General Discussion

The controlling type of guy who can't handle a strong woman or the idea of having a mere female as a partner often talks about having an immigrant wife because she won't talk back.
Likewise, baby princes who don't think they need to deal with the minor BS in life like paying bills, cleaning house, cooking meals, ect., want a Mommy with benefits to pick up after them and schedule their lives while they play grown-up. And they'll look for a woman who isn't a "feminist" or might have desires of her own outside of taking care of a home in exchange for being taken care of.
Both these types of men are also attracted to organizations where they are able to swagger around playing warrior and busting heads without much repercussion or possible hazard to their personal safety.

Immigrant wives are perfect to these types. They keep your house comfy, any kids out of your way, and don't talk back - even if they're "She who must be obeyed" types, their demands generally won't require any change, personal growth or much consideration other than an ability to budget or work extra shifts
