AC21 Receipt Confirmation

[Sabu]

Does anybody know, how to confirm that USCIS received the AC21 Letter? Will the last updated date for I-485 petition, change after USCIS receive the AC21 letter?

Thanks,
Nanshi.

----NO, I have not read that they change anything online status or send you any letter after you send AC21 letter, it is attached with your I-485 pending file
Thanks,
