Client Testimonial

Many thanks to Chen immigration & Attorneys for their great help, and I had a very good experience working with this professional attorney team, they prepared high quality recommendation letters and petition letters, provide guide in detail and response questions in time, I am lucky to have such a team to help me get the approval. I strongly recommended them to all who are seeking green card.

- Y. H., Postdoctoral Research Associate

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 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 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

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 !!!!

- Dr. S. R., Assistant Professor

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.
