Client Testimonials

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!
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.

- P. D., Senior Research Scientist

WeGreened has been a pleasure to work with. They were so thorough with everything. With their very knowledgeable and able support and timely help in every respect I could finally get my I-140 approved in EB-1A category.
I would therefore highly recommend them to all who wants to file a permanent residency.

- R. C., Senior Development Scientist

I am thankful to Victoria Chen and her immigration team for making this happen. I got my I-140 approved in EB1A category. This group is highly professional and I am very satisfied with the services. The reply to all of my questions were prompt. The team is extremely meticulous with documentation and drafting of letters, especially the petition. I strongly recommend North American Immigration Law group for US immigration!!!!

- P., Neuroradiologist and Research Scientist

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 had a great experience working with Chen Immigration Law Group. I applied for EB1A premium processing and the case was approved within 2 weeks without any RFE.
I was impressed with the quality of petition letter and the reference letters drafted by their team. Although my field is highly technical, the attorneys seemed highly knowledgeable and were able to present my research in a manner which was easy to understand, impressive and yet not 'over-selling'.
They went over my research/citations meticulously and were able to catch mistakes which honestly I would have missed if I was preparing my own case. They were also very prompt with replying to any questions I had during the process.
In short, I would strongly recommend them to all who want to get through the green card process without stress.

- P. J., Postdoctoral Researcher

I received my EB1 A I 140 approval notice a few days ago.
Chen Immigration made this possible. it would have been very difficult to pull this through without their help!
They are very thorough in evaluating your case , respond within 24 hours to every questions you post and work diligently in getting petition letter and LOS done in time . There is no doubt in my mind that Chen immigration are the best attorneys to represent your case.
I have recommended several of my friends and will continue to do so. Thank you so much!
