According to an official alert, December 1st will mark a big change in how Norwegian passport applications are being handled. Beginning on that date, it will no longer be possible to apply for a new passport through Honorary Consulates, including the one in Minneapolis.
That being the case, anyone who has a passport that expires in the next couple of years is being encouraged to contact their nearest Consulate for passport renewal before December 1. Thereby avoiding the inconvenience of a trip to one of the few remaining consulates in Washington, Houston, New York or San Fransisco.
A full explanation of the change can be found here at the Norway.org website.
