You mentioned she is doing a Bar exam?????
I was watching a lady on Hacking yesterday, she had screwed things up, I had sympathy she did not come across as being very bright, not sure I am now allowed to say that, but we have the Internet, you are looking at discretionary relief, let is be real here. Fortunately her case is easily fixable.
Obviously my knowledge of your case is limited, my guess is that the I 601a is going to be the way to go.
