I filed my I-140 (NIW) in May 2004 in CSC and got RFE letter in March 2005. Your firm gave me the best advices on how to respond. They gave me so much confidence and the advices were so essential. I got the approval eventually! To a large degree, the success of my NIW petition was because of high-quality professional services I received from the attorney and the assistants of the office. I really appreciate the help and patience throughout the entire process.
