Expatriates provide benefits to multinational corporations (MNCs) when they enact boundary spanning roles. They do so by relaying local information and identifying opportunities that meet internal needs of MNCs. To test hypotheses based on social capital and role theories, we surveyed 232 expatriates. The findings indicated that local experience and the diversity of social networks were conducive to the boundary spanning activities of expatriates, whereas environmental uncertainty and overseas experience had little effect. By engaging in boundary spanning activities, expatriates felt less role ambiguity and gained role benefits, and were more eager to use the resources that were found within different communities of the host country. In addition, those expatriates who engaged in more boundary spanning activities had higher job satisfaction and more power within their own companies than those who did not.
