Are Canadian Physicians competent to practice within the USA?

Without having to nick the USMLEs? You need to be licensed within the countries you're practicing in.
I would have a sneaking suspicion that that they would be able to because physicians from everywhere are competent to practice in the US. I reflect that they would have to nick the USMLE,though.
if their education is approved in the US and if they go by the boards in the US, yes.
