Medical Professions in Norway

I visited Norway once about a year ago and fell in love with the natural beauty, the culture, and the people there. I'm a college student from the US, planning on going to medical school and becoming a doctor (of course), and have dreamed about living in Norway. My girlfriend is a nursing student and will have her nursing degree in a few years. We would both consider moving to Norway, but we are concerned about the state of our future career plans and how difficult it might be to get a job in the Norwegian healthcare system after being educated in the US system. Any additional input about medical school in Norway would be awesome as well.

My question is, does anyone know how medical/nursing licenses would work as far as transferring from the US to the Norwegian healthcare system?
