<p>I think Cheers' question is very, very important: What do you want out of your time in France (or any other country)? </p>
<p>Once you answer this question, sorting through your options will be easier. If you want job experience, then a program that includes an internship would be the one to look for (or, as others have suggested, arrange to work abroad for a summer or semester). If you want specific knowledge about a subject from a different cultural perspective (i.e., EU economics), then you want to find a program and school that will let you take specific courses in that area. If improving your language skills is your main goal, than a progran that offers intensive language classes and the opportunity to take classes in the language should be what you're looking for. Do you want the chance to interact with people in the country beyond in the classroom? There are programs that emphasize service while abroad. And, there's nothing wrong with deciding that what you mainly want is a chance to just live in another country - I do think that is valuable and worthwhile in and of itself - but you may choose a different type of program if that's your main goal.</p>
<p>But, I'd start with Cheers' question and then go in search of programs and options. I know you well enough to know that you are very good at setting goals for yourself! :)</p>
