Sounds like a scam to me. They get in the country, then claim abuse and molestation. They won't throw them out then , because to do so would make girls afraid to report it if they were really being abused, or kids molested. It's another case of women's rights groups creating rules for good reasons that then end up being used as scams by others with their own agenda. I.E., she gets him to foot the bill for shipping her over, then has a ready excuse for skipping out on him!!
BTW, Oksana is a cutie, but how come there are only about a dozen names for all Russian girls?
