Starting a Career & Networking?

I'm a college student and I have some questions about starting a career and networking? I'm currently in my second year of what is a three year program for a bachelor's degree in Game Art Design. And I am overwhelmed and concerned with where to start and go after college. I know I want to work outside the states. I live here now only to finish college. For example, how do I go about establishing contacts / networking outside the country and also go about finding job leads. All I can think of is start off doing free lance work but then after that I just don't know. Anyone who responds to this, keep in mind that preferebly I would like to live in the U.K. as my first choice and then Canada as my second. After that it doesn't matter. I would greatly appreciate any advice on this matter.
