顾客见证

The Chen Immigration Law group was recommended to me by a fellow postdoc at a networking event. He claimed that if they say that my credentials are good enough to file a case for a green card then it is almost certain success. He was absolutely right.
After evaluating my credentials we decided to apply under the EB2-NIW category. Overall, it was a pleasure working with them. All my questions were answered promptly and to the point. Although the communication was only through emails, it was very effective. They made very clear to me what documents are necessary and how to obtain them and they drafted amazing reference letters and the I-140 petition letter. The price was very reasonable (the best I could find) and they always keep their timeline.
I am really grateful for their service and I highly recommend them. Thank you so much!

- P. F., Post-doctoral Scientist

My EB1B I-140 got approved within 10 business days. I have worked with Chen Immigration Team from North America Immigration Law Group for 4 months before submitting my application. They were extremely thorough, meticulous and prompt with their service. They drafted all the necessary letters (employment verification, recommendation letters and petition letter) within the agreed timeline. They helped me to choose potential recommenders and were always quick to answer any of my questions. They are very professional and definitely know what they are doing. I will definitely recommend Chen Immigration Team to anyone who is planning to apply for Permanent Residency Status in USA.

- B., Scientist

I am thankful to Victoria Chen and her immigration team for making this happen. I got my I-140 approved in EB1A category. This group is highly professional and I am very satisfied with the services. The reply to all of my questions were prompt. The team is extremely meticulous with documentation and drafting of letters, especially the petition. I strongly recommend North American Immigration Law group for US immigration!!!!

- P., Neuroradiologist and Research Scientist

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 !!!!

The folks at Chen Immigration know what they are doing and did a fantastic job. They are extremely knowledgeable and helped me throughout the application process. Their letters were of top quality and would recommend them any day for any immigration related matters. Kudos to North America Immigration Law Group's team. Keep up the good work!!!

- A. S., Principal Consultant

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
