It depends on (1) when and where she entered the US, (2) her exact manner of entry, (3) any immigration flings prior to April 30, 2001, and (4) any arrests, charges or convictions. She may not be eligible to get her green card in the US. If she needs to apply for the immigrant visa at her home consulate, she will need a waiver, which will likely require an extreme hardship to a US citizen spouse or parent. Get this information about her background and consult with an experienced immigration attorney.
