<<I understand you need either the right to live and work in the EU or a working visa.>>
This covers it. Whilst people like actors and city bankers seem to be able to manage it, for mere mortals like us, it's almost impossible unless you have a family connection. It is even harder for us going west- the green card or US work permit is again virtually impossible to get. The only way to get into the UK is to travel under a truck and declare yourself a refugee- then you stay....with the other 1/2 million or so who get lost in our bureaucratic system and end up staying. You don't want to come here- the taxes will make you go crosseyed, healthcare is a disgrace, and however bad your politicians, ours are worse!
More people want to go in your direction than this!
