If you have all the means to come here in the US and work as a nurse, you are very much welcome. However, if you are thinking about getting an employer sponsored working visa, I would suggest that you just hang in there until the US opens it's doors to foreign skilled nurses again. Unfortunately, there's not that much demand with nurses right now. Even US-based educated nurses have difficulty finding employment. Actually there is a surplus of nurses here in the US just to be honest.
