My wife and 11 year old daughter received their green cards within 7 days after the AOS interview. The Councilor approved on the spot which is not always normal. She was very nice. They had special arrangements for the interview because of COVID. The questions were asked from a room next to us via Video like Zoom. We made an appointment to get the daughters SSN. My wife and her daughter had a specific time for the SSN. Needed all original papers. BC, Passport, green card.
now wait for the 2yr AOS interview.
