I was in Iran in May and I am planning to go back in late August/September. I might need to apply for another tourist visa a few months later. Is there a limit to the number of visas you can get in a year? Is there a higher risk that my application is rejected? I will probably go through www.uppersia.com to get the MFA code as I did last time.
Your visa will not be rejected if you have tried once in the same year. After being issued, the visa is valid for a 3-month to enter Iran. So when you use the visa once, it will be expired and then you can apply for the next one. In the case of having Israeli stamp in your passport or being a journalist, the visa on-arrival may not be issued for you.
