I am traveling with a US PP, connecting through Istanbul to Budapest in Sept with a very short connection time. Although I will not be leaving the airport on my arrival, I WILL be returning by air from Bucharest to Istanbul about 10 days later, so I will need a VISA. My questions:
Is a Visa needed if you are not leaving the airport? (making a connection?)
Should I get a Visa online ahead of time to save time once on the ground if we would need one when arriving to make a tight connection?
If I have the online Visa and "use it" (show it, or do I have to give it up?) when we arrive in Istanbul to make the connection, will I need another (or a copy) when I arrive 10 days later on a plane from Bucharest?
Lastly, does anyone know how long the Visa is "valid"? or do you specify the length of time you would like?
