The Center for Immigration Studies is an independent, non-partisan, non-profit research organization founded in 1985. It is the nation's only think tank devoted exclusively to research and policy analysis of the economic, social, demographic, fiscal, and other impacts of immigration on the United States.

It is the Center's mission to expand the base of public knowledge and understanding of the need for an immigration policy that gives first concern to the broad national interest. The Center is animated by a pro-immigrant, low-immigration vision which seeks fewer immigrants but a warmer welcome for those admitted

The Immigration Advocates Network is a free national online network that supports legal advocates working on behalf of immigrants' rights.
