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

I'm very happy with all the work and advice Chen Immigration Team have put into my NIW application. The responses were always timely, the letters drafted were polite, well-structured and timely. When I got my RFE, I was worried, but with the help of the attorneys working with me, the answer to the RFE lead to approval.
Not only do the members of the team work extremely hard and with highest professionalism, they also show that they believe in their clients, are able to emphasize all the achievements better than I ever could, and they genuinely care.
Thank you so very much!
I cannot be happier with everything you've done for me!

- M, Postpoc

I had worked with Chen Immigration group for my O-1A visa first and then retained with them for my I-140 petition under EB1A category. Their services are rapid and prompt with an affordable fee structure. They also have very high success rate of approvals. They have taken utmost care on all the required documentation. They usually respond to my questions in 1 business day. I highly recommend Chen Immigration group for my fellow colleagues for their petitions under various categories.

- R. V., Chief Technology Officer

I had a great experience working with Chen Immigration Law Group. I applied for EB1A premium processing and the case was approved within 2 weeks without any RFE.
I was impressed with the quality of petition letter and the reference letters drafted by their team. Although my field is highly technical, the attorneys seemed highly knowledgeable and were able to present my research in a manner which was easy to understand, impressive and yet not 'over-selling'.
They went over my research/citations meticulously and were able to catch mistakes which honestly I would have missed if I was preparing my own case. They were also very prompt with replying to any questions I had during the process.
In short, I would strongly recommend them to all who want to get through the green card process without stress.

- P. J., Postdoctoral Researcher

I received my EB1 A I 140 approval notice a few days ago.

They are very thorough in evaluating your case , respond within 24 hours to every questions you post and work diligently in getting petition letter and LOS done in time . There is no doubt in my mind that Chen immigration are the best attorneys to represent your case.
I have recommended several of my friends and will continue to do so. Thank you so much!
