I would strongly discourage fishing in international waters. The basic problem is that there is a huge incentive for such women to pretend interest when what they really want is the green card. The balance of what each brings to the table shifts considerably once the permanent green card is issued.

Note that this is *not* to say that international relationships can't work--I've seen some that do (including my own) but I do not know of one that didn't involve one person being in the other's country already (although I would not rule out both people being in a third country, I just don't know any such.)
