Despite recent trends indicating an increased use of host-country nationals in foreign operations, more and more international firms are finding it necessary to send parent-country nationals as expatriates to live and work abroad. Among the reasons for this increase are: the rapid expansion of international business; the necessity of maintaining organizational control and coordination; and a need to develop a cadre of managers with international expertise. Currently, for example, 80 percent of midsize and large companies send professionals abroad, and 45 percent plan to increase the number they have on assignment (Black and Gregersen, 1999).
