re: Ukrainian match-making services--do they all operate like this one?

If I were going to do this, I wouldnt spend time emailing the girl. I would state everything in my first email. Basically tell her that if she looks like the girl in the picture, then we would have a two year trial marriage with an air tight pre-nup. During the two years I would pay for English classes and help her get a job.

If she wants to leave after 2 years ( that's how long it takes to get a green card), then she can go.

If this strategy worked, you could get a new wife every 2-3 years or find one you really like.
