This question already has an answer here:
In my Schengen VISA application, I have mentioned Germany as "member state of first entry" and provided the itinerary of a Lufthansa flight which goes from Delhi to Berlin via Frankfurt, but due to the cost factor, I want to book Finnair now which transits through Helsinki. My understanding is that since I am entering the Schengen area in Helsinki I will have to go through immigration there.
Will it create a problem because I have mentioned Germany as "member state of first entry" or will it be fine?
Can the immigration officer look at my VISA application?
