顾客见证

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.

- V. J., Senior Engineer

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

It was an incredible experience working with Chen lawyers. I got my EB1A approved in 10 days. They were so perfect in their work and and took care of every little detail necessary. 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. Needless to mention, I am going to work with them for I-485 as well.

- T. 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 !!!!

- 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.

- J. L., Postdoctoral Fellow

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.
