I sympathise with the nursing students. They may well have been genuine, and wanted to obtain a degree which will be a requirement for registration as a nurse with the UK Nursing and Midwifery Council from 2013. Of course they should have known that it's illegal to work - as opposed to studying - more than 20 hours a week. But surely it was the University's responsibility - and enlightened self-interest - to monitor their activity and warn them of the consequences of flaunting immigration rules.
