Illegal immigration into the United States has sparked heated debate in Congress roiled the two main political parties and prompted hundreds of thousands of immigrant supporters to take to the streets recently in peaceful demonstrations nationwide. At stake are the lives and livelihoods of as many as 12 million undocumented workers the companies they work for and the job opportunities of millions of low-skill American citizens. The large number of illegal immigrants raises key economic questions: Do illegal immigrants depress wages paid to low-skill workers? Do they take jobs away from Americans? How dependent on undocumented workers is the U.S. economy? Should illegal immigrants be compelled by law to return to their native countries? Or should Congress hammer out legislation that would allow illegal immigrants to pay some type of penalty yet remain in the United States and continue working?
