Interview was moved to a different district, although I didn't move out of district
Here is my short story. Me and my wife applied in March, 2016. We were scheduled for interview in SF district for August, 4. Few weeks before the interview we submitted address change request and later got our confirmation letters. The new physical address is the same city and the mailing address is the different district. Everything remain same for my wife but something wrong happened to my case. It was cancelled and in few days scheduled again for August 30 but in the _different district_ - the Santa Clara district where my mailing address is in.
Rajiv Ji, Glad to inform you that we got our GCs couple weeks ago. It has been a pleasure working with your office for almost 11 years now. I sincerely thank Rajiv Khanna and Prerna Mehta for their excellent support and prompt turnaround with the queries and process related documentation for getting our Green Cards.
