may not have to apply for a visa in advance and get it at the airport itself in Tehran by paying 50 bucks? Is that correct? I read somewhere that the airline may deny boarding at the origin airport if they dont find a visa on my passport.
Yes you can fly to Iran and get a 30-day on arrival visa at the airport. This kind of visa is issued for 98 nationalities excluding USA, England, Canada, Colombia, Pakistan, Afghanistan, Iraq, Jordan, Bangladesh, and Somalia. If your nationality is among the countries authorized to get it, you can collect your visa against offering your passport, a passport-size photo and about 10-150€(depends on the nationality) to the staff at the airport. There is no need to fill in any form beforehand.
But the best option is to fill in the visa form on Iran visa application, it takes about 3-7working days to get your reference number and two working days to collect your visa at the embassy by direct referral or one working week by posting the docs to the embassy. You can pay the visa fee in cash in Iran.
