What state do you live in? I would start by looking at the 4 year schools that your junior/community college has articulation agreements with…that way you are certain your credits will transfer. Hopefully there would be an affordable situation there but you may have to go part-time and/or work as you go thru school (not sure the student visa allows this?). I would also research online schools (only legit, non-profit ones like ASU, Western Governor’s, Southern New Hampshire). Work with transfer admissions counselors at every school you consider…you do not want to lose credits when you transfer, which is very common if not paying attention.
The bad news is this: DPT school is long and expensive. If paying for your 3/4 years of college will be difficult, how will you pay for PT school? Even if you were to find a way, if you don’t have permanent residency (or certain visas) you will not be able to work in the US once you finish school (whether undergrad or DPT). Please identify your options, and think about what might be the best for you, as right now the immigration situation is difficult in the US.
