I had a Schengen visa issued by France but did not visit France; instead, I visited Norway. I was under the impression that holding a Schengen visa from any member country allows travel to any country within the area. (This is against visa rules. I couldn't conduct proper research and applied based on my relatives' advice, which may fall under visa shopping. Another reason I chose France was that I was told it's easier to get a visa from the French embassy).
Now, I want to know if I apply for a Schengen visa again, will I face rejection? If so, under which category would the rejection fall? Could it result in a ban? I am concerned about this because I need to travel to Schengen countries for work in the future.
