AP- Illegal immigrants plan to leave over Arizona law.

Look at that with just over a week and the law is already working.

Arizona's sweeping immigration bill allows police to arrest illegal immigrant day laborers seeking work on the street or anyone trying to hire them. It won't take effect until summer but it is already having an effect on the state's underground economy.

"Nobody wants to pick us up," Julio Loyola Diaz says in Spanish as he and dozens of other men wait under the shade of palo verde trees and lean against a low brick wall outside the east Phoenix home improvement store.

Many day laborers like Diaz say they will leave Arizona because of the law, which also makes it a crime to be in the U.S. illegally and directs police to question people about their immigration status if there is reason to suspect they are illegal immigrants.

....An estimated 100,000 illegal immigrants have left Arizona in the past two years as it cracked down on illegal immigration and its economy was especially hard hit by the Great Recession. A Department of Homeland Security report on illegal immigrants estimates Arizona's illegal immigrant population peaked in 2008 at 560,000, and a year later dipped to 460,000.

The law's supporters hope the departure of illegal immigrants will help dismantle part of the underground economy here and create jobs for thousands of legal residents in a state with a 9.6 percent unemployment rate.

Kavanagh says day labor is generally off the books, and that deprives the state of much-needed tax dollars. "We'll never eliminate it, just like laws against street prostitution," he says. "But we can greatly reduce the prevalence."
