I have been to Europe before but never had to deal with a visa so far. Will I have to show it at my layover in Istanbul? (I have a layover in IST on the way to Munich, staying in Germany a week and then on to Eastern Europe and only visiting/stopping in IST on the way back).
Will I go through passport control only in Istanbul when I am on my way to Munich?
Will I go through security only at LAX or again in Istanbul? I am flying with Turkish Airlines for all flights.
On the way back I have a direct IST-LAX flight, will I have to show the visa paper again as I leave?
