TS, don't hold your breath about working in France! I could be wrong, but I suspect that the other side of the Channel is about the only place in Europe where your shiny new ESAR-5 licence is NOT valid (and before Bookworm or somebody else puts me right, the licences are not strictly interchangable between states anyway).
Citizenship: remember, if you are an EU citizen (or an EFTA/EEA citizen) you have the right to live and work in any member state, although I'm sure the French will have found a way around that.
