I am planning a 2-3 week visit to the UK, with short trips to Schengen countries before and after. As pointed out, I should be able to apply for a Schengen visa once to cover both trips.
Will the Schengen visa likely cover just the duration of these two trips, or also everything in between? If it also covers everything in between, I might add a short trip in the middle (e.g. to France) later.
When applying for the Schengen visa, my itineraries will include flights to/from the UK. Will they want to see that I've already successfully applied for UK visa, or the proof of flights between my country and the UK?
