Abstract With the international age coming, a number of studies have been done regarding the management of expatriates, but little research has focused on the expatriates' decisions to quite their assignment. A comprehensive model is developed to test the cause of the expatriates' turnover tendencies. The model is applied both of the theories from socialization and work-family conflict. Date were obtained with a sample of 171 expatriates in Mainland China from Taiwan's international businesses. Results were indicated that work-family conflict and socialization have the direct effect on intent to leave organization and intent to transfer back prior to the completion of their foreign assignments. Work-family conflict, job similarity, organization support have the direct effect on intent-to-leave the job. Family support has both of the direct and indirect effects on the intent to transfer back prior to the completion of their foreign assignments. Parents' health and the youngest child's age have the indirect effect on the expatriates' intent-to-leave through work-family conflict. Expatriate's position has the indirect effect on the expatriates' intent-to-leave through expatriate's socialization. Implication for international HRM researchers and practitioners are discussed.
