Oxtail01, more illegal immigrants live in Southern California than anywhere else in the U.S. About 1.4 million illegals live between southern Ventura County border near Los Angeles and the U.S.-Mexican border. It is the largest cluster of illegals in the country. But don’t take it from me; take it from the Orange County Register. http://www.ocregister.com/2017/02/10/more-undocumented-immigrants-live-in-southern-california-than-anywhere-else-in-us/
