International migration profoundly influences domestic policy by introducing new demographic dynamics, increasing cultural diversity, and impacting labor markets. Policymakers must address the challenges and opportunities presented by migration, such as integrating newcomers into society and responding to public concerns about resources and security. These dynamics often spark debates around immigration reform, social services, and national identity. Furthermore, the presence of immigrant communities can shift political landscapes, as they may advocate for their needs and priorities. Ultimately, international migration compels governments to adapt policies that reflect the evolving nature of their populations.
