The United States is a nation of nations, expanded by immigration since the first Spanish settlements in what is now Florida in the 1500's. In 2013, the U.S. Census Bureau reported that 40 million legal and undocumented immigrants comprise 13% of the total U.S. population. Large numbers of immigrants impact employment, the economy, schools and social services. While all 23 campuses of the California State University system have declared themselves "sanctuaries," concern for potential threats to national security, decline in wages, loss of employment and economic opportunities have given rise to anti-immigrant sentiment in many communities.

An illegal alien is not a permanent resident alien, but would be an immigrant under the INA's definition.
