NEW YORK – Hundreds of thousands of people demanding U.S. citizenship for illegal immigrants took to the streets in dozens of cities from New York to San Diego on Monday in some of the most widespread demonstrations since the mass protests began around the country two weeks ago.

Rallies took place in communities of all sizes, from a gathering of at least 50,000 people in Atlanta to one involving 3,000 people in the farming town of Garden City, Kan., which has fewer than 30,000 residents.

Demonstrators in New York City held signs with slogans such as “We Are America,” “Immigrant Values are Family Values,” and “Legalize Don’t Criminalize.” One sign said: “Bush Step Down.”

“We love this country. This country gives to us everything,” said Florentino Cruz, 32, an illegal worker from Mexico who has been in the United States since 1992. “This country was made by immigrants.”

The protesters have been urging lawmakers to help an estimated 11 million illegal immigrants settle legally in the United States. A bill passed by the House would crack down on illegal immigrants and strengthen the nation’s border with Mexico. A broader overhaul of immigration law stalled in the Senate last week.

Monday’s demonstrations followed a weekend of rallies in 10 states that drew up to 500,000 people in Dallas and tens of thousands elsewhere. Dozens of other rallies, many organized by Spanish-language radio DJs, have been held nationwide during the past two weeks, including one with more than 500,000 people in Los Angeles.

In North Carolina and Dallas, immigrant groups called for an economic boycott to show their financial impact. In Pittsburgh and other cities, protesters gathered outside lawmakers’ offices. At the Mississippi Capitol, they sang “We Shall Overcome” in Spanish.

In Atlanta, many in white T-shirts, waving American flags, joined a two-mile march from a largely immigrant neighborhood.

The Rev. James Orange from the Georgia Coalition for the People’s Agenda compared the march to civil rights demonstrations led by the Rev. Martin Luther King Jr. and farm-labor organizer Cesar Chavez.

“People of the world, we have come to say this is our moment,” Orange said.

In New Jersey – with the Statute of Liberty in the background – several hundred people listened to speeches and waved U.S., Colombian and Mexican flags.

Several hundred people gathered in New York’s Washington Square Park before marching to City Hall. Many waved flags, both American and of countries of their origin. Korean-Americans beat drums nearby.

One of the Korean drummers, Grace Nam, 35, who is an American citizen, said: “We just need to make our voices heard. You want to live in a place where people are treated with dignity.”

Peter Lanteri, director of New York’s chapter of the Minutemen, a volunteer border watch group, said he thought it was “ridiculous” that illegal immigrants were protesting for their rights.

“Illegal is illegal, and they break our laws to come here,” Lanteri said by telephone. “We want the illegal immigration stopped and the borders secured.”

Supporters in San Diego planned to hold a ceremony to honor immigrants who died while illegally crossing the border.

In Phoenix, police estimated that 25,000 people gathered for a rally.
