I have a Schengen visa issued by the German embassy, and it clearly states that it's valid for all Schengen states. I have a round-trip flight booked to Berlin, but my itinerary includes a 2-hour layover in Vienna, where I will change flights before continuing to Germany.
The layover in Austria is solely because of the flight itinerary, and I don't plan to visit Austria first. I've read that you are supposed to enter the Schengen area through the country that issued your visa or is your main destination.
Given my layover in Vienna, will I face any issues? Is it okay to have a layover in Austria before heading to Germany, or should I change my flight to enter through Germany directly?
Thanks for any advice!
