OK- look. Here's the deal. If a woman approaches you, either in person or on the net and she's from any Eastern European block country, or any third world country, or anywhere else and she's NOT an American citizen, WATCH YOUR BUTT. These scams have been going on so long and in such great numbers that it's ridiculous to even put yourself in that position, much less actually get taken.(By the way, there are entire websites devoted to tracking these ladies and their identities)
The truth is that you're an American citizen. And even if you're the fattest, ugliest, brokest, most ridiculously pathetic guy on the block, you still have one thing that's worth gold the world over. American citizenship and the ability to sponsor a visa. So, don't be surprised, you idiotic, fat, virgin, 50-year old dimwit, when the girl who looked like an 18-year old supermodel, but didn't speak much English, who miraculously said she loved you, even though that's the only thing she ever said that you understand, turns out to be lying. You thought,in the back of your naive mind, it was too good to be true and it is.
I'm all for studying and being knowledgeable about such things as law, language and custom but at some point you have to believe that this is simply a common sense issue.
