I'm so excited that my I-140 got approved within such a short time! I do think the North America Immigration Law Group did a great job. They are so patient to answer lots of my questions. The recommendation letters and petition letter are well prepared. That saved lots of my time! I will definitely recommend to my friends, as well as other people who prepare to apply for green card!- X. L., Postdoctoral Fellow
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.
I highly recommend them.
2 years ago when I googled saying 'Best immigration lawyer for NIW' - It showed up Chen immigration on top of the list at Yelp. I decided to work with Chen immigration firm and now I am highly satisfied with my decision.- M. S., Postdoctoral Research Associate
My EB2-NIW application has been approved after 13 months. Chen immigration helped me to submit this application. I am very much impressed the way they prepare my application for this category. They are very professional ! I have already recommended dozen of my friends to Chen immigration and will highly recommend to all those who are currently looking for immigration lawyer in USA.
I am Associate Professor in Mechanical Engineering. I would like to extend my deepest gratitude to Chen immigration group for their great help on my NIW-I-140 case preparation and filing. Undoubtedly without your help, it was not possible to get my application approved. Thank you for such an amazing support. Their professional guidance, patience, and prompt responses make the whole process efficient and successful. I highly recommend Chen immigration group!- A. A. D. S., Associate professor at Engineering
I greatly appreciate Chen Immigration Law team for all the help and support, and for their very professional service, from the beginning to the end of my I-140 approval!<- M. W. M, Enterprise Applications Administrator and Developer
My experience with them with filing my EB2-NIW petition steamily positive. They are professional, well-mannered, timely, and helped us steered through the complex petition process.
I talked with couple of others law firms but find out that Chen Immigration has refund policy, means that they do their homework according to your case before file the case. Which give me more confidence. At the end I figure out that the work very hard to prepare my case. I highly recommend to people if they want to apply for I-140.
I worked with this firm for my I-140 EB2-NIW application. They delivered everything as promised. Preparing documents for this application is a cumbersome work but WeGreened makes it really straightforward and simple. All I had to do was to write a research summary and contact my references for recommendation letters. Even for these steps they provided some samples and templates. Their messaging platform is great! Although I never talked to any of the attorneys on the phone, all my questions were responded within less than 24 hours on the messaging platform.- B. M., RF Computational Engineer
