Hi, I'm a French physio.

In France, you can work in hospital, clinic, private practice (most of the French physio like me)...
To work as a physio in France, you must hold a registration. I think you'll have to proove your level of French and then you'll probably have to take exams (practical and theorical). You should contact the French Physio Board called "Conseil de l'Ordre des Masseur-kinésithérapeutes" to have further detailed informations.

In France, you're not only a physio but also a massage therapist... It's the same diploma.

I hope it will help you. If you have more questions, you can ask me and I'll try to answer it even if my english is not perfect!
