(CNN) - Now that Arizona lawmakers have passed what's considered some of the toughest immigration legislation in the country, other states are watching to see whether they should follow in the state's footsteps or stand back.
Arizona's bill orders immigrants to carry their alien registration documents at all times and requires police to question people if there's reason to suspect they're in the United States illegally. It also targets those who hire illegal immigrant day laborers or knowingly transport them.
Critics, including immigrant advocates and the American Civil Liberties Union of Arizona, are concerned that the legislation will foster racial profiling, arguing that most police officers don't have enough training to look past race while investigating a person's legal status.
The bill made it through the state Senate on Monday after it was passed by the state House last week. It's now awaiting the signature of Republican Gov. Jan Brewer. Supporters of the measure expect her to sign it. Latino members of Congress are calling on Brewer to veto it.
