Hi,
I just put a few words into google...
You need to contact the board of the state, where you will later want to apply for your license. They will be able to give you information, about whether or not (and in the first instance - which ones) they accept foreign degrees.
Try here for New Jersey: New Jersey State Board of Physical Therapy Examiners
Or here for all the boards in the US: https://www.fsbpt.org/LicensingAuthorities/

Good luck,
Fyzzio
