Question: I am just wondering which agency to use to apply for my Iranian Visa. I finally decided to use www.uppersia.com.
Answer: For Iran visa 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.
