One, never trust others. This is valid in the US just as much as for any other country.

Two, improve your French to the Best of your abilities. I had to fight tooth and nails with my friend to get her to speak to me in French regularly

Three, don't move to France for weak reasons. If you like the cuisine or the language you can easily replicate that in restaurants and cinemas near you. Or you may get Netflix for that. You need to have strong TNT proof reasons.

If you are from the US you may be interested in moving to New Orléans for a while before you do the next big step. But please pour l'amour de Dieu, dont move to France simply because the cuisine is very good you'll experience the Paris syndrome
