hi,
I just called again the Imam Khoemini Airport Immigration and they finally were able to verify and confirm that both Irish and Australian citizens now in fact do qualify for and could receive the 15-day instant visa. Make sure you tell the Immigration officer when checking your passport, that Ireland is NOT part of UK. I am not kidding. The clerk i talked to had this weird notion that Ireland was still part of Great Britain, and had to get back to his boss before answering my question!
However, please remember this new instant 15-day visa is only intended for tourists and if you mention any other reason for coming to Iran (e.g, business, journalism, even learning Farsi) you will be denied visa. So keep this important fact in mind. Bye.
Withshoeson>>>> i think the airline should allow you on board. Also do an extensive search on both Iran Foreign Ministry English web site (Visa Section) and IK Airport to see what you can find. Get a print out and show it to the airline. good luck.
