I seriously doubt we'll be kicking out Non-UK nationals, that would sicken me if that happened.
How i see this, it's something the UK voted for and i respect that. Checking news media, and this UK referendum could spell other EU countries holding referendums themselves. I think they were holding out to see what our result was, and now this could give them the edge they need to do their own vote.
I went to bed last night with the headlines reading "potentially UK remains in EU", wake up to read "UK votes to leave the EU". This is historical, and only time will tell what happens and how the UK will fair.
