I was admitted into MSF at UIUC, But I defer it. I think the program is just one year and you can not improve yourself and find a job in such a short time. Please think about it again if you want to stay in USA for more time.
I've consulted one MM last year admitted by UIUC, she told me last year all of 5 UIUC MBA admitted in Beijing was rejected by Visa!! I really think US embassy hate UIUC MBA!
