Client Testimonial

My I-140 petition under NIW category got approved. I have a phd in mechanical engineering and was a postdoctoral fellow at the time of submitting my petition. I would like to thank Chen Immigration Team in drafting the petition and recommendation letters. I am impressed by their professionalism, their willingness to respond to any question in a timely manner and their dedication in emphasizing every aspect of my work and research. I would not be able to draft such an assuring petition letter myself. I am so grateful to have Chen Immigration Team as my attorney. I highly recommend Chen immigration law group. Thank you so much.

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. They are very supportive and professional and they are well familiar with the rules and process. Everything was delivered on-time exactly as they promised. My application was approved in less than 60 days
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.

Three of my friends who already got green card in EB1 category with the help of Chen immigration recommended me to contact this firm. They gave me free evaluation and approve and refund policy for my EB1B. I don’t know about other firm but I can say that I had a very good experience with Chen immigration. My attorney guided me on every single step and never got irritated even if asked same question several times. I got the answer of all my questions within 24 hours of time. As they promised, they wrote very strong letter of recommendation and drafted my petition within timeline. I was impressed the way they presented my case in the petition and as a results my case got approved in 7 days. I would strongly recommend Chen immigration to anyone trying to get green card under EB1 category. As I heard from my friends and I also experienced that they are the best with impressive team of attorneys. Thank you so much Chen immigration. It would not have been possible without your help. You are doing really good job. Keep it up !
Highly Recommended !!!!

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.

- A. K.

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

Thank You Chen Immigration and Attorneys for your tremendous effort on helping me approve my NIW EB-2 petition. They are very professional from start to end.

If anyone of you plan to file your NIWS, Chen Immigration and Attorneys are probably the best options out there.
