I have a Schengen visa valid for 30 days with 14 days stay. This was as per itinerary planned by me. In my return trip I will be traveling from Frankfurt to Bangalore via Paris.
Suddenly my connecting flight from Paris to Bangalore has been cancelled and I have been accommodated by airline in next day's flight. But my visa is not valid for that additional day and it will be 15th day in Schengen area.
Please advise.
A Schengen visa can be extended if departure is prevented by "force majeure" such as unexpectedly closed airports (see the link in the question that was tagged as duplicate). The reason why I write this answer is one important addition: The application for an extension should be done before the visa expires. If you are already at Frankfurt airport, you might ask the Bundespolizei if there is a visa office open on a Saturday evening.
