I just worked with a USAF Major Flight Surgeon on an aircraft mishap investigation. He went to college in Russia and medical school in the US. I'm not sure of his commissioning source.
My son is a Swiss-American, born and schooled in Switzerland, and he is now attending USAFA. His main hurdle was the nomination. I am sure your Russian language skills will prove a great plus in your favor. Good luck!
Wow it's great to see another American-Russian applicant. I was born in Moscow, and immigrated to the U.S. when I was about a year old. Where do you live?
