How difficult is it for an American to live in england? I mean would they need a visa of some type or a work permit? How difficult are these to obtain? I'd love to visit england someday but am of the understanding that being a us citizen that I could only stay from 3 to 6 months on my passport is this correct? Also is it true that if you stay for say 3 months and leave the country can you then return again shortly there after? I've heard in short that its very difficult for a uk citizen to migrate to the united state and vise versa,why is this the case?
