Arizona Gov. Jan Brewer is nearing a deadline to act on the nation's toughest state legislation against illegal immigration.
A Saturday deadline was set when the legislation landed on her desk Monday. She can sign, veto or allow the bill to become law without her signature.
The sweeping measure gives police new duties to question people about their immigration status in some circumstances, targets hiring of illegal immigrants and creates a state crime for them to not have papers to be in the country illegally.
Arizona has an estimated 460,000 illegal immigrants and is the nation's busiest border crossing point.
