The efforts put forth by Chen Immigration and Attorneys has been instrumental in obtaining the approvals for my O1-A and EB-1B (I-140) petitions. The approvals came in 4 and 8 days respectively after request for premium processing. However, this did not happen overnight and neither did I want them to happen overnight. Although my credentials were in place for both the petitions, most of the time was spent on preparing the materials and revising them over and over again. I was very busy in my job and barely had time to go over revisions in a continuous basis. However, the team kept at it, always responding to my questions and carefully going over every single piece of text and supporting evidence. Being trained as a scientist during my PhD, I would say, it was more like writing an academic paper with collaborators - everybody invested time and energy into the process and in the end the paper got accepted. This is a win for us all!- P. D., Senior Research Scientist
It took around 5 months to prepare the materials mostly because of my intermittent involvements but it was worth the wait. That being said, the logical constructs and inferences laid down by my team of lawyers to construct the reasoning as to why I may be suitable candidate in the area of O1-A and EB-1B criteria is outstanding - there simply was not much room to refute the arguments. Very well done! I will always keep you in mind.

The folks at Chen Immigration know what they are doing and did a fantastic job. They are extremely knowledgeable and helped me throughout the application process. Their letters were of top quality and would recommend them any day for any immigration related matters. Kudos to North America Immigration Law Group's team. Keep up the good work!!!- A. S., Principal Consultant
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!<- M. W. M, Enterprise Applications Administrator and Developer
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.
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.- S. A., Postdoctoral Researcher
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.
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
One word to define Chen immigration: 'Professional'- D. T.
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.
