Immigration policy refers to the laws, rules and practices that govern a country's immigration system. It outlines the procedures for people to enter and remain in a country as permanent residents or citizens. Immigration policies vary from one nation to another depending on factors such as economic needs, political climate, cultural values, historical context, and international agreements. The policy may include criteria for granting visas, work permits, refugee status, and naturalization procedures among other things. It also addresses issues related to border control, deportation, and the treatment of immigrants within a society. Overall, an immigration policy reflects a government's approach towards managing migration flows and integrating newcomers into its social, economic, and political fabric.
