Washington ( CNN ) -- A Latino rights group and other immigrant and labor organizations called Thursday for a national boycott of Arizona over the state 's new immigration law , which allows police to ask anyone for proof of legal U.S. residency . The call for a boycott was led by the National Council of La Raza , which bills itself as the largest national Hispanic civil rights and advocacy organization in the United States . Other organizations calling for the boycott include the Asian American Justice Center , the Center for Community Change , the League of United Latin American Citizens , the National Puerto Rican Coalition , the Service Employees International Union , the Leadership Conference on Civil and Human Rights , and the United Food and Commercial Workers union . The groups pledged not to hold major conventions , conferences or other special events involving significant travel to Arizona from out of state and `` asked others to consider whether their purchases of goods and services might perpetuate the unjust and discriminatory law in Arizona , '' La Raza said on its website . `` When a law so contrary to our values is passed , we must act decisively , '' said La Raza President and CEO Janet Murguia . `` We are calling for a boycott because this law will blow open the door to increased racial profiling , wrongful arrests and other discrimination . '' Arizona Gov . Jan Brewer , who signed the immigration measure April 23 , says it does not involve racial profiling or any other illegal acts . The law , known as SB 1070 , is scheduled to go into effect this summer . The measure has drawn criticism in the United States and abroad . In Arizona , the Tucson and Flagstaff city councils voted this week to file suit against the measure . The city councils said they 're taking action because of concerns over enforcement costs and negative effects on Arizona 's tourism industry . In Tucson , council member Regina Romero introduced a motion for `` the city attorney to bring a legal challenge '' because the immigration bill is `` unconstitutional '' and `` a bad law , which could cost the city millions of dollars in lawsuits . '' `` This bill opens the door to racial profiling , and it puts Latinos in Arizona in automatic suspect mode , '' Romero said . Tucson Mayor Bob Walkup said up to 38 percent of retail sales in the city come from legal Mexican visitors . The state immigration law threatens Tucson 's businesses , Walkup said , just when `` the city is just beginning to recover from the economic downturn . '' Criticism also has come from abroad , with the Mexican government issuing an advisory to its citizens last week to avoid travel to Arizona . The Organization of American States expressed its concern about the law last week , and presidents of South American countries meeting in Argentina for a gathering of the Union of South American Nations condemned the law Tuesday . Well-known Mexican writer Carlos Fuentes recommended this week that dark-skinned people , men with mustaches , women who use shawls , or anyone who does not speak English well should not go to Arizona , because the state has `` officially declared itself racist , '' the government-run Notimex news service reported Wednesday . The Phoenix Suns basketball team also criticized the new law , and wore jerseys marked `` Los Suns '' in Wednesday night 's NBA playoff game against the San Antonio Spurs . `` The frustration with the federal government 's failure to deal with the issue of illegal immigration resulted in passage of a flawed state law , '' Suns managing partner Robert Sarver said in a statement . `` However intended , the result of passing this law is that our basic principles of equal rights and protection under the law are being called into question , and Arizona 's already struggling economy will suffer even further setbacks at a time when the state can ill-afford them . '' Arizona legislators say they passed the law because the federal government has failed to safeguard the border with Mexico , allowing more than 450,000 undocumented immigrants to settle in the state . On Thursday , Democratic Sen. Charles Schumer of New York wrote a letter to Brewer , asking Arizona to delay implementing the law for one year `` in order to permit Congress sufficient time to enact comprehensive immigration reform to address Arizona 's security needs .

Groups pledge not to hold conventions in Arizona because of new immigration law . Law allows police to ask anyone for proof of being in U.S. legally . Opponents say it will lead to racial profiling ; supporters disagree . Score: 6
