This question already has an answer here:
I am applying for a Schengen visa for a 10 day business trip in Spain + France + Germany. Spain will be the visa issuing country (being both the point of entry & the largest chunk of the trip). All the docs etc are in place and I've had previous visas so barring any unforeseen problems I should have that visa soon.
Now after the trip is done I may go and visit a friend for another 3-4 days in Italy. But that isn't sure yet. But will be decided prior to entering EU. I just don't want to delay the application for the business visa for this.
Supposing I have the first visa but then want to tack on 3-4 more days can I just apply to the Italian consulate & get another visa; thus covering the entire duration of my trip but in two separate visas?
What other options do I have?
Note, I'm not asking for ways to extend my visa after I have landed in EU but before the trip starts.
Its only a matter of 3-4 days but with the authorities issuing very tight date-windows the first visa may not suffice.
