One of the objectives of trade liberalization under the WTO setting is to expand global trade and make it an avenue for economic growth in all trading countries. The General Agreement on Trade and Services (GATS) has laid down the general framework that would govern the promotion of global trade in services. A key mode of supply of services is the movement of workers and professionals from one territory to another to supply various forms of services. In turn, this avenue for enhancing global trade in services may be facilitated or obstructed by the degree and levels of obstacles among countries in accepting the competence of these foreigners to perform the service.
