I have Russian and US passports. Is it a big no-no use them both on the same itinerary?
Here are my details:
I fly from the USA -> Germany (Frankfurt) -> Russia.
Germany is tight (1.5 hour) layover. I will not leave the airport.
I must enter Russia on a Russian passport.
I have a feeling I'll have a more annoying experience in Germany with my Russian passport than my US one, so I was thinking of using my US passport to leave the US, use it again when I layover in Germany, but present my Russian passport to the Russian authorities once I reach my final destination.
Thanks.
