Hi all, I am not sure exactly the best place to post this. We are getting ready to go to DC to get my last name added to my wife's name on her Chinese passport in the way disussed here (also known as). There are two Chinese Embassy buildings in the DC area. I have been to the one where you get visas to visit China, but I don't know which one we should go to to get the "also known as" added to her Chinese passport. I have tried to find the information on the web site. I just got the embassy number and will call them Monday, if necessary but, has anyone here gone to DC to do this? Is an appointment necessary? Can it be done with same day service? Thanks
