Question:

I am holding Canadian Passport. What I understand is that I have to apply visa number through this travel agent www.uppersia.com. Will Iranian Embassy in Istambul accept applicant who is not resident of Turkey?

Answer:

The Canadian  visitors of Iran should take part in a tour and be accompanied by a tour guide to travel in Iran and accommodate in the hotels.
In the visa application form the MFA should be informed about the hotels and itinerary in Iran. After having the reference number, the visa can be collected in two working days by direct referral or in one working week by posting the docs to the Iran embassy.
You should hire your guide or take the tour from the agency which applies for your visa. Moreover, the same agency should book your hotel as well, so it is better to take your all inclusive tour from that particular tour operator.
