It's very hard to get a UK work visa normally (and getting a lot harder each year, like in the US), but if you are a HN type with a good tech, start-up, investor, or researcher career, they roll out the red carpet for you.

If you qualify, you get a 'Tier 1' visa where you can work at any company without sponsorship, change jobs at any time just like a citizen, or start your own company with no fear of your visa being tied to a job. You can become a citizen yourself in 5 years.

Various other European countries have similar programs with different requirements. Netherlands, Portugal, and Spain are common places that a lot of US people go depending on what options they have to qualify and where they want to be. Spain has a digital nomad visa right now that is easy to get.
