Hi Nico !
Unfortunately due to UK membership of a so called economic union of European countries called the EU employment in Britain of non EU nationals is severely restricted. If you happened to be an illiterate peasant from a feral Balkan nation you would be free to live and work within the UK without any restrictions. You and your family would be housed, educated and their healthcare taken care of thanks to the British taxpayer. It wouldn't matter if you were a convicted criminal the red carpet would still be rolled out.
It is beyond belief that decent people like you who could benefit Britain are kept out whilst the scum of the earth are allowed in without hindrance and paid to be here.
Good luck to you
