Problems regarding UK immigration have resulted in one university's licence to sponsor foreign students suspended.
Glasgow Caledonian University no longer has permission to sponsor foreign students on a temporary basis.
The UK Border Agency (UKBA) removed the university's right to do so after an agency inspection indicated that 150 Filipino nursing students have been working almost full-time.
The overseas students have been taking a BSC Nursing course, which includes a large proportion of work-based learning.
However, UK immigration rules state that students from outside of the European Union are only allowed to work a maximum of 20 hours a week while they are studying.
Students at Caledonian, conversely, were understood to be working full-time in care homes and had only been attending formal studies for one or two days a month when they were supposed to be at classes for a minimum of 15 hours a week.
Commenting on the situation, Phil Taylor, regional director at the UKBA, said: "I can confirm that Glasgow Caledonian University's Tier 4 licence has been suspended following concerns about abuses of the immigration system.
"Highly trusted sponsors bringing in international students must ensure that they are attending the course for which they are enrolled and that they are complying with the requirements of the immigration rules."
He added that the UK immigration authorities make regular checks on sponsors and will consider suspending their licence if they are found not to be fulfilling their duties.
Glasgow Caledonian now has 28 days to demonstrate that it has addressed the problems or its Tier 4 trusted sponsor licence could be revoked.
