This ethnographic study attempts to understand the transnational life of the factory managers working in Korean owned multinational factories in pan-HCMC (Ho Chi Minh city) area. For the purpose, this study examines three transnational aspects of the Korean factory managers`` lives as follows. First, this study explains why and how the Korean factory managers have immigrated into the city and what is their socialeconomic status in the Korean community there. Second, the Korean managers`` transnational lives in the workplace(s) are explored interms of their working conditions, class consciousness, and nationalor ethnic identity. Lastly, this study interprets the transnational characteristics of their lives in dwelling-living places in association with their social relations as well as the way how they care their own families. The structural reasons why the Korean managers needed andcould live and work in the factories in pan-HCMC is evident. As the global production system has been restructured, Korean laborintensive factories had to move into new areas in search of cheaplabors. In addition, the global labor market of skilled managers were regionalized and differentiated in line with ethnic or nationalidentity; The Korean factories in East Asia still preferred Korean skilled managers to control the native workers. Under the circumstances, the Korean skilled managers should and could move into the new working places such as the factories in pan-HCMC area. The main transnational characteristics that the Korean managersreveal in the transnational workplace(s) are their contradictory class consciousness derived from their own dual and flexible positions. Onone hand, they are only skilled workers whose political economicinterests are not consistent with or against those of capitals. On the other hand, they need to control the native(Vietnamese) female workers and serve for the interests of capitals as foreign malemanagers who have same nationality with capitals. In the context, the Korean managers engage in politics of national or ethnic identity rather than politics of interests and thereby mystify their own classconsciousness. The transnational characteristics of the Korean factory managers`` lives found in their dwelling-living places are also deeply associated with their political economic conditions. They manage to reproducetheir households economically and socially as a working class. Inso doing, they experience complex and contradictory emotions as amale patriarch who need to take care of their own transnational families under the tough political economic conditions. In conclusion, this study predicts that the transnational lives ofthe Korean factory managers working in pan-HCMC area can be aggravated as the future of their factories are uncertain under the incessantly transforming global production regime and their factories`` constant attempts to localize their managements as a response to it.
