I was recently at a Deposits Compliance Seminar with the my state Bankers Assosiation. I did ask them about this because my bank has not received anything from FinCEN. They informed me that if I have already made sure that FinCEN has our correct contact information then I shouldn't worry, because eventually, my time will come. Apparantly from what they have seen, there is a reason that FinCEN is not sending these requests to every single bank in the country.
However, keep in mind that this may just be the opinion of two people from the WBA. I would suggest that people take the advice from the BOL gurus and get to the bottom of what is going on. I sure don't want to end up with 150 requests in 1 hour.
