Client Testimonials

Thank you to the North American Immigration Law Group/Chen Immigration and Attorneys for their unwavering support and help in helping my secure my I-140 approval under EB1A and also under NIW. Their service was professional and timely. They answered my million and one questions with patience and worked with me on every stage of the process. They helped draft the letters and were open to edits and comments from me. What I also liked was that they were open to receiving suggestions from me to help strengthen my case especially when we were responding to our RFE.
Thank you to this team for working diligently and patiently with me to help build my case and get the EB1A petition approved.
I highly recommend them.

- S. V., Assistant Professor

It has been a pleasure working with the Wegreened Team. I always received prompt, courteous and professional responses from them throughout the EB1A filing process. They guided me in developing the material for the reference letters, drafted the letters in a timely manner and prepared a strong case which eventually lead to success. I am really grateful to them for all their help.

- V. J., Senior Engineer

It was a long and tough journey to prepare the EB-1A I-140. However, with the professional assistance and prompt feedback from the NAIL firm, this process has become much easier. They always stick to the deadlines that have been promised (preparing reference letter in 10 days, petition letter in 10 days). Thank you Chen associates for your enormous help, which helped me get my case approved one day after USCIS received my Form I-140. I will absolutely recommend you to every of my friends who will be applying for the green card in the future.
