Yep, just reapply for US MD or DO programs, whichever you think you'd be happier in, not whichever you think you have a better chance getting into.
All US MD grad will get a residency spot of some kind (although they may have trouble with the super-competetvie feilds, they will have a job in the US when they finish), provided they pass the USMLE (national boards), which 95% do on the first try. I don't know much about DO programs, but assume their success rate with getting residencies is similar.
If you go to of foreign school, on the other hand, they all have lower than 95% pass rates, maybe b/c their cirriculums aren't as uniform as the US schools. And you will be working your tail off sweating it till the last minute of match wondering if you will get a US residency. I have friends at the Carib. schools and they are much more uneasy about this whole match thing than i am now, b/c I know I will get a spot and they dont', despite they fact that I'm sure they worked just as hard as I did during med school.
