Applied for I-751 at the start of the window proceeding 90 days prior to expiration of conditional GC in December.
Left for international travel in beginning of January right after application for I-751. Arrived back to USA Jan 27th, and found in the mail the I-751 and a biometrics for Jan 26th, day prior.
Went to multiple field offices attempting a walk-in during slow periods towards end of day and rejected every time at all of them.
Called USCIS number and requested a reschedule and provided reason and uploaded proof that I was out of country entire time and came back 1 day after biometrics was scheduled.
30 days passed, and no reschedule.
Call again, and requested it again and was told that sometimes they don't review it and don't get to it in the first 30 days but will definitely in the the next 30 days.
GC expires on 3/24. I am leaving on 3/7 out of USA until 4/14 as of right now.
Will have neighbor monitor mail and will now monitor online account now that I have this case added to online account.
I am assuming that the only correct course of action is that if there is no reschedule notice in the mail by 3/23 in my mailbox, that I need to take a flight on 3/23 back to USA since if I return back after that I could be in a precarious situation due to the possibility that the "case abandoned due to no biometrics appt fulfilled" at any time and no PR status after 3/24.
Correct understanding?
What a headache over 1 day missed biometrics, but stupid me for not thinking to have neighbor watch mail for USCIS while I was gone in January. Didn't except it so fast.
