After receiving an e-mail request 6 days ago, my wife received a physical letter from Beijing on Aug 23, requesting for her passport and other relevant material we think the Visa office would need. We will include some translated letters and chat logs (previously un-translated) in the same package, along with the passport.
Medical had to be done before sending in the application for Beijing, and it was done. Also, I paid for the Permanent Residency fee when I paid for the immigration application. So hopefully they will have everything to make a decision.
