I applied for EB-2 trough North America Immigration Law Group. I got the I-140 approval in one month ! I would like to greatly appreciate for their professional jobs. According to my interaction with them in filling out the I-140 application during several months, I found them very trustful and expert. Therefore it is my pleasure to highly recommend this firm to persons who like to apply for EB-2 green card or related ones. In addition, the application fee is cheaper that other immigration attorneys. Thanks a lot

- R. N., Independent Research Scientist

I would like to thank Chen Associates for their great help to get the approval for my I-140 petition. I had very pleasant experince working with them and I am highly satisfied with their work.They are very professional and have many experiences on preparing the documents for the immigrant petition. They know about the strength of your case and I receive the I-140 approval notice (NIW) just after 3 months. I also retained them for the I-485 service. I highly recommend your firm to scientists and research scholars. This is one of the best choices in my life.

- N. F., PhD

I am Associate Professor in Mechanical Engineering. I would like to extend my deepest gratitude to Chen immigration group for their great help on my NIW-I-140 case preparation and filing. Undoubtedly without your help, it was not possible to get my application approved. Thank you for such an amazing support. Their professional guidance, patience, and prompt responses make the whole process efficient and successful. I highly recommend Chen immigration group!

- A. A. D. S., Associate professor at Engineering

The efforts put forth by Chen Immigration and Attorneys has been instrumental in obtaining the approvals for my O1-A and EB-1B (I-140) petitions. The approvals came in 4 and 8 days respectively after request for premium processing. However, this did not happen overnight and neither did I want them to happen overnight. Although my credentials were in place for both the petitions, most of the time was spent on preparing the materials and revising them over and over again. I was very busy in my job and barely had time to go over revisions in a continuous basis. However, the team kept at it, always responding to my questions and carefully going over every single piece of text and supporting evidence. Being trained as a scientist during my PhD, I would say, it was more like writing an academic paper with collaborators - everybody invested time and energy into the process and in the end the paper got accepted. This is a win for us all!
It took around 5 months to prepare the materials mostly because of my intermittent involvements but it was worth the wait. That being said, the logical constructs and inferences laid down by my team of lawyers to construct the reasoning as to why I may be suitable candidate in the area of O1-A and EB-1B criteria is outstanding - there simply was not much room to refute the arguments. Very well done! I will always keep you in mind.

- P. D., Senior Research Scientist

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'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!
