I see. No, her current status depends on me. I'm on F1, and now she's on F2 & B2. She never violated her status within the US, which was confirmed by the officer yesterday. The officer said her status was valid all the time. The only issue was the officer kept asking her if she had been denied a visa to the US. She said no, and the officer assumed that my wife didn't really remember the denial. She also answered 'no' on the i485 form. Still, the truth is her visa got denied several times, like 9 years ago, but she eventually got a student visa to the US. Maybe this part caused the officer's attention and need to review the case much longer. Let's see what will happen in the next few days or months.
