I saw this on one of those talk shows; maybe it was Dr. Phil. They interviewed men who did this, and many of men they showed were middle aged, unattractive men who would never be able to get a woman who looks like that here. One man was ranting about American women not being submissive enough. Another man spent thousands of dollars to bring this woman back. She had health problems, and he spent thousands of dollars getting them addressed. She then left him. These women want to get in for the green card, but when they get here and they see they have an opportunity with attractive, younger guys, are they really going to stay?
Yeah,,, better to marry an American woman. They’ll NEVER marry you intending to leave you when fully vested, and take half your stuff.
