Immigration?

Does anyone know anything about immigrating from the US to England? My friend knows somebody who wants to immigrate from the US to England, but doesn't know any of the requirements etc. Any help?

I'm going through UK to USA immigration right now.

Ahh thanks. Nah I cant imagine it is!
