The long-awaited revision of rules for work permits, entry permits, etc, has been unleashed by the Department of Immigration. Anyone on an Entry Permit is required to change to Residence Permit … at a cost, I am told, of K4million (US$800). People on Work Permits will be required to change to new permits at the expiration of their existing one.
