Never use Law offices of Aruna Venkidu for your Immigration purposes. She handled my H1B extension cases for 8 years, they were simple and easy, just fill in the paperwork and send it in and charge me the fee. Then when time came to file my permanent residency and some questions were raised during approval, she had no idea to handle the case. She is inexperienced in handling complex Green Card situations especially I140s. Overlooks things. Because of her negligence and oversight I lost my case. Now I have to go back after being a good citizen and working hard in US for over 10 years. So find someone who has better insight and ask questions about their experience in handling RFEs.
