Interview Report:
1 US LPR who applied in April 2020, approved same month - had scheduled interviews/automatically been canceled multiple times during the pandemic. No issues, though was oddly asked if we had our birth certificate at the beginning--didn't have it, wasn't an issue. Standard questions, any additional countries visited, any other citizenships, proof of address (had changed between application and interview, not an issue), email address. Was given a pamphlet regarding NEXUS, which was 99% focused on customs issues.
1 naturalized USC-was asked for the naturalization certificate, didn't have it and was told to email it, did that and was approved a day or two later after calling the office and speaking to the agent who did the interview (probably could have waited a few days). This was a member who applied in 2019, scheduled an interview that year and the next, but despite it being more than 720 days after the first conditional approval, had no issues getting this interview and completing it. This was also a member who had an agricultural violation in 2013ish, and was initially denied, then conditionally approved after reconsideration (you can probably see information on that in my history). Was asked about that at the interview and answered truthfully. I think since it was a one off thing with no other immigration/agricultural issues is why they were allowed a reconsideration approval in the first place.
Was told by the Canadian officer that any passport updates done on the TTP website does in fact go to the Canadian side. I had been concerned since many people here said they were told the opposite and needed to go in person to update the passport for the Canadian side
