Bonjour saviboy
I'm afraid only a U.S. citizen may currently train in an a/c with MTOW >12,500Lbs registered in the U.S.
I believe that if you already hold a type rating you are allowed to continue operating that type if you hold an appropriate visa or a 'greencard' .
The FAA website contains more details , but essentially , this limits non-U.S. citizens to anything lighter than , but not including , a King Air !
