Immigration policy refers to the laws and regulations that a country establishes to manage the entry, stay, and exit of foreign nationals. These policies determine who can enter the country, under what conditions, and for how long. They can include various categories such as work visas, student visas, and refugee status, each with specific requirements. Countries often adjust their immigration policies based on economic needs, security concerns, and humanitarian obligations. For example, a nation may increase the number of work visas available to attract skilled labor or implement stricter rules to enhance border security.
