7/13/15 Report from American Immigration Council – For more than a century, innumerable studies have confirmed that immigrants are less likely to commit serious crimes than the native-born, and high rates of immigration are associated with lower rates of violent crime and property crime. This holds true for both legal immigrants and the unauthorized, regardless of their country of origin or level of education. In other words, the overwhelming majority of immigrants are not criminals by any commonly accepted definition of the term. For this reason, harsh immigration policies are not effective in fighting crime.
