I applied for a student residence permit for Norway and I was granted a visa that is valid for the wrong dates. There are two divisions to a semester in the school in Norway. The first is August Block which starts on August 14 and ends on September 1. The second is the Autumn parallel which starts on September 5 and ends on December 22. All the subjects that I have been granted by the school are on the Autumn parallel period (Sept. 5 - Dec. 22) and the problem is that my Schengen visa only allows me to study for the August Block period (August 14 - September 1) since I have been granted a visa valid for July 24 to September 1 only. Could this perhaps be a mistake on their part in that they may have overlooked the dates that I will be studying in Norway? What can I do to fix it? Should I re-apply?
