CIS is the second most quoted immigration research think tank in America.
Pew Research is the number one most quoted, and Pew has like ten times more people than CIS.
CIS was an overtly Right wing institutional leader in stopping the Bush-McCain Amnesty during the 2005-2008 period.
Unfortunately, that was a Pyrrhic victory, CIS made a lot of powerful enemies, and their corporate and foundation funding took a big hit.
By 2010, CIS had moved conspicuously to the political center, and they now focus almost entirely on basic research, with little or no political activism.
I think SPLC labeled CIS as a "Hate Group" in 2017.
It was an absurd charge since most of the CIS staff now support limited Amnesties and moderately lower numbers of work visas and Green Cards.
Thank you. :)
