Client Testimonials

The best thing to happen to me in my GC process was my friend's recommendation of NAILG. They have been impeccable when it comes to keeping their promised time. They have also been giving me appropriate advice at appropriate times and have prepared a 1i140 packet that I could not have done myself in 100 years. I can't thank them enough.

- K. K., 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 !!!!

First of all, I want to thank the immigration team for their timely and excellent services. They were absolute joy to work with and the team was thorough, experienced and well placed to provide me excellent reviews, advice throughout my EB2-NIW application process. I have already recommended a few of my friends who already echo my sentiments and will continue to refer Chen Immigration services to anyone who seek my advice.

A real pleasure to work with Chen Immigration. I'm very satisfied with the process and, of course, with the result!
It was a persistent, systematic everyday job of their team for several months, tons of e-mails, all replied professionally. No need for a single phone call! No nerves, no hash, no mess, just persistent professional work that resulted in my approval.
Yes they ask for many supporting documents and evidence but the result is a very strong case approved without any RFE. That's extremely important to save time and nerves.

- A. B.

I had worked with Chen Immigration group for my O-1A visa first and then retained with them for my I-140 petition under EB1A category. Their services are rapid and prompt with an affordable fee structure. They also have very high success rate of approvals. They have taken utmost care on all the required documentation. They usually respond to my questions in 1 business day. I highly recommend Chen Immigration group for my fellow colleagues for their petitions under various categories.

- R. V., Chief Technology Officer

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.
