I have a German national visa that will take effect from March 1, 2017 up to August 31, 2017. I want to arrive there as early as possible, so I'm taking the earliest flight which is just 20 minutes after midnight, that's early on March 1, 2017. However, I'll surely pass by the Immigration Officer before midnight so then still February 28, 2017.
Will they let me board the plane or will that be a problem?
