Janney Good point, many other nationalities also do the same, the reason why only Philippines highlighted in the main post is cuz some of them can't afford to fly back just to have some paper works done and some of these girl try to date a man who is either already married or have no plans for long term relationship, at the end they are just left alone to deal with the cost and legal risk. I have even met some western men who keep them in home and pay monthly salaries.
