Immigration authorities in Australia have cancelled 15,066 foreign student visas in the last one year, and the worst hit are Indians. Of the total, 3,624 students lost their visas because they flunked in some or all subjects or were no-shows to class, the Herald Sun reported. This was a 37 percent rise in visa cancellation.
