WTO GATS Mode 4
Under the General Agreement on Trade in Services (GATS), the movement of natural persons is one of the four ways through which services can be supplied internationally. Otherwise known as “Mode 4”, it covers natural persons who are either service suppliers (such as independent professionals) or who work for a service supplier and who are present in another WTO member to supply a service. It is a multilateral framework available on a non-discriminatory basis to all WTO Member States.
