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.
I am very satisfied with the services rendered by Mr Khanna and his colleagues. They have been professional and quick to reply to most of my emails and calls. I was not very involved with my Green Card process as my work is quite hectic so it was specially good to have people who are abreast of rules and regulations. They had the foresight to indicate CP on my I-140 application which saved me at least few months. I strongly recommend Mr Khanna to anyone who wants to get their GC process done in a smooth, streamlined manner.
