Congrats on getting the notification they are done with administrative processing. Note, the only consulate in China that handles immigrant visas is the one in Guangzhou, so we all have dealt with Guangzhou. As for Embassy, there is only one American ambassador in China, ambassadors are stationed in the capital city of a nation thus the Embassy is located in Beijing, all other locations are considered consulates. Oh cool, that is good to know. Thanks! Wish me luck!
