Iran

From Visawiki - the Collaborative Guide to Visas

Iran is a country in Asia.

Your passport should not contain evidence of visiting Israel.

Iran has a visa-on-arrival program for several countries, but only when arriving in an airport.

If you want to apply for the visa in Turkey, as many people do, on the silk road, there are consulates in Ankara, Istanbul and Erzurum. But according to many people who have done that, it can be a huge loss of time, waiting weeks, and sometimes being refused (even if you have already paid!).

[edit] Get a visa in Trabzon, Turkey

Tip from a French traveler: There is a hidden consulate, in the city of Trabzon, north-east of Turkey. It doesn't appear on internet, but it exists. And there, it's possible to get a visa, in 3 hours, without any problems, without any questions. It worked for at some people: French, Belgian, German, and maybe others. It may be worth to ask there. About the Visa Application in Trabzon, Turkey : there is no need to ask a number at iranianvisa (which is some kind of legal scam). In Trabzon consulate, they ONLY want 2 photos, 60 euros, fill the 2 forms... That is ALL. No application number, no letter of recommandation, no hotel reservation... If they ask you where you go, you can tell the bigest cities, Tabriz, Tehran, etc. If they ask you how you will travel, just tell you go in those city then take a plane back or to the next country you already have a visa.

Your passport should not contain evidence of a visit to Israel.
