i read a news report months ago - can't find the link right now - that folks get implicated in the much-debated "material support bar" provisions of the immigration law. this "bar" kicks in if the officers detect that you or ur relatives, somehow, knowingly or unknowingly, made a move that somehow was helpful to one or more group(s) that the US government lists as "atankakari". hope you unknowingly did not say "yes" to some questions in the application that asked you if you have ever aided these negative elements in any way.
if that is the case, i am sorry to say, no matter how painful it is for you, that you are in deep shit for the long haul.
good luck.
