Traveling Abroad?

Ok so im fresh out of high school and will be starting college this summer quarter and i know i want to go into nursing because of the seduction of travel, one of my biggest hopes of accomplishing in my life and i plan to do so through nursing but im not sure what requirements i need to meet in order to do so. So i was wandering what i need to do as far as school is concerned to meet international standards or better yet what do i need to reach in nursing as far as certification to make my dreams happen and how much time will it take me to accomplish this roughly. Also any resourses you can throw my way ex. websites, info, etc. please do so.


thanks
