Officials said the rules would be backed up by stepped-up raids on workplaces across the country that employ illegal immigrants. After first proposing the rules last year, Department of Homeland Security officials said they held off finishing them to await the outcome of the debate in Congress over a sweeping immigration bill. That measure, which was supported by President Bush, died in the Senate in June. Now Bush administration officials are signaling that they intend to clamp down on employers of illegal immigrants even without a new immigration law. The approach is expected to play well with conservatives who have long demanded a tougher stance on illegal immigration, but could also spur a renewed legislative effort to provide legal status for the estimated six million or so unauthorized immigrants in the work force.
