If you can back up your reasons for the dismissal, do better on Steps than the US mean, then I think you have a shot at matching somewhere in the US (probably psy or fm). Let's not forget that even at AUA, maybe around 10-15% of your classmates were from other schools (Ross or auc) as a transfer student because they also didn't make it at their first school, but these people do match. That said, no one here can say that you will match with a guarantee, but I think if you can back your problems through proof, do really well on steps, then you should match. Also, connections help a lot in these situations.
But the major problem I see, other than matching is, finding a school like AUA, that will take your credits. The only one I know that takes AUA credits is CMU. Good luck.
