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.- S. V., Assistant Professor
Thank you to this team for working diligently and patiently with me to help build my case and get the EB1A petition approved.

顾客见证
I am thankful to Victoria Chen and her immigration team for making this happen. I got my I-140 approved in EB1A category. This group is highly professional and I am very satisfied with the services. The reply to all of my questions were prompt. The team is extremely meticulous with documentation and drafting of letters, especially the petition. I strongly recommend North American Immigration Law group for US immigration!!!!- P., Neuroradiologist and Research Scientist
The Chen Immigration Law group was recommended to me by a fellow postdoc at a networking event. He claimed that if they say that my credentials are good enough to file a case for a green card then it is almost certain success. He was absolutely right.- P. F., Post-doctoral Scientist
After evaluating my credentials we decided to apply under the EB2-NIW category. Overall, it was a pleasure working with them. All my questions were answered promptly and to the point. Although the communication was only through emails, it was very effective. They made very clear to me what documents are necessary and how to obtain them and they drafted amazing reference letters and the I-140 petition letter. The price was very reasonable (the best I could find) and they always keep their timeline.
I am really grateful for their service and I highly recommend them. Thank you so much!
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.- J. L., Postdoctoral Fellow
I decided to choose North America Immigration Law Group based on some positive feedback and experiences that some of my friends had with. Working with them was great.

My application was approved in less than 60 days- M. M., Postdoc
I highly recommend them to anyone who needs their service, specially for NIW category. I already have referred some of my friends to Chen Immigration Law Services and they are also very happy and satisfied with their service.
Words can not describe my level of satisfaction working with folks at WeGreened. They have a rigid systematic approach to submit cases to USCIS (i.e. EB2-NIW in my case).- T. J., Affiliate Faculty
