How would someone go about moving to France?

I’m a citizen of France.
Born in America, still in America. But have a dual citizenship.
18 years old and wanting to go to college in France.
How much money will i need to go with and what will i need to do to move there?

Best reply by Eleni Papadopoulou:

In Paris, most of the Universities are public, therefore free. You can visit the sites of some Universities… But you REALLY need to speak french! They are not going to talk to you in english!
