I am a pharmacy graduate from India and a Canadian national. I passed my FPGEE Examination and hold a Intern Pharmacist License from Michigan Board of Pharmacy. I have been twice denied TN Visa saying I don't have Pharmacist License from US or Canada. I have been advised by the officer to apply for H1B visa. Recently, I read on State Department Website that License is not a prerequisite for YN visa. But my TN visa request was refused.
NAFTA clearly implies that you do not need a license (if you work under a licensed pharmacist).
Pharmacist—baccalaureate degree, licenciatura degree, or state/provincial license.
