I'm a JAA/EASA ATP holder, and I live in the UK, problem is I have an American girlfriend who lives in Michigan, and i'm wondering how easy it is to move over to the USA for a flying career?!
After you marry the girl and with your JAA ATP converted to FAA you shouldn't have any problems getting a job here. The majors are hiring and the regionals are begging pilots to work there.
Major... around 30k-40k first year. On reserve for a few years. Get used to working on weekends. But after a year or two pay will dramatically increase.
Regionals... around 30k-40k first year. But expect to top out at around 40k as a FO. Captains can earn into six figures but only after ten years or so.
