As long as your intern license is valid, you should be OK to work as an intern. But, for example... if you are in between your 3rd and 4th year, and decide to take a few quarters off from school for whatever reason, my school said that you would have to surrender your intern license. I guess I'm not sure what your question is, I would contact my school to be absolutely sure about it. you don't want to end up working and then have those hours not count!
