US Immigration from Hungary

Hi Everyone,

My i-824 form was received by USCIS on June 16, 2020. I had to submit this form because we had to adjust our approved i-130 from AOS to Consular Processing due to unforeseen circumstances.

I received my correspondence from the Potomac Service Center, yet I can't find anywhere that Potomac handles i-824 forms (let alone the processing times). Is it possible there's some mistake? I thought I would ask here before calling USCIS for more information.
