Just posting to say I filed my N-400 on 16th Nov, 90 days early of my 3 years anniversary of becoming a LPR, under the spousal route. Filed online, and received my receipt notification almost instantly, just stating that next step is biometrics appointment.
I am in Central Ohio, and wait time are reported to be about 7 months.
My receipt number starts IOE-96-585 so a little out of the range of others according to the online tracking tools like this: https://hilites.today/uscis_cases/ioe-stats and this: https://www.casestatusext.com/forms/N-400/IOE-LB
Good luck everyone!
