顾客见证

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.

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.

- M. M., Postdoc

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

When i looked at all the reviews for the immigration firm, Chen immigration caught my attention for two reason, effective clear communication and their experience to approve otherwise difficult cases. After the initial free evaluation by their experienced attorneys they presented me with step by step instructions and options. I took a week to understand and signed the contract with them. My only concern at that time was not seeing the firm in person as everything is online, However that concern was gone as i saw their work ethics. They are super professional and respect the timelines and deadlines. they meticulously prepare all the documents, which is really important for such cases. I had a wonderful experience with them. I had already recommended two of my friends to hire them. I hired them for both I-140 and I-485. My I-140 was filed with PP and I received the approval in 8 days.

- L. S., Postdoctoral Fellow

I cannot describe how excited I was when I got to know that my I-140 EB1A application has been approved. This simply could not be true if without the professional help from the North America Immigration Law Group. I don't think that my background conditions were safe for this application. But I knew that their preparation strategy made my case pretty strong. Although the application was long and challenging, it was very nice to work with their team during the whole process period. They impressed me with excellence, professionalism, and highly responsiveness. I do believe that their service is the best one in the immigration business.
Thank you so much for your effort to help me get through the EB1A application. I have recommended and will be happy to continue recommending your professional team to other people who really want to be greened.

- K. J., Electrical Engineer at New York State

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!
