The only grounds for removal from a school or anything else under US immigration law is the mere fact that you're in our country in violation of US immigration law which has nothing whatsoever to do with any civil right, any equal protection clause, the 14th amendment of Plyler vs Doe which just says if you let them stay, you can't charge them tuition to attend a school that no one else is being charged. It was a silly decision, but it doesn't have any impact or effect on the federal government's authority to enforce US immigration law any time, anywhere.
