Don't bother the academic advisor. Maybe the dept. head, to give them a heads up, but this really isn't within their purview. The university's ombudsman might be helpful.
I gotta tell you, this guy probably has the same attitude in his studies, because he's arrogant. As in, he probably has similar justifications for plagiarism and cheating, when caught.
And this could be his weakness. Because there is a move by the current administration to be more strict about enforcing requirements for student visas.
