National identity significantly influences immigration policy as governments often shape laws based on cultural perceptions and values associated with a nation. Decisions about who is allowed to enter or remain in a country reflect larger questions about belonging, assimilation, and social cohesion. For example, nations with a strong sense of ethnic identity may adopt stricter immigration policies to preserve cultural homogeneity, while those embracing multiculturalism may implement more inclusive practices. National identity consequently serves as a lens through which policymakers interpret immigration challenges and opportunities.
