The easiest way is marriage to a citizen, I have no idea what sort of job skills someone would need and which visa they would need if it was through work. I was the other way, I did UK to the US with being married to a US citizen. I found settling into the US was pretty straight forward once I’d got my green card and my wife when she moved to the UK when we married settled in pretty well so you wouldn’t have any issues if you did move I think. If you’re young enough I’d say getting something lined up with education in college which could get you a job here could be a route. It might be worth seeing if there are any companies in the US with UK offices and seeing if they could let you move.
