Nursing in Mexico?

Hey fellow nurses, I need some advise. I've been a nurse up in Utah for the last couple of years and need to get out into the world. I'd love to go down to Mexico, or really any other Spanish speaking country. My concern is that my Spanish is pretty intermediate, I don't know if I'm really ready to be a nurse in Spanish but I'm trying to rack my brain on how I can make it work. I'm pretty poor, so I can't really afford a program that I have to pay for while I'm not earning any wages. If anyone has any words of wisdom or information I would greatly appreciate it. Thanks in advance.

Jill
