Moving to the U.K. from the U.S.?

I know I need a Visa to go there and I was wondering what the requirements for a Visa are? What will expenses be? Where are the cheapest places to live? What is the cost of living? How long will it take for me to be an official citizen? And anything else that I forgot. If anyone has been through this experience before let me know the pros and cons. Any help will be greatly appreciated.|||You have a few options for a visa1 - student visa. You have to first be accepted at a British university and show you have enough money to cover your fees and all other living expenses2 - Tier 1 visa requires a Masters or PhD, high salary and evidence of savings3 - Tier 2 Intercompany Transfer visa where your current employer transfers you to their UK office4 - Tier 2 Sponsored visa where you possess special skills that no EU citizen has. A company has to prove the position was advertised for a minimum of 4 weeks and not 1 qualified EU citizen could be found. This is almost impossible unless you are a scientist, engineer or medical professionalExpenses vary from £270 - 690 depending which visa category you fall under. The cheapest places to live are where there are no jobs. Cost of living in general is about 30-40% higher than the US. With the rule change next year, it will take 10 years of continuous legal living in the UK to become a citizen. Years spent as a student do not count towards this residency requirement
