The current migration patterns in East Asia result from changes which include global capitalism changes and technological advancements, native ethnic groups and migrant populations, and established regional migration patterns. This chapter needs to analyze the impact of cultural identities on East Asian migrant experiences while identifying the national factors that either support successful integration or lead to integration failures. Moreover, it examines different East Asian countries to show how cultural identities of immigrants affect their ability to integrate into society through social, economic, and political methods. Furthermore, the research investigates elements which affect social integration throughout East Asian nations. Some of these factors are common across countries while others exist because of particular national circumstances. This approach enables the results to produce specific policy recommendations for improving integration and social cohesion throughout the region. Additionally, it points out the complex regional dynamics which involve identity–cultural elements and migration-related political activities. Finally, the research study shows that organizations need to establish complete systems which build relationships between people and allow different cultures to share their traditions to create successful environments for local residents and migrants.
