Last time i checked, it didn't really matter if you had a JAA or an FAA license,
Oh I think it does. It matters greatly if you have the licence of one country but not the right to work in that country e.g. an FAA CPL(H) is pretty useless in the UK and I can't imagine my JAA CPL(H) would get me very far in the States.
