Some of these problems must be solved preemptively or simultaneously. Accordingly, this paper tried to present basic policy measures to raise and solve these problems at a macroscopic level; why, who, and how much will be brought in (immigrant influx) the migrants concerning the demographic structure of Korea, how to manage, utilize, and socially integrate the immigrants (social integration), and how to effectively achieve immigration governance (Immigration administration) from the point of view.
