It's not easy.
The "regroupement familial" is only for Asawa and minor kids, see here: http://vosdroits.service-public.fr/p...s/F11167.xhtml
Most of the official infos are here (or accessible from here): http://vosdroits.service-public.fr/p...liers/N8.xhtml
My advice is that you discuss with the ANAEM agency (it's the ex OMI: Ofiice des Migrations Internationale). It's there where you will get the best answers on this.
Last possibility is to try to get a "visa de long séjour" (1 year max), but it will go thru ANAEM too.
Let us know the results. Anyway be sure it will be a long battle. Good luck!
