May I suggest a foreign bride who has not been corrupted by Western "culture"?
With mass communication where are you going to find a pool of women that have not been "corrupted" that you can meet?
VAWA allows victims of domestic violence to be naturalized even if they do not stay married.
If you find a chaste kind honest woman marry her, but don't think foreign women are less corrupted in general or you will not be vulnerable to someone unscrupulous using the system for their own gain.
Where are these good Catholic families turning out nice girls? I know Catholic women who only wear long skirts and are chaste themselves but are not vigilant about protecting their teen's chastity.
