depending in which state you are applying to. You will have to have your credentials evaluated by one of the agencies (FCCPT is a common one, that's recognized by most states). If you don't have a Green Card, you will have to file for Type I with FCCPT (go to their site Foreign Credentialing Commission on Physical Therapy and read about it). Everything is explained in detail there. If your degree is 3 years and you don't have any other (non PT related degree, for instance), then you will most likely lack credits in General education (science, history, literature, biology, physics, chemistry, etc.). Most states require 60 general credits and 90 professional credits.Good luck
