Mark,
It all comes down to the fact that if you are her sponsor, and if she gets any documentation from the consulate that she doesn't understand, she would contact you anyways. This in turn also shows proof of a relationship as you guys are sharing information. Why bother adding another layer of paper work to your claim? Especially, from my view point, if you are her rep and handling every communication, I would think it would cause a shadow of doubt that maybe this is an arranged marriage for a business purpose. I think the two of you working it out together is better evidence.
As an example, when my wife moved to a new place, I was the one who sent a change of address to Hong Kong. When she received the letter demanding a court document to prove her claim of sole custody of her child in 45 days, I sent an email to the consulate saying that her scheduled court date to hear her case was not scheduled until 3 months later; far past the 45 days she was granted.
In fact, that is our latest update: We sent the court document, notarized and translated the first week of July and now waiting to hear back from the consulate. The 18 of August marks 26 months processing since Hong Kong received our case file
So hopefully our next letter will be a request for her medical redo. Then I will think we are near to the end. I worry the next letter will instead ask for new copies of her passport since it expires this month. We have been proactive and she went and applied for a new passport, which once she receives it, we will forward a copy of it to the consulate.
OOhh and one more thing, no matter how it turns out for you Mark, I hope you share part of your trip with us. And please, post pictures, as we haven't had a new member for some time now sharing with us their maiden journey. And we like pictures of Asian Maidens
