I received my H1B Extension as well as my wife’s extension of stay with Rena Waddell, Law Offices of Rajiv S. Khanna, P.C. Rena Waddell is an expert on immigration laws and we never got any problem or incompletion about the paperwork done under her supervision. She is very co-operative and would return calls & emails promptly. We are greatly pleased with her as far as her professionalism, courtesy and promptness throughout my H1B Renewal Process. We are very Thankful to Rajiv and his Staff.
