Visa would be a smart idea to travel anywhere but yes they do. Unfortunately in the public it is said that Iranians do not need visa, but according to my recent experience that occurred this month Jan 2012 they do need visa of Venezuela in order to travel to this country. I wanted to travel to Venezuela via Colombia but the Venzuelan police in the barrier of Colombia told me that Iranians as well as many other countries of Middle East such as Iraq, Lebanon, etc. need visa in order to travel to Venezuela. I think it is just an advertisement that Venezuela is doing to say to the world that it is a free country and it is a political trick! not more. So I suggest to everybody specially the Middle Easterns to assure about having a trip and journey to other countries in advanced in order to prevent the likely problems that they might have in their trip! Iranians Please Be Careful about what you hear. Many of them are not true. PLEASE SEARCH, ASK, QUESTION BEFORE YOUR TRAVEL TO ANY COUNTRY IN THE WORLD IN ORDER TO BE SURE ABOUT YOUR TRAVEL.
