Calderon condemned the Arizona bill but also indicated [remarks] that both countries must work together in order to develop a comprehensive approach to immigration that will benefit the entire region. Obama's stance on the Arizona law reflects his administration's immigration policy [official website] that aims "to bring people out of the shadows."

The Arizona bill, signed into law [JURIST report] in April by Governor Jan Brewer, has caused intense controversy.

That lawsuit joined two others filed last month [JURIST report] questioning the constitutionality of the law.
