We've all heard a lot about Arizona's controversial and stringent immigration law, SB 1070, which allows Arizona police to question anyone they suspect may be in the country illegally. But 44 other states have introduced immigration legislation of their own since the beginning of 2010. Some worry that the U.S. may soon be facing a patchwork of different laws for different states.
Yale law professor Peter Schuck says that states are trying to make their own laws because federal efforts aren't moving quickly enough. He also says that while the fiscal burden of illegal immigration falls on states, the benefits of immigrant communities — like increased tax revenue and economic expansion — mostly go to the federal government. Schuck is the author of several books on immigration including "Understanding America: the Anatomy of an Exceptional Nation."
