if you are under 35, you can get a J1 visa fairly easy. basically, they bring you over as a paid intern. your salary and real scope of work don't necessarily need to be of an intern
I did look at the J1 visa in the past, and as far as I remember it is a non-immigrant visa which basically allows you to work in the US for one internship, after which you will have to leave the country again. What I meant by “working in the US” was something like 2+ years (then there’s usually still the green card option).
usually you can stay beyond the internship and adjust your status to H1B, O1, F1, ... what you really need is a foot in the door and establishing your presence in the states. once you set your foot on american soil, it gets much easier. any visa is better than no visa
