Job experience??

Hi. I'm a senior studying Nursing, in foriegn country.

I'll be graduating the college this winter.

The problem is, I don't want to work as a RN, but want to study more.

I want to get NP, PhD degree as soon as possible !!

Will the graduate school allow me to join thier course, even I don't have any job experience?

Is there any friends around you who enter graduate school right after the under-graduate course?
