Immigration law is a branch of law that deals with the regulations and policies governing the entry, stay, and rights of foreign nationals in a particular country. It addresses issues such as visa requirements, deportation, citizenship, asylum, and refugee status. Immigration laws are typically complex and vary from country to country, with many restrictions and requirements in place to regulate the movement of people across borders. This area of law is constantly evolving due to changing political, social, and economic landscapes, as well as international issues such as migration flows and the global refugee crisis.
