Illegal immigration is the migration of people across national borders in a way that violates the immigration laws of the destination country.
Immigration is the international movement of people into a destination country of which they are not natives or where they do not possess citizenship in order to settle or reside there, especially as permanent residents or naturalized citizens, or to take-up employment as a migrant worker or temporarily as a foreign worker.
Borders are geographic boundaries of political entities or legal jurisdictions, such as governments, sovereign states, federated states, and other subnational entities.
Immigration law refers to national government policies controlling the immigration and deportation of people, and other matters such as citizenship.
