IICQI-14 will be held in Isfahan, on September 2014. Isfahan is located about 340km south of Tehran. The city has an international airport (with flights from, e.g., Turkish and Qatar airlines), and is well-connected to Tehran. You can fly to Tehran's Imam Khomeini International Airport (IKA) and travel from there to Isfahan. If you want to stay in Tehran for a few days, the conference will provide accommodation for you in the IPM guest-house free of charge.
You will need a valid visa to attend the conference. According to the new regulations by the Iranian laws, tourist visa is issued in the airports of Tehran and Isfahan for maximum of 15 days for citizens of all countries except those from USA, Canada, and the UK. It is highly advisable that you first check with your airlines to make sure that you are allowed to board without having an Iran visa stamp on your passport. If you may need a visa before landing, please let us know well in advance. The organizing committee will make its best to assist you in your entry visa application, and will supply an official invitation letter (which is a required visa application document).
