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.
Mr. Rajiv Khanna, Mr. Kunal Sharma and the rest of the team have been very patient and extremely supportive.
I had filed for my immigrant visa through my spouse, and it was quite complicated. Couple of the other lawyers we spoke to said that there are no chances in winning this case, but Mr Khanna was firm, that the fundamentals are right and thus we have a good chance. Finally, after 2 long years, my immigrant visa has been approved.
What impressed me the most is the Mr. Khanna would immediately schedule an appointment (no charge, of course) every time there was some news from the immigration office or from my side. Even during the final stages, I had asked him a few questions regarding my DS-260 as i was very nervous, he scheduled an appointment immediately and told me exactly what to answer in each question. They made me feel as if I was their only customer. Excellent effort and care for each case by the team, and I would surely refer his firm to everyone.
