Is that OK for my I-485 delivery status?

Status: Notice Left

We attempted to deliver your item at 12:11 PM on August 7, 2007 in MESQUITE, TX 75185 and a notice was left. It can be redelivered or picked up at the Post Office. If the item is unclaimed, it will be returned to the sender. Information, if available, is updated every evening. Please check again later.


I use USPS priority to deliver to TSC, P.O.BOX 851804, very worried...
