Throughout the entire EU and Immigration debate - NO one seems to have cottoned onto the fact that there’s pretty much bugger-all we can do about those immigrants already here.
Concentrate on “getting them integrated” then. Any attempts to deport them will only make more go underground.
We should concentrate on criminalizing ONLY those that are here illegally. That would be those that were not originally from the EU, but passed through the EU to become illegal immigrants to the UK.
Doesn’t anyone else on here talk to their long-standing immigrant colleagues - to hear them spitting blood at the “newcomers of now” that THEY cannot stand?!
Immigrants that have already been here 10-20 years or so have (1) Learned our language, (2) Pay our taxes, (3) Joined our institutions and even (4) Brought some unattached women of their own with them.
Now compare our Utopian immigrant friends to the dross that is near 0% unattached female, pay no bloody taxes at all, but somehow qualify for tax credits (EU edict) WON’T join our institutions, and even after having been here a while - play the “no speke English” card whenever they are asked anything awkward…
The pollsters are counting all immigrants as being “voters FOR staying in the EU”… They don’t even consider that the decent immigrants lose as much out of being in the EU as the rest of the workforce - and the fact that the “new arrivals” can hard be voting to stay in - if they’ve gone to ground, and are hiding from the authorities - can they?
The split is supposed to be neck and neck as it stands. I doubt that very much. The number of “stay in” votes has been grossly over-estimated with the above reasons I’ve given just being the tip of the iceberg.
The forthcoming referendum vote being denied to 16 & 17 year olds (the most affected by any changes here) speaks volumes too… Those youngsters who find they cannot get that job in the library, student bar, sweet shop, or other casual retail job anywhere - 'cos some jemile-come-lately got in there first are NOT going to be voting “Stay In”, so let’s push down the “anti” vote by denying them the vote eh? Great. 
The older generation are not really affected by any of this, and are most likely to vote in a “status quo” fashion, and sleepwalk us into “more of the same forever” - IF we don’t get out there and out-vote them instead!
