Hi.
What_happen,
I have heard of cases where notices arrived one or two days apart. When I went to Baltimore and officer checked my A# for interview and told me late October, I then asked what about my wife, she refused to check it and said "They go in one pack." So, I would say it is the mail and hopefully you will get it today or tomorrow.
gcsept18,
Could you pls check for me if they require photographs from you. More accurately, have they checked the "Two photograps" item on the checklist?
Cheers
