Well, for my it was a long time ago, but normally the IO will ask you for your ID, passport. IO will have on his/her desk all the package that you sent before; at this time you are allow to add any information that you consider might be relevant on your case. Then after this part is done IO starts asking you questions about your case, like dates, names , cities, organizations, etc....most of lawyers advise to answer only what they are asking, not to use many words...................just go to the point. Also of course go well dressed and bring all the papers that you think might need.
I would like to really thanks a lot for the guidance provided by the law office of Mr.Rajiv during my H1 extension process. In my case it was a double RFE and the whole team worked a lot to get me out of it. Finally got my H1 approved. I can strongly recommend taking services from Mr.Rajiv's law firm as I personally feel we are in safe hands.
We have great trust in this firm and we have been receiving excellent service. We strongly suggest using services of Mr. Khanna for any immigration related cases. We wish them all the best.
