a high commissioner heads a high commission, just as an ambassador heads an embassy. High commissioners are therefore also of ambassadorial rank. The term high commission is used to refer to the diplomatic mission of one former British colony - or the United Kingdom - in another (i.e. diplomatic missions within the Commonwealth of Nations).

In view of Singapore's small population and limited resources, it is not tenable for Singapore to have resident missions in all countries with which it has diplomatic relations. Instead, Singapore appoints non-resident ambassadors (NRAs) or non-resident high commissioners (NRHCs) to certain countries. NRAs/NRHCs are resident in Singapore, but make regular representational visits to their country of accreditation. They are typically non-diplomats, though some are former diplomats. When on representational visits or while performing other official duties, NRAs/NRHCs have the same powers and authority as resident heads of mission.
