[JURIST] US Senators Jon Kyl (R-AZ) and John Cornyn (R-TX) [official websites] introduced a bill [press release] Tuesday which could force millions of illegal immigrants currently residing in the United States to leave. The proposed bill [text, PDF] includes the adoption of a machine-readable Social Security card system for all US workers to keep illegal aliens from obtaining jobs, tough fines for companies hiring illegal aliens, and more Department of Homeland Security employees assigned to pulling illegal immigrants from the workforce. A rival bipartisan bill [text] was sponsored two months ago by Senator Edward Kennedy (D-MA) [official website] who says the Kyl-Cornyn bill "is not a realistic solution, and won't solve the security and economic problems we face." The Kyl-Cornyn bill has also criticized by the National Immigration Forum [press release] and the National Council of La Raza [official website], the country's biggest Hispanic organization, for not including practical ways for workers to gain citizenship. According to the annual US Census calculations in 2000, there were nearly 9 million illegal aliens in the US at that time with an average of 500,000 individuals added to the number each year.
