In Phoenix, police said 10,000 demonstrators marched to the office of Republican Sen. Jon Kyl, co-sponsor of a bill that would give illegal immigrants up to five years to leave the country. The turnout clogged a major thoroughfare.
"They're here for the American Dream," said Malissa Greer, 29, who joined a crowd estimated by police to be at least 10,000 strong. "God created all of us. He's not a God of the United States. He's a God of the world."
And it's not just Arizona (!):
At least 500 students at Huntington Park High School near Los Angeles walked out of classes in the morning. Hundreds of the students, some carrying Mexican flags, walked down the middle of Los Angeles streets, police cruisers behind them.
The students visited two other area high schools, trying to encourage students to join their protest, but the schools were locked down to keep students from leaving, said Los Angeles district spokeswoman Monica Carazo.
In Georgia, activists said tens of thousands of workers did not show up at their jobs Friday after calls for a work stoppage to protest a bill passed by the Georgia House on Thursday.
That bill, which has yet to gain Senate approval, would deny state services to adults living in the U.S. illegally and impose a 5 percent surcharge on wire transfers from illegal immigrants.
Supporters say the Georgia measure is vital to homeland security and frees up limited state services for people legally entitled to them. Opponents say it unfairly targets workers meeting the demands of some of the state's largest industries.
Teodoro Maus, an organizer of the Georgia protest, estimated as many as 80,000 Hispanics did not show up for work. About 200 converged on the steps of the Georgia Capitol, some wrapped in Mexican flags and holding signs reading: "Don't panic, we're Hispanic" and "We have a dream, too."
Jennifer Garcia worried what would the proposal would do to her family. She said her husband is an illegal Mexican immigrant.
"If they send him back to Mexico, who's going to take care of them and me?" Garcia said of herself and her four children. "This is the United States. We need to come together and be a whole."
On Thursday, thousands of people filled the streets of Milwaukee, Wisconsin, for what was billed as "A Day Without Latinos" to protest efforts in Congress to target undocumented workers. Police estimated more than 10,000 people joined the demonstrations and march to downtown Milwaukee. Organizers put the number at 30,000.
