England look only at home talent.
The RFU's chief executive John Steele has written to all England internationals and their agents warning of the repercussions should they play their trade outside the Aviva Premiership.
In the letter, Steele writes: "As things stand today we have a number of elite players in various squads and clubs outside England, principally in France, and you may be considering that as your next career move.
"If that is the case then I wanted to let you know that it is our view that we are best served by having our England Elite Player Squad (EPS) and our England Qualified Players (EQPs) all playing in England at English clubs.
"I would like to confirm that it is our strong intent, from the end of Rugby World Cup 2011 through the RWC 2015 cycle, to select our Elite Player Squads at all levels entirely from players playing at English clubs where at all possible.
"I would stress that this is not a change to our selection policy itself, players remain entirely free to play outside England should they so wish, but you need to understand that it is our absolute intention that we only select from overseas clubs in exceptional circumstances."
