There are no particular rules making Monegasque citizens unique or deserving of special attention, they are treated like any other non-visa national. Namely, they can give a series of guest lectures at a university for a period of up to one month without a visa. When the month is finished, the person can still remain as a visitor (i.e., without working) up until their permitted 6 month leave-to-enter expires (or whatever term is assigned by the Immigration Officer who lands them). So in this case and assuming the person recovered before their 6 month leave-to-enter expires, nothing would happen.
But what if a visitor is sick and unable to leave at the end of their visit? The official policy is for the person to complete and post an FLR (O) form (application for further leave to remain, other/outside-the-rules) on the grounds of medical illness or poor health. The fee for this application is nearly £1,000 so great care must be taken when filing the application to assure that it is free from errors. The FLR (O) application should be made prior to the expiry of the person’s leave-to-enter and should always be done if the illness is expected to last more than 7 days beyond the person’s visa’s expiry.
There are cases where the expected overstay is very short, for example 1 or 2 days. There are other cases where circumstantial practicalities prevent an FLR (O) application from being lodged at all. Assuming the person has been hospitalised, when they are able to leave the staff will provide them with an NHS Discharge Letter. This has all of the information needed to exonerate an involuntary overstay. It can be shown to the Immigration Officer on departure (if challenged) or included as evidence in the person’s next visa application.
A solicitor should be consulted before selecting either of these routes.
