There have been some recent IMG threads, read them.
The basic gist is that although not impossible the odds are severely stacked against you no matter how stellar your USMLE/grades. There are just too many qualified US grads for places to "take a chance" on IMG's, no matter how many accomplishments you have. If you really wanna do it, go for it, but you should go in with a realistic picture of the struggle ahead of you.
Good Luck
