My understanding is that Russian women make very serious wives, if they decide to marry you.
You have to be careful to not be used.
I knew a guy that after his divorce married only Filipino gals.
“Yeah - I know they only want me so they can be American. But - they are good in the sack and good in the kitchen. It cost’s me about $40k for each wife. That’s about the same price on the lease of a car for the same amount of time. It’s worth it to me. Funny thing is, except for my first wife (American), the other five are great friends!”
Rule 1: If you plan to marry a foreign bride, be prepared to stay in the country and culture which created her. The moment you bring her to the US, and subject to American laws on alimony and child support, she becomes an American woman.
Leave your assets in a place where they are out of reach of her and any "family court" system. If she knows you can be gone at a moment's notice if she turns nasty, it's an incentive to behave.
