Would I need a work visa to get employment in the UK?
You can not get a work visa without an invitation to work from an employer and that employer needs to get a license to employ you by proving that no one in the UK or EU can fill the post. (You may not change jobs, if that employment terminates, you go home). Professional footballer, entertainer, for example. Journalists can get work permits under the freedom of the press act. If you own your own business in the UK, that is fine too. Or you are the sole representative of a company with a branch in the UK. Your wages are paid by that company in your own country’s payroll. You can get a student visa and that will allow you to do some work. Otherwise you might find illegal work, usually not the sort of thing decent people want to do. If you get my meaning. Any one employing an illegal faces a heavy fine and a possible jail sentence. So your employer would have an illegal operation and you may go to prison too and then get deported. There are scammers who will promise you a visa in exchange
