I'm an American citizen. I've been studying and living abroad for a couple of years, and now I want to go to France to study. Would I need a visa? And does anyone know the procedure?
Having been abroad in the past doesn't give you any special rights. If you want to go to France to study, you'll have to find a university or other place of education, apply, and, if you are accepted, go through the visa procedures [in French]. Universities have an administrative office that helps foreign students do that. They'll have all the information you need.
