You think that you are offerring a good deal by buying a marriage/green card with $100k? Do you know that the other person would put her immigration applications/green card/citizenship in the danger of criminal prosecution/ denaturalization/deportation in the rest of her life? You are totally off the road of your life now. Try to reach your goal, either green card or family, by investing something other than money. If you have too much money to spend, donate it to some charities.
