On August 17th I need to visit a conference in Germany. The problem is that I already have a Schengen visa valid until 9th of August.
I might not be able to get a new one before my flight to Germany, because, as far as I know, embassies take at least a week to give visas (also, airlines require visa information several days before, so the "window" is less than a week). The one I have now was given by the consulate of Spain.
I am a citizen of Russian Federation and I live in Moscow.
Is it possible to apply for a new visa before the one I have expires?
I've tried googling, but the data I found was full of contradictions.
