On December 6 and 7, we got the card order emails. My daughter and I got GC last week, but my wife have not got her card until yestoday.
The reason is that when I changed all three person address, my daughter and I got update, but my wife have no update. So her card and approval letter are mailed to the old address. Fortunately, we apply postoffice transfer service. They transfer my wife's card to my new address.
