The global migration shows that our world are increasingly becoming heterogeneous, multi-racial and multi-cultural. This study argues that lifelong learning should play an active role in the age of global migration. In this regards, this study analysed conceptual relations between migration and lifelong education. It also demonstrated how lifelong equation policy and its provision engaged with immigrants who have crossed borders as new learning agency in Korean society. Major findings showed that although a few researches and discourses have addressed the issues of global migration and immigrants in the field of lifelong education, still there are many restrictions and limitation. First, a vision and perspective of lifelong education has not integrated into lifelong education policy and its individual provision. Second, owing to the dilemma of multiculturality and multiculturalism in Korea, the targets and participants of lifelong education provision are too limited, focusing on the group of female marriage immigrants. Third, the contents of education provision are not comprehensive. Despite diverse efforts in policy level, its discourse anchors on mainly assimilation model, by providing duplicated education programmes of korean language skills and cultural understanding to marriage migrants. Forth, lack of vision and principle of social inclusion including immigrants hindered social engagements and participation between different agencies in Korean society. This study criticized current lifelong education provisions should be re-constructed engaging with migration and multicultural social configuration in Korea. Furthermore, it can be argued that many researchers and practitioners should pay a keen attention with migration and new learning trajectory of immigrants. Given long lasting epistemology of lifelong education, it can lead a certain level of reform of lifelong education law and relevant policy empowering different learning agencies of race, ethnicity, nationality and class in the host society.
