Green card holder with BSc (applied physics)

In the near future my wife I hope to return to the United States from Ireland. After we enter the US I am hope to enroll in nursing school. Before then I would like to find out as much as I can about what exactly my options are, and I what I must do to gain admittance to a nursing school. Can I go straight into a BSN course,or must I first complete some prerequisite classes? Will my credits from my physics degree count towards a nursing degree?

Thank you,

Shawn.
I'm sure you will get some credit for the work you have already done, but you'll probably have to take some extra classes as well. I went from Physics to BSN myself and had to take statistics and a few others.
