How can a foreign physical therapist graduate become a physical therapist in the US?

I assume you are a foreign medical school graduate? First, make sure that your education is recognized in the US as being from an accredited institution.

If so, you would have to take and pass Part II of the National Boards. Then, you would be able to apply to numerous Medical School residency programs based on your field of interest. Seek counsel either from your medical school advisor or discuss the matter with an advisor at a Medical School near your home town. The programs that are looking for residency trainees are usually the primary care specialties (FP, GP, internal medicine, and pediatrics). We have too many sub-specialists in the medical field at this time.
