顾客见证

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

It is with great pleasure that I here come to express my highest gratitude and respect for North America Immigration Law Group. Victoria Chen and her incredible competent and professional Team of Attorneys are highly recommended by me. They diligently worked on my application and provided me with the best word of advice and expertise regarding my I-140 case. My process was approved within the standard and current processing time of four months. I am now, undoubtedly working with them again to apply for the I-485. I would recommend one and only Law Immigration Group, and that is Chen Immigration & Attorneys. This Team is stupendous.

- L. O., Senior Applications Engineer

My I-140 petition under NIW category got approved. I have a phd in mechanical engineering and was a postdoctoral fellow at the time of submitting my petition. I would like to thank Chen Immigration Team in drafting the petition and recommendation letters. I am impressed by their professionalism, their willingness to respond to any question in a timely manner and their dedication in emphasizing every aspect of my work and research. I would not be able to draft such an assuring petition letter myself. I am so grateful to have Chen Immigration Team as my attorney. I highly recommend Chen immigration law group. 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 !
Highly Recommended !!!!

- Dr. S. R., Assistant Professor

It has been a pleasure working with the Wegreened Team. I always received prompt, courteous and professional responses from them throughout the EB1A filing process. They guided me in developing the material for the reference letters, drafted the letters in a timely manner and prepared a strong case which eventually lead to success. I am really grateful to them for all their help.

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.
