only count on official answer

You can only count on official answer, not this kind of wild posts.
Legal issues go to the legal channel, like school student office, USCIS, lawyer, with enough evidance in writing or recording. So once you are in trouble, you were misled instead of intentional.
Sometimes, INS officer can look VERY carefully about your current and past, anything negative may make you regret and helpless.
Obey the rule, anywhere, always.
