Glyndwr University has lost its ‘highly trusted’ sponsor status after the test scores of more than 230 students it sponsored were identified as being invalid, while the University of West London (UWL) and the University of Bedfordshire have been barred from sponsoring new international students pending further investigations to decide whether they will also be suspended.
Nearly 300 overseas students at the private London School of Business and Finance (LSBF) worked and paid tax last year, with one student working 60 hours a week for six months.
In an investigation, HMRC found that some of the students were earning £ 20 000 per year despite rules preventing them from working 20 hours per week during term time.
