How these rules would work:
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.
The expected regulations would give employers a fixed period, perhaps up to 90 days, to resolve any discrepancies between identity information provided by their workers and the records of the Social Security Administration. If workers’ documents cannot be verified, employers would be required to fire them or risk up to $10,000 in fines for knowingly hiring illegal immigrants.
Immigrant rights groups and labor unions, including the A.F.L.-C.I.O., predicted the rules would unleash discrimination against Hispanic workers. They said they were preparing legal challenges to try to stop them from taking effect.
Would these lawsuits succeed? What else could be in store?
