Thanks for sharing this! I am in the same situation but for an original divorce certificate. Interview was Oct 6th and the original divorce certificate arrived at the sorting facility the following day. I also received a similar e-mail reply on Oct 21st in response to an e-mail I submitted alerting them of the document arrival. We had no request for the DS form and no request for additional processing on the 221g. Hoping they will follow a similar timeline, even though I wish there was a more efficient way they could accept a single requested document...
