I received my Iranian visa two days ago. My plan was to go there for a week, but unexpectedly I have an extra week available (due to an event in Turkey being cancelled just recently). Therefore I would like to extend my stay in Iran - to be precise enter the country before the date I put in my application. The itinerary would change a bit too.
Is this a problem? According to the date printed on it, my visa is valid for the entire period. Do I have to notify the embassy or the Police Department of Foreign Affairs or the party, I got my invitation from, about these changes?
What is the best way to handle the situation? I don't want to run into any problems, but I also don't want to miss the chance of spending some extra days there.
