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 S Khanna's Law Firm, based in Virginia, is working on my Green Card. I should tell you that I am extremely happy with their service. I have never gotten a chance to speak to Mr. Khanna but I have been 'constantly' in touch with one of his staff, Homa Naderi. She is simply the BEST!! Goes the extra mile to get the job done. Very pleasant to talk to. Someone whom you can count on as a friend. I would first recommend you to visit their website before contacting them. The have a fabulous website, www.immigration.com . It has got a wealth of information ranging from the legal fee structure to the latest news on immigration policies, status, etc. If you decide to go with them call their office and do insist for Homa Naderi to be your point of contact. She will make this long-hard-laborious-US-Visa-pilgrimage a pleasant experience. Feel free to call me or email me if you have any questions at 972 571 1882. Krishna
