I'm presently employed in France. I did a masters degree in France, and then applied for a residence + work permit and got a job in a large retailer. I don't have EU citizenship. My intention is to reside here permanently and apply for naturalisation (so, 2.5 years to go until I can apply for citizenship, 4 years until decision).
My broard field of work is operations research (the mathematical side of management science). I'm finding my employee status to be somewhat of a ball-and-chain around my ankle, in that the work I do could generate orders of magnitude greater value for both me and my employer/others if done as a startup or independent consulting business. The organisational dynamics of my employer makes me strongly doubt that we could come to an agreement on a "joint venture" vehicle.
Is there a titre de séjour for this sort of situation (a salarié wanting to go independent)? I've looked at compétences et talents and I almost certainly wouldn't qualify, not being a well-known entrepreneur or sports star.
