Question: I read that it is required for LOI for Canadian citizen. So I applied my online. Then I went to Iran embassy website in Canada and it does not mention any thing about LOI. So I sent them email to enquire about LOI. I got my replied a week later. They told me that LOI is optional. Too bad, I already pay for mine. If you want to apply one, check the embassy first.
Answer: For LOI you should fill in the visa form on http://www.uppersia.com/Iran-travel-services/iran-visa.html, it takes about 10 working 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.
