Same here. Unless you're really lucky and find a startup willing to sponsor you, your best bet is probably to do the H-visa thing at a big company until you can get a Green Card. Then you're free to have some fun, as long as you don't stay out of the country for longer than half a year.

That's the route my folks took, though from Germany, so it might be different for you (with per-country quotas and whatnot).
