Phoenix, Arizona (CNN) -- Arizona Gov. Jan Brewer signed a bill Friday that requires police in her state to determine whether a person is in the United States legally, which critics say will foster racial profiling but supporters say will crack down on illegal immigration.
The bill requires immigrants to carry their alien registration documents at all times and requires police to question people if there is reason to suspect that they're in the United States illegally. It also targets those who hire illegal immigrant day laborers or knowingly transport them.
