A federal judge has ruled that three former Smithfield Packing Co. workers will spend 18 months in prison, along with three years of supervision for immigration violations. Specifically the violation was tied to fraudulent documents that were used to get jobs.
Each individual also will be deported after serving the prison term.

The sentencing was a result of a federal immigration raid in January 2007 at Smithfield Packing's Tar Heer, N.C., pork processing plant, which produced the arrest of 21 workers.

Investigations determined that 18 of the 21 workers were undocumented aliens who had assumed the name and social security numbers of other people. Fifteen of those 18 workers also are being prosecuted
