Client Testimonials

I heard about this law firm from one of my friends who had high recommendation. Before approaching Chen Immigration Law Associates, I had personally talked to an immigration lawyer whose fee was expensive and the lawyer did not seem much positive regarding my EB2-NIW case. When I first contacted Chen Immigration Law Associates for free EB2-NIW evaluation and heard that my case is eligible for approval or refund, it energized me and made me believe that my case is strong enough too. Though communication was only through email, it was easy and reliable. The timeline set in the contract is always fulfilled. I am really happy that I chose this law firm and I highly recommend it to anyone seeking immigration advice and services. Once again, I am very thankful to the team of Chen Immigration Law Associates for all their effort in making my petition a success.

- O. P.

I greatly appreciate Chen Immigration Law team for all the help and support, and for their very professional service, from the beginning to the end of my I-140 approval!<
My experience with them with filing my EB2-NIW petition steamily positive. They are professional, well-mannered, timely, and helped us steered through the complex petition process.
I talked with couple of others law firms but find out that Chen Immigration has refund policy, means that they do their homework according to your case before file the case. Which give me more confidence. At the end I figure out that the work very hard to prepare my case. I highly recommend to people if they want to apply for I-140.

- M. W. M, Enterprise Applications Administrator and Developer

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

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

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 !!!!
