MEXICO CITY -- A delegation of Mexican senators plans to go to Arizona to listen to opinions about the U.S. state's immigration law, but it will not take part in any protests against the controversial measure.

The Mexican Senate has already voiced its opposition to the Arizona law, which will make it a state crime to be in Arizona without documents. Mexico's government says the law is discriminatory and raises the risk of racial profiling.

Sen. Luis Alberto Villarreal says "we are not going to demonstrate," adding that the senators have respect for a nation's laws.

Sen. Claudia Corichi said Monday the delegation will meet with Mexican consuls to plan what actions to take if the law goes into effect July 29.
