An engineering professor at the University of Wisconsin-Milwaukee has pleaded guilty to convincing foreign graduate students from China to pay tuition expenses to his company and pocketing the money, even though they owed no money to study at the school.
But prosecutors said that because the graduate students and professors were working as research assistants at the school, their tuition had been waived. Liu, instead, kept the money and used it to make investments and pay off his credit-card bills.When confronted by investigators about why he did it, Liu allegedly told them: “That’s the difference between China and the U.S.. . . You don’t know the culture of China.
