Client Testimonials

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

This team lives up to your ideals about how an attorney should be: punctual, prepared, organized, and professional.
They filed a petition for I140 through NIW-EB2 on my behalf and I received an approval notice in less than 5 months. Chen Immigration team has made this process from the very beginning to the end very smooth.
I am glad to recommend them to anyone planning to file for an NIW.

- Y. N., Coastal Engineer

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).
No hitting around the bush during working with you. Straight forward and logical folks. They throw it into your face when you are wrong, accept it with big heart if they fail. Turn-back time to your questions is within 24 business hours with no doubt at every single step of the progress. Do not doubt for even a single second to choosing them, regardless of your geographical point.

- T. J., Affiliate Faculty

I highly recommend Chen Immigration Law Group. Through the I-140 application process and after, they took care of every steps in a very professional way. They answered my questions in a short period of time. They were great! I don't think we could have than it without them. Our I-140 got approved in 57 days. So Chen Immigration is the best!

- A. O., Postdoctoral Associate

My EB1A was approved four days after USCIS received my documents. I'm very impressed by the professionalism and enthusiasm of NAmILG during preparation and filing of my case. The prompt approval of my case wouldn't be possible without the expertise and hard working of the attorneys of NAmILG.
One of the advantages of NAmILG I want to point out is they drafted all of the required letters, which saved huge amount of time for me. I'll definitely recommend to my friends who are looking for immigration attorneys.

- T. W., Postdoc

After filing (PP), I have got an RFE and after 3 months, my I-140 was approved. I am really thankful to Chen Immigration Law firm and appreciate their efforts in working with me patiently in a precognitive manner. They have provided me with professional Reference Letters, Petition Letters, and Testimonials. They have always replied to my questions very promptly and efficiently. I came to know their service through a friend of mine and I am glad about it. I would definitely recommend people to use North America Immigration Law Group for their service regarding EB1A.
