I used the services of the Law Offices of Rajiv Khanna for my green card under the EB1A/NIW category. I am pleased to say that the firm including Rajiv Khanna and Diane Lombardo were very professional, diligent and prompt. It was comforting to know that I could count on them to deal with the vagaries of the immigration service as I was going through this long, tedious and at times unpredictable process. The entire process took slightly over 3 years for me most of which was due to the long time taken by the immigration service in approving the I-140 and the I-485. My sincere thanks to Rajiv and Diane for helping me through this process.
