I am an indian passport holder. I applied for and got Schengen Visa Type C, from Belgium Embassy with itinerary Italy - Spain - France - Belgium - Italy (maximum stay in France, port of entry and exit: Rome).
Now I wish to change it to Italy - Spain - Italy - Malta - Italy (maximum stay in Spain, port of entry and exit: Rome). If it is possible, how should I go about it?
The initial part of the itinerary and ports of entry and exit are the same.
