ABSTRACT
The concept of citizenship is fundamental to the question of rights of residence and freedom of movement of the individual. An individual’s right to enter and remain in a country depends upon his or her status. Under international law no state may deny entry to its own nationals where they are not entitled to enter or remain in other states. However, subject to international obligations, states may by law determine which non-nationals may enter and remain within their territory, and may remove those who enter and remain unlawfully. In recent decades the increasing number of refugees and other migrants have required new laws to regulate entry and entitlement to remain. In this chapter a broad overview of the law is given.
