Mr. Khanna is extremely knowledgeable. In my personal experience he's been the only lawyer to know the legal intricacies as well as he does. In my case one tiny detail that he caught made such a huge difference from me being "out of status" to being in "authorized period of stay". He is the person to go to for any immigration advice, and on top of that he is really wonderful to talk to.
