Hi there,
Coventry University Student Ambassador here,
It is recommended that your friend should initially book a meeting with the ISC (International Student Compliance) team if they have received an email regarding it. Moreover, I would also suggest seeking the university's support for health and well-being if necessary, as it could be helpful in supporting the case.
I hope that would be helpful towards sorting this out,
Thank you,
Kind Regards,
Harleen.
