Irregular migration refers to the movement of people who cross borders without the necessary legal permissions or documentation. This can include individuals who enter a country without a visa or those who overstay their authorized period. Irregular migrants often seek better economic opportunities, safety from conflict, or family reunification. Countries may face challenges in managing irregular migration, as it can lead to issues related to security, public services, and social integration. Governments often implement policies to address these challenges, balancing the need for border control with humanitarian considerations for migrants, including those fleeing persecution or violence in their home countries.
