People who have TPS (temporary protected status) or even their green card (legal permanent residence) are still at risk of deportation. For example, someone may lose their TPS if they have been convicted of certain crimes. After one of my clients was convicted of his 2nd driving while intoxicated offense, he lost his TPS, was placed in removal proceedings and then hired me. We are applying for Cancellation of Removal now. The GPS monitoring device will eventually be removed with time and after showing that you are compliant (with appointments, etc). Good luck.
