How can I get an illegal immigrant deported. I have already called the INS and gave them all her information. What more can I do?

Is there a specific reason why you would like her deported?
Is she involved in illegal activities?

I wouldn't make much effort, she will be back in another year or two.
Did you know they had illegals building our division wall between Mexico and the USA?
That ended real quick, after that info was leaked. ;)

You gave the INS the information, then let it go. Unless you actually see this person committing a crime, which you can report to the police. Somehow, in the crazy place we live in, the illegal immigrants can access attorneys, which cost them nothing (courtesy of our tax dollars), and sue the person who they claim is harassing them.
