回複：I-485 6月7日寄出， 6月22日支票cleared

Could you share what is the street mailing address for TSC? I remember Express mail has to use street address, NOT PO box number. But only P.O. Box number appeared in my I-140 approval notice from TSC. Thanks a lot.

I called USCIS customer service, and was told that I-485 based on a pending or approved I-140 should be mailed to the service center where you i-140 was processed.
