Had N400 Interview, now being asked to File I-751 AGAIN

[Fsebastian 0]

Became permanent resident in 2007 and had conditions removed (received 2nd green card) Now I'm being asked to file I-751 AGAIN. How is this even possible? Received request 10/04 and have to submit I-751 plus fees by 11/03.

Is there any channel I can resort to resolve this? There are no appointments available at my local offices until the end on the month. What do I do???

schedule apointment at the end of the month and prepare package for i751. the 31st is a Monday so if you do not have in writing that it was in error send in your package on the 1st of November next day so it arrives in time.

Ok so I became a permanent resident through my fathers application on 7/25/07 and received my first green card despite some issues with my father and I being confused by uscis (we have the same name). The first green card says: resident since 7/11/08. Card expires 7/11/10.

My dad then submitted our I-751 and his conditions were removed on 11/16/2009. Mine were as well because I received my second green card which says: resident since 7/25/07. Card expires 11/24/19.

Fast forward a few years and I submit my n-400, do biometrics, do interview and pass exam, and now I get a letter saying I need to resubmit I-751 because according to them my adjustment occurred more than 90 days after my father's conditions on his permanent resident status were removed. "Hence I cannot ride on the principal I-751."

How does this make any sense? I scheduled an info pass appt but it's not my local field office so I'm not sure they can even help. I don't know how to proceed from here.
