Federal election regulators face a court-imposed deadline this week to decide whether to modify the national voter registration form so Kansas and Arizona can fully enforce proof-of-citizenship requirements for their residents.

U.S. District Judge Eric Melgren has given the U.S. Election Assistance Commission until Friday to make a final decision. The judge has kept control of the lawsuit filed by Kansas and Arizona in anticipation of further court proceedings.

Elections commission spokesman Bryan Whitener said Thursday the matter is still under review.

The commission solicited public comments from Dec. 24 to Jan. 3 on requests by Kansas, Arizona and Georgia requiring the additional proof of citizenship.

If the commission does not respond by Friday’s deadline, Melgren said he would deem the request denied and proceed with the lawsuit.
