Hi Pullpowa,
The first thing to consider would be your french language level. If you are not fluent in french, don't think about finding a job in France.
Second thing, the licence conversion pocess is a really long and hard way in France (the french civil aviation is a real pain in the ass (sorry Flyblue
for that!!)
Maybe you should consider doing it in UK where it would be easier.
For further informations go and check the DGAC website (gdac.fr i think)
cheers!!
