In 2015, then-department head Dennis Judd changed an undergraduate student's grades without consultation with Choi, the suit says. When Choi asked Judd about it, the lawsuit alleges that Judd said Choi, "as a foreigner, has to keep in mind who he is dealing with and what he is wishing for," and that Judd "knows that many Koreans are stubborn and do not understand American culture of compromise when dealing with their boss."
