I have not been following along on this but thought I would post our good news. We applied for ROC Feb. 25, 2022 and received written NOA
March 1, 2022. Biometrics were waived March 28, 2022.
We applied online for N-400 on March 13, 2023 and received immediate NOA. Biometrics appointment was scheduled for April 5 and our N-400 interview (which we assume is a combo) is scheduled for August 6. Hoping all goes well.
