Bottom line it all depends on your relationship. If you only saw the person you picked from an online catalog for a week a year ago, odds are you are going to be in trouble if you guys don't communicate in a common language either.
I'll second that. It seems if everything else is in order, the language really doesn't matter. But, if you've had a "short" relationship, better start practicing those questions/answers in English.
If you're a "native" Russian speaker, there should be no problem at all with her speaking only Russian. But, if you guys communicate in the "little bit of Russian" that you know and the "little bit of English" that she knows, then once again, she better start practicing.
However, you said she's been to the U.S., so if you guys had a pretty long "courtship" and met each other several times and all that, then you shouldn't have to worry at all about the spoken language.
