Three weeks ago, President Obama extended the deadline for the Federal government budget, allowing all Federal agencies to continue operating.   At midnight tonight, the extension expires. 

Although Congress is trying to work through budget issues and provide funding for the federal government to continue operating, the Department of Homeland Security has confirmed that in the event of a government shutdown, E-Verify will be impacted and will not operate until the budget issue is resolved.
 
It should be noted that the shutdown of E-Verify will not change your I-9 responsibilities. If a shutdown occurs and E-Verify becomes unavailable, employers must continue to complete Form I-9s in compliance with the law.  The required information will need to be submitted to E-Verify when the system is operational again.

To stay compliant, People 2.0 recommends that any independent staffing company that uses E-Verify should keep the I-9s of newly hired employees in a separate folder from their other I-9 files (but still kept in a locked cabinet or office) until E-Verify becomes available again.
