USCIS 有許多辦公室，綠卡申請是如何分配到不同的辦公室的？在大華府地區綠卡的申請，一般會分配到哪個移民局辦公室？
-Normally it is assigned to the USCIS center based on where you live when you file the application. What kind of the immigrant applicaiton you plan to file, family -based or employment-based? You may check the instructions such as I-130 Instructions to see where your application needs to be sent to.
