I highly appreciate the outstanding work and help provided by North America Immigration Law group to me during my I-140 petition. They have very good understanding of the case and even easily understood my research and full profile to make the petition. There response before committed time is really appreciable. I found that the case taken by them is a big assurance that it is going to be approved. My EB1A- I-140 got approved very quickly even the day after the premium processing application was received without any RFE or difficulty.
I highly recommend Chen Immigration Team for green card petitions. Thanks a lot for their big help.

- S. S., Group Scientist

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!

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.

I would like to thank the Chen Immigration team for getting my I-140 (EB-1B) approved with no RFE. I choose premium processing and the case was approved in 13 days. The team is very professional and helpful in every step on your way to the approval. I had many questions from time to time during the preparation process and they were answered in a timely manner. I have also retained them for I-485 and hope that it will also be approved in a timely manner.
