Quickly, the " female" (the bait) falls in love with her Internet acquaintance, and shortly after " she" begins to plan her travel to see her Mr. Money issues arise, and, reluctantly, the bait asks the gentleman to help "her" with money for her visa and tickets.
Very often, the bait tells the guy that she has a work offer in his country, and she would be able to pay off the loaned money to him quickly.
And this mastermind is not at all who you think (s)he is... A scammer usually finds a set of pictures of an attractive girl 18-45 years old female (or, if the scammer IS an attractive girl, she uses her own pictures) and places personal ads in as many international dating catalogs as possible.
However, the duration of the "set up" phase varies significantly.
The longer the set up phase, the higher is the scammer's probability of success in obtaining the money.
Once the fact that the scammer is "deeply in love" is well established, the scammer begins the real preparation.
She will tell that she has found out everything she needs to do to receive a tourist (work, student) visa.
She will be all bubbly and excited about the opportunity.
