Should I put two universities, 2 years apart, together on a resume, or in reverse chronological order with jobs?

I just listened to the recent graduate cast. My wife studied for 2 years at a University in Peru, then came to the US, worked, and is currently finishing her degree. Here is her schooling/work in reverse order

US University - Jan11-Present

Internship - Aug11-Present

Teller at Bank - Mar10-Jul10

Peru University - Aug05 - Mar09

Should she keep the university experience separate like I have it above, or since its education keep it together? Also, should the internship go above or below her US University?
