In a new effort to crack down on illegal immigrants, federal authorities are expected to announce tough rules this week that would require employers to fire workers who use false Social Security numbers.
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.
