So we submitted my wife's AOS (I-485, I-765, I-131) packet on 05/23/22, she had her biometrics appointment on 06/27/22, we received an RFE for the I-864 on 06/13/22 (most likely for a form that was out of date), we returned it on 08/24/22, and we still haven't heard anything whatsoever since then; her USCIS account just says the response was received as of 08/31/22.
This is very frustrating and her still not being able to work is becoming a problem. Does anyone know if it's normal for updates to take this long, or should we call them to try to get an update?
