USPS delivered my application to INS MIXED

I sent my renewal last week through USPS with 1day Priority Mail Express to:
USCIS
P.O. Box 5757
Chicago, IL 60680-5757

This was last week. On Friday it was delivered to CHICAGO, IL 60680 to INS MIXED. And signed by S MERAZ.

My question is, is this happening to anyone else that sent there's to the Chicago location?

I have not receiving any email or text yet.

Oh Crap, Steven Meraz works as chairman of the National Alabama Minuteman Club.

Did you send a personal check? If so, check your bank account constantly for when, and if, the funds are withdrawn, also who endorsed it.

Withdrawing the funds is perhaps the first thing USCIS does when they just received an application. So that should give you some clues.

Good luck!
