Return of Korean(Goryeo people) with a history of migration have changed their identity over time. Rather than forcing national identity on them living in the era of globalization, identity research is needed for more meaningful and advanced policies through research on their identity. The national identity of Return of Korean(Goryeo people) shows that attributable factors, responses to minority policies within the residential area, and influences on transnational boundaries can be important factors that shape their identity. However, as Yoon In-jin pointed out, if Return of Korean(Goryeo people) lose their native language, their national identity will inevitably remain quite symbolic and spiritual, and therefore, it is likely to be superficial and ideological. In the end, the series of identities currently shown by the Return of Korean(Goryeo people) can be seen as extremely abstract and variable forms of identity lacking objective vitality.
