Bonjour Julien,
My name is Curie and I am a French national. I plan to return to France and I would like to apply for my social security number. I have never had one because I never worked in France and I lived abroad for a long time. I have la carte d'identite et le passport but I need a social security number to apply for benefits. Can you help me how and where to start first for apply this social securite number? Thank you Julien.
