Center for Immigration Studies - numbers of illegal undocumented immigrants - and legal immigrants
The Center for Immigration Studies is the nation's only research organization focusing solely on U.S. immigration policy and the consequences of documented and undocumented immigration into the United States.
Here we present selected CIS documented and undocumented immigrant studies analyzing the numbers of legal immigrants and illegal aliens present in the United States.
CIS differs from many immigration research institutions since most non-partisan centers researching undocumented immigration - like the Pew Hispanic Center and the Migration Policy Institute - are generally in favor of higher levels of immigration. Other research institutions like the liberal Center for American Progress and the libertarian Cato Institute and are also ideologically in favor of high immigration and legalizing undocumented immigrants.
The Center for Immigration Studies - CIS - was founded in 1985 and is an independent, non-partisan, non-profit, research organization. The Center for Immigration Studies provides reliable and accurate information to news media, concerned citizens, policymakers, and the academic community concerning the economic, fiscal, security, social, and environmental consequences of legal and undocumented immigration into the United States.
The diverse board of directors for the Center for Immigration Studies includes former government officials, active and retired university professors, and civil rights leaders.
