Thanks for quick response, just to make it clear: On 06.30.21 You have received email from NVC saying that your case Documentarily Eligible ,and on 07.06.21 You have received another email from NVC saying that your immigration interview has been scheduled,was it like that ,and I assume that your Mom interview was on August 2021 cause they send notifications one month prior to the actual interview date ,I have received email for my Mom's case from NVC with DQ on 05.18.2022 .Kinda anxious.
Regarding $220 immigration fees and GC ,My husband received his SSC two weeks after entering US ,and received GC 4 months after entering US it was in 2021 !!
