In comments during a formal welcoming ceremony on the White House east lawn Wednesday, President Obama talked about the many bonds between Mexico and the U.S., including the bond of family. He said Mexican families have lived in the United States for generations. In his remarks, President Calderon took the opportunity to criticize a new immigration law in the U.S. border state of Arizona, saying the new measure will force many Mexican families in the U.S. to "live in the shadows," and face discrimination. Following the ceremony, the two leaders, along with Secretary of State Hillary Clinton, are scheduled to enter into bilateral talks, where immigration is expected to be a key issue. President Obama has called the new Arizona law "misguided," saying it threatens to undermine basic notions of fairness that Americans cherish. The Calderon government has issued a travel warning for Arizona. The Obamas will host the Calderons at a state dinner Wednesday evening. The dinner is only the second such event so far during Mr. Obama's presidency. The two presidents have met several times at international meetings and the Mexican First Lady hosted Mrs. Obama in Mexico last month. The Arizona law takes effect in a few weeks. It requires immigrants in Arizona to carry registration documents with them at all times and for police to question people if there is reason to believe they are illegal immigrants.  Opponents say the law will result in racial profiling, but supporters say the measure will help combat crime blamed on illegal immigrants. President Obama says he wants the U.S. Congress to make progress this year on comprehensive immigration reform.  The U.S. and Mexican leaders also are expected to discuss the drug war in Mexico, which has affected both sides of the border. At least 23,000 people have died in drug-related violence since Mr. Calderon took office in 2006. The Mexican leader is due to address the U.S. Congress on Thursday. Some information for this report was provided by AFP, AP and Reuters. .
