In order to receive a visa that permits you to work full-time is even trickier. See, you will need to demonstrate to the English government that you have a special skill or expertise that no one in England has. You are not allowed to take a job away from a person in the country that could manage working in the job. They too have unemployment problems and do not open their doors freely to anyone from outside the country to come in and take their jobs away.

So good luck with your plan. You will need to do some work evaluating your skills and deciding how to best go about getting your visa. I reccommend trying to get a job in the UK before you go there. If you have a company that is willilng to sponsor your visa application because they want to hire you, you have a much better chance of success. This is how I managed to secure my positions. Or you could marry an English person.

Good luck!
