CIS meaning in Community ?

The Center for Immigration Studies (CIS) is an anti-immigration think tank. It favors far lower immigration numbers, and produces analyses to further those views. The CIS was founded by historian Otis L. Graham and eugenicist and white nationalist John Tanton. The organization was founded in 1985 as a spin-off from the Federation for American Immigration Reform, and is one of a number of anti-immigration organizations founded by Tanton, along with FAIR and NumbersUSA.

Reports published by CIS have been disputed by scholars on immigration, fact-checkers and news outlets, and immigration-research organizations. The organization had significant influence within the Trump administration, which cited the group's work to defend its immigration policies. The Southern Poverty Law Center designated CIS as a hate group with ties to the American nativist movement. CIS's lawsuit against the SPLC over the designation was dismissed.
