I just learnt this is the number 1 scam organization in this field - after I received a funny scam winning letter, claiming that I won in the lottery so I need to send my documents to Thailand! Of course, some fees apply too.
So far, having a 10 years membership with USAFIS, and about the 4th now, I haven't received any confirmation number (that my application was actually submitted in the lottery). I do not understand why doesn't anybody take action against these fake services providing organizations?! Thanks.
