@ak1408 - I am not sure how did your interview go.
My experience is almost very similar to
Miragee52.
I have been a GC holder since 2011. I applied for citizenship in 2018. My bad time - I was charged with a petty crime in Dec 2018. Yet, I worked with my municipal court and had the case dismissed. In the mean time, I had my interview scheduled by June 2019. I was in the middle of taking care of the crime, so, I requested them to reschedule. I was rescheduled for Feb of this year. Substantial delay is good for me and I took care my case well. I also got the certified copy of my disposition.
So, on the day of interview, I was asked questions about arrest and if I was convicted or not. I honestly answered those questions. I provided them the certified copy. My case was still reviewed after the interview and it was not approved right away. I waited for 3 to 4 weeks. My application got approved on Mar 16th, just before COVID shutdown. I did not get oath letter till mid of June. My oath was scheduled for the last week of June.
Key facts: No conviction; Case must be dismissed be it a dismissal due to wrong charge or dismissal by deferred disposition; No jail sentence at all and if the court disposition simply says, " case dismissed", then, there is no need to worry in applying for citizenship and getting an approval. Even if there is a day jail sentence and case was not dismissed, it is a big problem, though one could be eligible for petty offense exception, more likely, one has to wait for 5 years. If one is not eligible for petty offense exception, do not even think about applying for US citizenship.
