Client Testimonials

2 years ago when I googled saying 'Best immigration lawyer for NIW' - It showed up Chen immigration on top of the list at Yelp. I decided to work with Chen immigration firm and now I am highly satisfied with my decision.
My EB2-NIW application has been approved after 13 months. Chen immigration helped me to submit this application. I am very much impressed the way they prepare my application for this category. They are very professional ! I have already recommended dozen of my friends to Chen immigration and will highly recommend to all those who are currently looking for immigration lawyer in USA.

- M. S., Postdoctoral Research Associate

The fact I like most about the Chen Immigration and Attorneys is their communication systems and responses. Throughout the whole application process until approval, I had lots of questions in different phases regarding case file preparation, EAD cards, travel with AP, service request etc. What I needed to do was to leave a message in the case management system and got detailed and satisfactory responses in a timely manner.
Their services ranging from the free evaluation at the first day to case preparation and drafting recommendation and petition letters have exhibited high professionalism and standard. I would suggest anyone to retain them for his/her I140 and I485 case preparation.

- S. A., Postdoctoral Researcher

It was a long and tough journey to prepare the EB-1A I-140. However, with the professional assistance and prompt feedback from the NAIL firm, this process has become much easier. They always stick to the deadlines that have been promised (preparing reference letter in 10 days, petition letter in 10 days). Thank you Chen associates for your enormous help, which helped me get my case approved one day after USCIS received my Form I-140. I will absolutely recommend you to every of my friends who will be applying for the green card in the future.

- J. L., Postdoctoral Fellow

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

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

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.

Success Stories: Customized NIW Petition Approved in 6 Months for Postdoctoral Researcher from Greece in the Field of Molecular Biology

I cannot thank enough NAmILG and Ms. Victoria Chen for their professional help in getting my I-140 NIW application approved. First, they reviewed my CV and gave me a realistic estimation of my case. They worked diligently with me from the time that I retained them until we filed the application. They walked me through the process step by step. It was a ton of paperwork but I am glad that I entrusted them with my case. You have to do your part of work, which is to provide them with the material that they need to build your case. This is not done overnight and it requires a lot of effort on your part. Nothing is done miraculously but NAmILG has the experience to put together a very compelling case. They replied promptly to all of questions and requests. I received approval notice for my I-140 NIW application after 6 months. I am retaining them for my I-485 application. I would definitely recommend them to all of my international colleagues and friends. In my opinion they are the gold standard in the immigration law business.
