Immigration policies are rules and regulations set by a country to manage the entry and stay of foreign individuals. These policies determine who can enter, how long they can stay, and the conditions under which they may work or study. Countries often create these policies to balance economic needs, security concerns, and humanitarian obligations. Different countries have varying immigration policies, which can include visa requirements, asylum processes, and pathways to citizenship. For example, the United States has a complex system that includes family reunification and employment-based visas, while Canada emphasizes skilled workers and refugee resettlement.
