David, yes that is what I'm saying, the way the U.S.government has set up the Visa process is that they don't and won't interfear with the Embassy in China, what they say is the way it is and it seems to depend on if the Visa officer got laid the night before or not and they also seem to change the rules when ever they think you have it thought out, your wife can go to the visa interview with 100 other women and men to get the visa and not two of them will have been asked for the same things or given the same questions as any other person that day, some will be asked for every thing from what you do for a living to seeing recipts for everything the two of you did for the entire time the two of you have known each other to someone being asked two questions and thats it, no photos, documents, nothing, but the U.S.C. will have to have a permanent address in the U.S., do I think this is good, No, do I agree with you, on some of this Yes, can anything be done about it?, not on your life, and if you try to make a stink about it, you have to set up an appointment to talk to someone so they can say, " thats the rules", we as the U.S.C.'s can't even be with or wives, on the same floor let alone be in the same room during the interview, we have to wait in the coffee shop down stairs and look at the faces coming down the stairs to see if they passed or not.
If your S.O. happens to get a pink paper then they have a visa that will come in the mail, if the have a white paper then its no visa, or a blue paper then its not yet, they want something to be proved, but try to find out what that is for the blue one and they won't or can't tell you, they will mail it to you, for the white its usually " a non-bonafide (?) relationship"
Forgot, you can use a friends address as long as they can give you recipts for rent, or you parents house number and that will be okay, they will not take a P.O.Box number, the U.S.C.I.S. needs this to be able to mail you all the information and forms they need you to have and fill out.
