It's probably not possible under the law, but if I was the judge, I'd offer this lady a choice:
Option 1: go to jail, after which she will be deported.
Option 2: voluntarily deport herself back to her country of origin. If she does this, the prison sentence will be set aside. However, if she re-enters the USA, and is caught, she will go directly to jail to serve the entire sentence.
How's that?
