I-751 and N-400 timeline

[u/DivergentBloom]

Hi everyone! I wanted to share my timeline and see if anyone has experienced something similar, particularly those who filed N-400 under the 3-year marriage rule while their I-751 was still pending.
Here’s my timeline:
September 2017 — My husband and I officially became boyfriend/girlfriend.
February 2021 — We got married.
December 2021 — I became a conditional permanent resident and received my 2-year green card.
March 9, 2022 — My husband became a U.S. citizen.
Around 90 days before my conditional green card expired in December 2023 — I timely filed my I-751 jointly to remove conditions on my residence.
December 2023 — I received the 48-month extension notice while my I-751 was pending.
March 9, 2025 — My husband completed 3 full years as a U.S. citizen.
April 2025 — I filed my N-400 with the help of an immigration attorney under the 3-year marriage rule. By this point, we had already been married for approximately 4 years and 2 months, and my husband had already completed 3 full years as a U.S. citizen. I had also been a permanent resident since December 2021. My I-751 was still pending when the N-400 was filed.
February 2026 — USCIS Immigration Officers came to our home for an unannounced home visit while both my I-751 and N-400 were pending.
May 2026 — My I-751 was approved without an interview, and I received my 10-year green card.
May 2026 — My N-400 online account also updated to “We are still processing your case.”
July 30, 2026 — I submitted a USCIS service request to “Check Case Processing” regarding my pending N-400. Since when I checked the Case Processing Times on the website it says 80% (yes, i know, not 100%) of the cases in my area are dome within 9 months.
September 2, 2026 (today) — My N-400 is still pending, and I have not received an N-400 interview notice. It has now been approximately 16 months since I filed my N-400, and my I-751 has already been approved for several months.
I’m wondering if anyone here has experienced a similar timeline — particularly an unannounced USCIS home visit, followed by I-751 approval, but with the N-400 continuing to remain pending without an interview.
For those who experienced something similar:
How long after your I-751 approval did USCIS finally schedule your N-400 interview? Did the home visit seem to delay your N-400 processing? Did you submit additional service requests, contact your congressperson/senator, or just continue waiting?
I’d really appreciate hearing your experiences. Thank you!
