The issue of crimes committed by illegal immigrants to the United States is a topic that is often asserted and debated in politics and the media when discussing Immigration policy in the United States. There is scholarly consensus that illegal immigrants commit less crime than natives. Sanctuary cities—which adopt policies designed to avoid prosecuting people solely for being in the country illegally—have no statistically meaningful impact on crime, and may reduce the crime rate. Research suggests that immigration enforcement has no impact on crime rates.
