Very dependable and very friendly to work with. They were very prompt in answering every of my questions; and trust me they have been very kind to have responded to silliest of my doubts and concerns. I strongly recommend them to all my friends.

Many thanks to NAmILG/Chen Immigration for the quality and efficiency of their services. They have always replied very fast to any of my requests or questions. They have provided me with very clear answers and guidelines to navigate the I-140 application process. Their preparation of the file and their drafting of letters were thoroughly thought out and meticulous. I consider they have played a key role in the success of my I-140 application.
I would highly recommend Chen Immigration for their professionalism, honesty, and straightforwardness.

- P. A. M., Postdoctoral fellow

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!

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 !
