I had my interview Dec 8th 2022, and my application was approved on the same day. It showed "Oath Ceremony will be scheduled" on my USCIS account. It has been 9 weeks now since I have been waiting for the Oath Ceremony Letter, but I have heard anything. How much longer should I wait? Is this a normal wait time? I am in Peoria IL and USCIS office was in St Louis, MO. Anyone had a similar case who filed for N-400 in Peoria IL? I am hoping I am not going to wait for more than 3 months to take the Oath Ceremony.
