My I-129F application was approved, but between my petition submission and approval date, my beneficiary moved from Japan (where she was in school) back to her parents' place in China. I submitted a letter to USCIS indicating a change of address, but that I received the approval notice the next day, so I know USCIS did not receive information of the change in time to do anything about it. However, I did include in my supplementary documentation an indication that she would be moving, and the final address she would be living at. I also listed the Guangzhou consulate as the preferred case processing location on my I-129F form. The NVC apparently ignored my request, because my case was forwarded to Tokyo instead of Guangzhou. Big problem!! She now needs a Japanese tourist visa just to get back into Japan (not easy to come by if she's Chinese and not part of a tour group). What is the best way to ensure that the case is quickly forwarded from Tokyo to Guangzhou where she actually has a chance of attending the interview?
