Politicians in the US state of Florida are the latest to craft a bill modelled on a controversial law in Arizona, local media reports said.
The law, signed in April, gives broad powers to police to question people they suspect of being in the country illegally.
Critics say it encourages racial profiling. Now politicians in at least six states have introduced bills similar to Arizona's.
"This is shameful, copy-cat legislation particularly in states that are experiencing the highest number of foreclosures in the country, the highest unemployment rates and the highest deficit of their state budgets," Nativo Lopez, who works at the Mexican-American Political Association, told Al Jazeera.
"It's shameful because they could theoretically deport all the estimated number of undocumented individuals in their states and that still would not resolve their deficits or bad unemployment.
