顾客见证
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.
I cannot describe how excited I was when I got to know that my I-140 EB1A application has been approved. This simply could not be true if without the professional help from the North America Immigration Law Group. I don't think that my background conditions were safe for this application. But I knew that their preparation strategy made my case pretty strong. Although the application was long and challenging, it was very nice to work with their team during the whole process period. They impressed me with excellence, professionalism, and highly responsiveness. I do believe that their service is the best one in the immigration business.- K. J., Electrical Engineer at New York State
Thank you so much for your effort to help me get through the EB1A application. I have recommended and will be happy to continue recommending your professional team to other people who really want to be greened.
I'm very happy with all the work and advice Chen Immigration Team have put into my NIW application. The responses were always timely, the letters drafted were polite, well-structured and timely. When I got my RFE, I was worried, but with the help of the attorneys working with me, the answer to the RFE lead to approval.- M, Postpoc
Not only do the members of the team work extremely hard and with highest professionalism, they also show that they believe in their clients, are able to emphasize all the achievements better than I ever could, and they genuinely care.
Thank you so very much!
I cannot be happier with everything you've done for me!
I would like to thank Chen Associates for their great help to get the approval for my I-140 petition. I had very pleasant experince working with them and I am highly satisfied with their work.They are very professional and have many experiences on preparing the documents for the immigrant petition. They know about the strength of your case and I receive the I-140 approval notice (NIW) just after 3 months. I also retained them for the I-485 service. I highly recommend your firm to scientists and research scholars. This is one of the best choices in my life.- N. F., PhD
Thank you to the North American Immigration Law Group/Chen Immigration and Attorneys for their unwavering support and help in helping my secure my I-140 approval under EB1A and also under NIW. Their service was professional and timely. They answered my million and one questions with patience and worked with me on every stage of the process. They helped draft the letters and were open to edits and comments from me. What I also liked was that they were open to receiving suggestions from me to help strengthen my case especially when we were responding to our RFE.- S. V., Assistant Professor
