Do state work eligibility verification laws reduce unauthorized immigration?

During the 2000s, several states adopted laws requiring employers to verify new employees' eligibility to work legally in the USA. This study uses data from the 2005-2014 American Community Survey to examine how such laws affect unauthorized immigrants' locational choices. The results indicate that having an E-Verify law reduces the number of less-educated prime-age immigrants from Mexico and Central America-immigrants who are likely to be unauthorized-living in a state. We find evidence that some new migrants are diverted to other states, but also suggestive evidence that some alreadypresent migrants leave the country entirely.
