just like texasketa said, ask her to join a community college and have her finish her pre req. Ask her to atleast maintain 3.5 CGPA, getting into nursing school can be tuff. I don't think you can just start a nursing school, you need to get into the program. 

Also if she is just coming to usa, she needs to live in the state for minimum 12 months to establish a domicile and receive in-state tuition. Suggest her to work atleast 20 hours a week on campus so that she doesn't end up being in a pile of debt. 

first year of school should be breeze , so working up and paying for the school shouldn't be tuff..goodluck
