erich - Interesting, I haven't heard of a firm requesting info unless there was a serious red flag. The 2 questions I have are - 1) what is your age and 2) what did you put as your net worth?
My guess is that those 2 don't quite add up to them.
You have a choice now of admitting you fibbed and see what they do or time to try a new broker. I suggest
Open ECry.
