I currently live in the UK in London, I would like to relocate to the USA?

Here is an honest answer. You do not say what your nationality is so I will presume you are British. It is simply impossible for a Brit to move to the U.S. To get a temporary work visa you must be highly educated, skilled , and experienced in a much needed job and find an employer to sponsor you. Always nearly impossible, and right now just plain impossible. To immigrate to the U.S. you must have an American relative to sponsor you. Period. there is no visa that will allow you to live and work in the U.S.Unemployment is high...no one wants or needs foreign workers. Immigration to the U.S. is harder than riding a bicycle to Mars...cannot be done. You need to look around for other options....like the E.U. You could not afford to live in Manhattan anyway...costs 4 times as much as any other city in the U.S. As to living "easily" in the U.S...wow!...most Americans are working as hard as they can ( IF they can find a job) and are barely managing to hang on. If you truly want a chance to live and work in the U.S for a year ( NOT N.Y.), see site below for a company that helps young people do that.
