Get a two-weeks visa at the IKIA airport in Teheran

Im not sure about that, there has been conflicting info about it. You can definitely get a 7 days visa, and it should be easy to get an extension. http://iranianvisa.com/uponarr.htm

NO ! Australian citizens do NOT qualify for the on arrival visa ! So you'll have to get your visa beforehand in Australian at the Iranian embassy.

Austrian, not australian.

hi. i do not think there is a 2-week airport visa but i may call the airport immigration to find out.bye.

Salaam Amir agha!
A gentleman, who is a hotel manager has confirmed me that there is a 15 days visa on arrival for Iran starting with the 19.2. The Austrian citizens are also qualified to get this kind of visa.
would you be so kind as to call the immigration office and tell me how it is.

very grateful to you.

Austrian, not australian.
