A couple of weeks ago my Chinese sister-in-law applied for a B-2 visa to visit the US this summer and she has her interview in Guangzhou this morning (well tonight in the US). I was thinking that it would take several months rather than weeks for her interview to take place after she applied but it all happened really quick. We are pretty confident in her chances for success as she has and can easily prove strong ties to China which will compel her to not overstay her visa. She has and will submit the following items during her interview:
1. An invitation letter from my wife and I in both English and Chinese which gives a brief description of her trip and a pledge that we will provide a traveler's medical insurance policy for her during her visit.
2. Copies of her bank statements showing significant monetary assets.
3. Proof of home ownership in China.
4. Proof of business ownership in China.
5. Proof of automobile ownership in China.
6. Copy of her hukou proving that she has a husband and son in China who will not accompany her on her visit.
I think that those items should be sufficient for success but then again you never know when it comes to dealing with the Guangzhou Consulate.
