We are in the Same Boat , it happens to me Because of two Reasons , We moved , Changed of Address & My Son Emter in K-2 Visa, but still hoping to have it soon, God Bless.
I haven't received my GC because they sent it to our PO Box instead of our home address and we haven't check it for 2 weeks. When I checked the date, it was sent since August 11.
