Re: Speaking from personal experience
The fact that people could end up having to return to the UK, if there is an "out" result doen't even get a look in.
Why should EU countries grant or renew residency and work permits to non EU citizens?!
Should play well to the far right in many countries:
Damn British, coming over here, stealing our jobs, taking our child benefit....
Prepare for the tidal wave of returning expats!
I, for one, will be wanting my free house and benefits on arrival.
