I recently flew from LAX to Pulkovo with a layover in Stockholm Arlanda and was not able to go to my connecting flight without going through passport control. I was initially told I cannot enter the airport without a Schengen visa, but accidentally ended up in the Schengen zone when an airport employee mistakenly bypassed passport control and took me there by elevator. Luckily, I was able to return airside without a visa.
I'm returning to the US next weekend and was told by my traveling companion (who recently flew back) that she had to go through passport control and re-enter the security checkpoint even though she was connecting to a non-Schengen destination. She's a US citizen.
Am I correct in my understanding that my US green card will allow me to go through passport control without a Schengen visa? I'm a Russian citizen.
There doesn't seem to be a way to get to my connecting flight airside without going through passport control. My connecting gate was not listed on my ticket and I didn't see a connecting gate on my companion's ticket either.
Arriving flight from LED is in Terminal 5. Departing flight to LAX is also in Terminal 5. Both flights are from gates within F58-F69.
