Based on your post, I guess you confuse check-in to your flight out of Russia with the Exit procedure. These are 2 completely different things and just use the passport you have to use. NEVER show 2 passports at an immigration booth, that's just calling for trouble...

Does anybody knows the answer to the last question? Do Americans get questioned when they enter their own country? In mine they just read your passport into the machine, stamp it and let you in...
