Why should immigration be a problem; nobody's suffered mass immigration more than the Welsh, a people whose natural language has been subjected to such an attack that many Welsh believe the enforced language to be their own! We know the adage about a pebble thrown into a pond, the Pagan Germans threw rocks, but eventually they settled down to become the Christian England we all know and love, immigrants originally but accepted since. Of course that's not the whole story because only a hundred years after England was created they had to accept their own immigrants from Normandy, another rock in the pool, until it in turn settled down and was forcefully accepted by the non-native Germanics and eventually the native Welsh. We are now in Europe, personally I've been European since my first memories in Cymru/Wales, I 've never understood English or whomever referring to Europe as a different entity. Immigration is a part of life, always has been, so long as the pond after the pebble is thrown is allowed to return to its previous normal state acceptable to all after the initial disruption.
