F1 student status after expel from university?

Your visa's validity ended as of the day you were expelled. You have already overstayed. Leave immediately. You cannot remain in the US while you try to apply for admission to another university. And persons who have been expelled from a school are typically inadmissible elsewhere. You have no choice but to return to your country of citizenship immediately. You are already subject to arrest, detention, deportation, etc, since you were expelled from school. Go home and hurry up about it! 30 days from date of expulsion from school you start racking up time for bar to reentry.
