Entry to practice requirements in a country are often not straight forward and it probably is best to find out exactly what is accepted and what is not. And what Yelufem is saying re providing barriers to foreigners is a sad and cynical reality. Having a degree at one level in one country is not necessarily the same as in another country and having a clinical doctorate is not necessarily better. I know in my part of the world universities are under pressure to switch from an undergrad degree to a clinical doctorate to keep graduates competitive in the world and stop them getting locked out of working in countries such as the US. However it creates some real problems: massive increase in study years and cost to students. And our publicly funded health system will just not afford to pay such graduates at rates the will be expecting.
However for your own future gotfunk8 I think you should seriously consider going for a higher degree as you obviously want a ticket to travel
Yelufem, I am quite ignorant of Nigeria's physio education. How does the five year degree work?
