I fly from YYG to the US nonstop and yet quite often some of the more senior CBP employees don't know that YYG is in Canada. I have not seen any such issues with Russian flights to the US. Very few, if any, of the youngest CBP employees may have been born after the dismantling of the Soviet Union but old nomenclature can be rather sticky when it comes to older folk.

The OP is unlikely to have a problem with CBP because of a Russian visa, although it may be possible that questions could arise related to declared residence or with matters tied to residence.

I know some Scandinavian attorney who live and work in Russia and come to the US for vacation. They haven't had a problem. But none of them have been trying for Global Entry type of allowances for the US AFAIK.
