This study focused on the reality that it is difficult for Korean-Chinese youths who migrated to South Korea in their teenage years to be integrated into the center of society in both South Korea and China. The purpose of this study is to give alternative thoughts to reduce the transnational precarity of life through the analysis of the education and work experience of migrant youths who experienced school dropout during the migration process. As a result of the study, the out-of-school migrant youths were connected to both South Korea and China, but at the same time, were in a paradoxical situation of being located on the social margins in both South Korea and China. It was difficult for them to move from the position of migrant workers as their relationships with family, education, labor, and the state were generally precarious. Therefore, in order for migrant youths to move to a more stable social position rather than remain as a youth precariat group in both South Korea and China, it is necessary to change policies and social perceptions regarding migrant youth. First, it is necessary to change the policy for migrant youth in such a way that the right to education and the right to choose a job can be guaranteed in more diverse ways. Therefore, the policy goal needs to be readjusted in terms of Securing the possibility of entry into South Korea s mainstream society and social mobility of immigrant youths . Second, it is necessary to change the perspective on migrant youths who spend their adolescence in South Korea and are transitioning to adult. The future they aspire to as a young people were not the lives as migrant workers. In the future, the social integration policy needs to be readjusted in such a way that migrant youth can enter South Korea’s mainstream society.
