Chen Immigration Attorneys were vital towards my successful approval of I-140. From the beginning to the end every step of the way they did an amazing job in reviewing my documents, responding to my questions with helpful, detailed, and practical solutions, and also being professional about everything. In particular, the letters of recommendations they prepared were absolutely amazing. Most of the letters required little to no editing and my recommenders were happy with them. I feel that their quality of work, their knowledge of the process, and their detail towards everything reduced my stress significantly and helped me obtain a successful approval. I recommend their team to everyone looking to work on their EB-2 NIW application as they will be thorough and detailed with everything. In addition, I was able to tell that their vast amount of experience with these types of applications was an important part of successfully submitting all documentation. Thank you again Chen Immigration Attorneys!
