Can I check somehow if person got deportation status on profile?

Friend of mine came to US on J1 visa. It expires in 3 months and she stayed almost 2 years
illegally. Than she went back home to her home country. She got no marks on her passport
for overstaying visa. It was 4 years ago. Now she wants to visit USA as a tourist.
Is she gonna have problems in consulate for tourist visa ? Or maybe problems on the US border?
Thanks for all answers!
