I'd hope to think most schools would not admit an international student in a state that didn't allow foreign residents to register as interns. Have you tried contacting the board to see if your student visa may be sufficient?
Out of curiosity, why don't you stay in Canada for PharmD? UToronto, UBC and UWaterloo have already shifted to entry-to-practice PharmD programs, and more schools are on the way. Btw, it is also wayyyyyy cheaper to stay North than going South. I am actually going back to Toronto in less than a month.
I asked because I am also a Canadian, with US permanent residence.
Two of my classmates are from Canada, and they didn't seem to have any issues. Both now are pharmacy residents here in the states. I am a dual citizen so it didn't apply to me. We also have international students from other countries that have their intern license and work.
