Do I need to report sponsored staff as absent via SMS?
The UKVI will not take enforcement action against sponsors who continue to sponsor students or employees despite absences due to coronavirus. You do not need to report employee absences related to coronavirus. This can include absences due to illness, their need to isolate or inability to travel due to travel restrictions. You do not need to withdraw sponsorship if because of coronavirus where an employee is absent from work without pay for more than 4 weeks.
The Home Office will keep this under review.
