I sent my package on 01/31/2021 (i-485, i-130, i-944, EAD and AP, Self Support Affidavit) Received at the Chicago Lockbox on 02/01/2021 Haven't heard anything from them and they haven't cashed the cashier checks.  Anyone that is in the similar situation than me? I am very concerned that I have not heard back from USCIS.
