I have a single entry visa to visit Belgium in late October (2 nights). I applied for multiple entry through Belgium, but I only received a single entry.
I also have a ticket booked for a trip to France in mid-November (also 2 nights).
How can I obtain a visa for my France trip?
More info: I didn't know I cannot have a new visa while having unused Schengen visa, so now I have appointment to issue French visa too, for this Friday. What should be my course of action?
