According to the San Francisco Chronicle
Sen. Dianne Feinstein attached a farm guest-worker program to the giant Iraq spending bill Thursday in a last-ditch effort to remedy a shortage of workers in California's produce fields as the federal government continues to crack down on illegal immigration and the political climate proves hostile to more sweeping measures...What the bill will do is give them legal status for five years with no promise of permanent residency or citizenship. I don't think anyone honestly believes that once "they come out of the shadows and play by the rules" that they will be deported at the end of the five year stint. Many of them will have children with U.S. citizenship during that time.
Her addition to the Iraq spending bill would give temporary legal status to 1.3 million farmworkers over the next five years, but it would provide no path to citizenship or permanent residency. It passed the Senate Appropriations Committee 17-12 on Thursday.[Feinstein, Lofgren push for immigrant workers, May 16, 2008]
Expect to see this "five year amnesty" come up in the next "comprehensive" measure.
