This is an old topic so I am not sure who will see this...
I highly recommend the Peace Corps (www.peacecorps.gov
) and I am pretty sure that they always need nurses. Most of thier jobs are probably going to be education based, ie you will be teaching people hygene, self care, or you may do a project in something like HIV/AIDS awareness.
They are a great place to start if you have never been overseas. They take real good care of you, have great classes to teach you the language and the culture, and they will send you to the most incredible locations.
