My category is EB-1(employe-based). My Greencard (I-485) was approved in last January in USA side.
My I-824 was approved in Last May and my wife has received the package from Guangzhou Consulate last summer and mailed back. There have been over six months alread.
What is the priority date? Guangzhou Consulate gave my wife a case number. Is it immigrant number you mean? thank you very much for your kindly reply and best wishes to you.
