I am in France on a schengen tourism visa on my South African passport. My plans when I applied for the visa were to visit france, Germany and the Czech republic. Is there any reason why I would not be allowed to make an adjustment to my itinerary now that I am here and make a side trip to Switzerland on this visa? The reason for this is to break up a long train trip between Germany and France.
Family of mine say that they had problems because they required schengen and a separate visa for Switzerland. This seems contradictory to the schengen idea of free movement and everything else I've read. Just in case, can anyone confirm this for me?
