I think you said before that local office is away from your place of residence but if you are too concerned you should do an InfoPass. We have been dealing with immigration since 2003 and I hope this is happy ending for us.
So, my wife's 3 year anniversary was 1/26 and the interview was 1/24.
She was approved but was told official approval will be completed on 1/26.
On 1/24 afternoon we got the status update that RFE letter was sent. Requesting an initial evidence seemed to be a temporary status that is used to place applicants who were approved before their 3 or 5 year anniversary in.
On 1/27 another update was posted that they received the Evidence (which we never sent since we never received a letter) and they are reviewing it.
Of course, the status is saying they are reviewing since 1/27 but we never received anything since then.
Problem for me is that we were assuered we will do the oath soon. So we booked our travel flights already.
I just want this to be done early so we can get a chance to get all paperwork for the passport done and submitted in time.
