Our NOA2 was on 10/21. I sent an inquiry to NVC on 11/23 to see if they've received my case from USCIS. A week later on 11/30 I got a response that my case was received:.
"Dear Sir/Madam:
The National Visa Center (NVC) recently received your immigrant visa petition from U.S. Citizenship and Immigration Services (USCIS). Your petition is now waiting for data entry into our systems.
Since your case is not in our systems yet, we cannot make updates.
As soon as your case is in our systems, we will send a Welcome Letter and instructions. Then, if you still need help updating your case, you can contact us by using one of the methods listed on https://nvc.state.gov/ask.
For current processing times, please visit our website: https://nvc.state.gov/timeframes for English or https://nvc.state.gov/plazos for Spanish. If your petition was approved before the dates NVC is working on, please resubmit your inquiry.
You can also begin to familiarize yourself with the documents NVC will request at that site."
