Hello, my name is Bruna, I am looking into nursing schools in the U.S, Canada and Spain, but I wanted to know how is the working field in these places. I know a little bit about how's in the United States, you get a good salary and the job is recognized, the nurses are not the doctor's assistant (someone correct me if I'm wrong). This has been a difficulty in my path, if someone can help me I would really appreciate it. Also if someone know integrated schools in the U.S. (pre-nursing and nursing, one application), and not expensive schools in these places, for an international student.
