About one quarter of foreign born persons in the U.S. are unauthorized to be here. 45% of Americans say that most immigrants living in the U.S. are here legally; 35% say most immigrants are in the country illegally, while 6% volunteer that about half are here legally and half illegally and 13% say they don’t know.
26% of college grads think that most are here illegally. So do 27% of liberals think. 51% of Republican-leaning non-college grads think so.
