If middle eastern people can move in here and open up corner shops and Polish people can move over and take over all the jobs, then yes it will be pretty easy for you to immigrate to here, call up some numbers and find out any information you need, write down any questions you can think of before calling. Also before ending the call, always ask them if there is anything else they think you should know.
You live in Germany, i dont see why you would want to move to the UK, Germany is a far better country, if you want to move, at least move to France, they are also a better country than the UK and just about as good as Germany. The top 3 countries in the EU from top to bottom are, Germany, France and UK. I wouldn't recommend downgrading. Me personally i want to move out of the UK and one day live in Japan or America. Good luck with whatever you decide.
