The new U.S. administration wants to overhaul America’s migration system, cracking down on undocumented migrants. In total there are an estimated 11.1 million unauthorized migrants in the U.S. of which some 6.75 million took refuge in the big metropolitan areas, according to data collected by the Pew Research Center. Some of these metro areas have so-called sanctuary cities at their center. Theses do not use municipal funds or resources to enforce national immigration laws.
Cities profit from immigration a great deal, which led some mayors to openly take a stance against the new migration policies.
