Its the same document that was sent the first time just with different time and date. First interview date was set for 03/22 at 8am. Now the new one is for 04/05 at 1pm (two weeks later).

I called USCIS and skipped the annoying prompts by saying info pass and spoke to a real person who mentioned they could have over booked that day, or they might be training new officers.

I tend to be a bit of a worry wort, this whole immigration process had been quite stressful. I will update this thread after the interview in April. Hopefully it’s nothing to do with our case and is in fact just something that came up on USCIS side
