How long is my visa valid for? Q: I got my visa to Iran today from Dublin and just wanted to ask about its validity. Dates are 30.01.2012 - 19.04.2012. Does it mean that I can stay 25 days in the country even if I enter Iran on 19.04.2012? A: Iran visa is usually valid for entry for 3 months from the date of issuance. In your case, you can stay for 25 days even if you enter on the last day (April 19). That date indicates its validity to enter.
