Is it a requirement that if a person inquires about the reporting requirements that we file an immediate SAR?
No; asking a question is not structuring.
However, as devsfan's analysis reflects, if your customer has asked questions about reporting or recordkeeping requirements and then conducts transactions that appear to be designed to avoid those requirements, you have to accept the fact that 2 + 2 = 4. The FinCEN CTR even provides an extra box for you to check when the customer has made such inquiries.
