Center for Immigration Studies

The Center for Immigration Studies is an independent nonprofit think tank that advocates for lower immigration levels and stricter enforcement, placing it firmly on the restrictionist right of the U.S. immigration debate. It is funded primarily by private foundations, with the Colcom Foundation as its dominant financial backer. Under the Trump administration's second term, CIS has been broadly supportive of the administration's immigration agenda, with its executive director publicly praising Trump's enforcement actions as a major improvement over the prior administration.
