Thanks to Ginnu and SaiGC.
I filed 485 in TSC. The common address there is,
Department of Homeland Security
United States Citizenship and Immigration Services
Texas Service Center
P.O. Box 851488 - Dept A
Mesquite, TX 75185-1488
Does anyone know what Dept A is?
How do we know that these AC21 will fall into the right place? (recently, I was told that my file has been assigned to an officer)
Gurus, please provide some information.
