So the RP does not get renewed??? ..... then you will soon have an expired RP....

Do you get be treated here or are you sent home the next day?

Will you get a temporary stay visa until you get treated and pass the medical test?

Will the companies carry the burden of the medical costs since you contracted the disease here while your RP was valid?

It is good to have an annual medical checkup (our company has) since we are not getting younger but this should not be a reason to terminate your employment or cancel your visa outright if the disease is curable.
