The status will say "SP Processing" if it is in OCR. "In Verification" means that it is (1) in verification or (2) the binder has not been opened by the preparer since verification (example: I verify and send to pool and it is still sitting in the pool, it will still say "In Verification" even though it has been verified.)
The blank status means it has past the OCR, verification, and binder creation step. They are already in review or being prepared
