In his speech at Columbia University, Iranian President Ahmadinejad invited university faculty and students "to come and visit Iran, to speak with our university students":

"You're officially invited. University faculty and students that the university decides, or the student associations choose and select are welcome to come. You're welcome to visit any university that you choose inside Iran. We'll provide you with the list of the universities. There are over 400 universities in our country. And you can choose whichever you want to go and visit. We'll give you the platform. We'll respect you 100 percent. We will have our students sit there and listen to you, speak with you, hear what you have to say. Right now in our universities on a daily basis there are hundreds of meetings like this. They hear, they talk, they ask questions. They welcome it."  (translation from the Washington Post)
