A newly graduated nurse on work permit (OPT)

Hello, I'm a newly graduated nurse with associate degree in nursing. I have just passed the board and currently waiting for my work permit to arrive. I studied at a college in Kansas, and I am kind of frustrated trying to find hospitals who hire foreign nurses. In other words, I need a hospital who sponsors international nurses to get work visa or green card. Do any of you have suggestions? Please? Every bit of it could help! Thanks!
