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

I have to say the team at Chen Immigration Law Associates are very professional and responsive. My I-140 NIW EB-2 was approved recently and I truly appreciate all the patience and efforts that their team did for my case. As a result of this satisfactory experience, I am planning to continue working with Chen Immigration group for my I-485 case. Before applying for NIW, I searched many other lawyers and this firm was the best among them. Good luck everyone!

- A. S., Teaching/Research Assistant

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!

- P. F., Post-doctoral Scientist

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

I am glad to know that my EB1 I-140 is approved. You made my dream come true. I am very thankful to North America Immigration Law Group. In addition to one's extraordinary credential, it is very important to have very good attorney for this success. Chen immigration attorneys are very brilliant and professional. They are very prompt in replying every query.
My several friends recommended Chen immigration and indeed they are great. I worked with Ms. Chen and Mr. Ingebritson. They have explained and simplified all process. Their wining strategy of selecting most useful credentials and presentation helped me in success of my case. I am completely satisfied with their service and highly recommending to everyone who is interested in employment-based green card application.
Thank you very much for all your help and advice during entire process of my application.

- P. N., Postdoctoral Fellow

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.

Success Story: EB1A Approved Despite RFE! Dual NIW + EB1A Victory for Indian Medical Director via Premium Processing

“It has been a pleasure working with Chen on my EB1A NIW journey. I heard about Chen years ago and hence had the confidence to go with them. I liked their meticulous attitude in preparing the case draft and collecting evidence. Chen has a ton of experience with EB1 and NIW categories. Chen has also been prompt in responding to my queries. I was told the officer who had issued my RFE had only a 30% approval rate. I was nervous due to the recent significant drop in the EB1A approval rate. However, Chen was a great help throughout the process, and I am satisfied with her service. I wish them all the best and endorse her for physicians willing to file an EB1A NIW petition.”
