All the schools and universities in Saint-Étienne have buddy schemes. For example, at Université Jean-Monnet, the BuddySystem allows French students to mentor overseas students before and after they arrive in Saint-Étienne.

All you have to do is sign up online, completing your profile as accurately as possible so that you can find a buddy who is a good match for you.
