Texas is the ONLY one up in the air right now. All other states have had AUC grads licensed there. Some are harder than others, just in terms of paperwork or red tape, yadda, yadda, yadda. AUC is specifically approved in CA, NY, and FL, which will cover the rules of most, if not all states.

I hear Penn is kinda sticky, they just require meticulous records-keeping about clinicals. Colorado is also notoriously hard for FMGs in general. I also heard Idaho was off-limits, but that they were just about to enact legislation that would nullify those problems.

AUC is not specifically barred from any state. Only Texas is questionable right now, and that is not just AUC itself, it is all Caribbean schools.
