How to control the movement of people across borders has become an increasingly important political issue. This chapter inquires into the means by which migrant-sending and migrant-receiving states can maintain harmonious relations and avoid the conflict often resulting from differing national policies. It looks at various kinds of policy discord, freedom of movement as a human right, differing exit and entry regulations, and regimes for migrant laborers, as well as the phenomenon of the “brain drain” from one nation to another. Among specific cases analyzed are political exile involving North and South Korea, the issue of Jewish emigration, Cuba’s population dumping policy, the refugee crisis from the Third Indo-Pakistani War of 1971, and the Bracero program, a US-Mexican attempt at migration control.
