Just days after the Obama Administration told a court it needed another month to decide how it plans to proceed with respect to litigation seeking to kill DHS' proposed no-match rule, the LA Times reports

No immigration agents descended on Overhill Farms, a major food-processing plant in Vernon. No one was arrested or deported. There were no frantic scenes of desperate workers fleeing la migra through the gritty streets of the industrial suburb southeast of downtown Los Angeles.

For more than 200 Overhill workers, however, the effect was devastating: All lost steady jobs last month and now find themselves in a precarious employment market, without severance pay or medical insurance. It wasn't a hot tip or an undercover informant that helped seal their fates, but a computer check of Social Security numbers.

"A desktop raid" is how the workers' representative, John M. Grant, vice president of Local 770 of the United Food and Commercial Workers International Union, described the scenario.

Overhill, a $200-million-a-year company that provides frozen meals for clients such as American Airlines, Panda Express, Safeway and Jenny Craig, says it had no choice: An Internal Revenue Service audit found that 260 workers had provided "invalid or fraudulent" Social Security numbers. The government took no action against the workers. But Overhill did: All of the employees were fired May 31.

The Social Security Administration has issued these letters in the past, but has not sent the letters for the past few years while it has waited on the DHS regulation to be finalized. The IRS says it regularly issues such letters, but if they have, they must be few in number as there has been virtually no discussion of this within the immigration bar.
