One of the consequences of globalization is the rise of intermarriage. It is often assumed that intermarriage for ethnic minorities is the ultimate litmus test of integration. But intermarriage is sometimes regarded as the final stage of assimilation among immigrant racial and ethnic minorities especially in the second stage of their life-their children. Assimilation refers to the myriad social processes that bring ethnic minorities into the mainstream of economic, political, and family life of Korean Society.
