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.
Seamless working thru the process from my original visa extension and then filing my status change GC. I was on L1-A and status change to GC. Very professional office and timely responses.
I had a chance to work with Rajiv and Diane. You won't complain working with them because of their timely response and professional approach.
Overall a very good experience working with them.
Thanks.
