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.
