From NBC => Local FO => NBC again
My EB1A I-485 was initially received at the NBC in Early April, Biometircs at the end of April and then a silent update at the end of May. After the silent update, I chatted with Emma Live Agents and 3 of them consistently said my case was at the local FO (3 separate weeks in June). This week, I chat two different Live Aganets and they said my case is at NBC and interview is waived. I also called the USCIS hotline and a man says my case is at NBC and interview is waived.
Does anyone have experience with NBC to FO and back to NBC experience? If yes, how long did it to to get approval or if you can share your timelines.
