Immigration law includes the national statutes, regulations, and legal precedents governing immigration into and deportation from a country. Strictly speaking, it is distinct from other matters such as naturalization and citizenship, although they are sometimes conflated. Countries frequently maintain laws that regulate both the rights of entry and exit as well as internal rights, such as the duration of stay, freedom of movement, and the right to participate in commerce or government.Immigration law includes the national statutes, regulations, and legal precedents governing immigration into and deportation from a country.
