Abstract

This paper reviews selected theories of international migration including social network and human capital. It discusses the nature of social networks among immigrants and the costs and benefits for the sending and receiving countries. The history of social network theory in social work practice is revisited. Given the current importance of immigration in the Southwest, the strength and limitations of applying networking principles in practice with immigrants in the border areas are included. This article does not focus on the complexity of networks among refugees or asylum seekers, where government population dispersion or resettlement policies might change their circumstances.
