The US Department of Homeland Security's Immigration and Customs Enforcement Agency revised their regulations to impose penalties on employers who fail to take prompt and proper action when notified that social security numbers provided do not match government records.

US law requires employers to maintain records that the identity and employment eligibility of all employees who work have been verified in the legally mandated manner. US law penalizes employers who employ foreign nationals with the knowledge that they are unauthorized for such employment in the US. The maintenance of proper employment verification records can be used by an employer to show the employer did not know the foreign national was unauthorized to work in the US. The new rule removes that protection in cases where the government notifies the employer that the social security number provided by the employee does not match the employee name on government records, unless the employer makes a timely effort to correct the record.
