On one hand, she shouldn't be in the country; she knowingly violated the immigration rules and should be deported as a consequence. On the other hand, I know plenty of immigration-violators who are released on their own recognizance and I fail to see what is gained by her detention pending deportation. Tough situation, I agree. But there's a point to be made here.
Just because "She exemplifies the kind of person we want as a U.S. citizen," doesn't mean she can flout the law. I know a doctor from Canada who plays visa games. She's a good person otherwise. But she once lied to the US Customs Inspector at the border and was turned away when caught in the lie. She was angry at him. As if the fact that she wants to be here,by itself, entitles her to get in. We have immigration rules. Follow the damn things and you can get here, especially if you're a professional. But if you break them, you're just another criminal.
