Sorry for my stupid question, but I am kind of lost right now

I was accepted to the 1st professional phase of NY pharmacy school this year and actually I was thinking that to become a pharmacist in NYC I just need to get my PhD degree. But today I was searching internet and found all these forums etc about pharmacy internship. So during my next 4 years at a pharmacy school will I need to get that intern license and work as an intern? Or it's just for foreign students? of just if I want it for my own experience?

Thank you
