Migration policy affects national identity by shaping societal perceptions of who belongs. It can influence cultural integration, social cohesion, and economic contributions, thereby altering the fabric of a nation. Policies that embrace inclusivity may foster a more diverse national identity, while restrictive measures can create divisions and prompt backlash. Migration policies also reflect broader political ideologies, with implications for international relations. Ultimately, the way a country manages migration can define its self-image and values, impacting how its citizens view their own national identity.
