Immigration policy refers to the laws and regulations that govern how individuals from other countries can enter, reside, and become citizens in a specific nation. These policies can include visa requirements, asylum procedures, and pathways to citizenship, which vary widely from one country to another. Governments create immigration policies to manage the flow of people across their borders, balancing economic needs, security concerns, and humanitarian obligations. For example, the United States has a complex immigration system that includes family reunification, employment-based visas, and refugee admissions, reflecting its diverse population and historical role as a destination for immigrants.
