Client Testimonials

I worked with this firm for my I-140 EB2-NIW application. They delivered everything as promised. Preparing documents for this application is a cumbersome work but WeGreened makes it really straightforward and simple. All I had to do was to write a research summary and contact my references for recommendation letters. Even for these steps they provided some samples and templates. Their messaging platform is great! Although I never talked to any of the attorneys on the phone, all my questions were responded within less than 24 hours on the messaging platform.

- B. M., RF Computational Engineer

Many thanks to Chen immigration & Attorneys for their great help, and I had a very good experience working with this professional attorney team, they prepared high quality recommendation letters and petition letters, provide guide in detail and response questions in time, I am lucky to have such a team to help me get the approval. I strongly recommended them to all who are seeking green card.

- Y. H., Postdoctoral Research Associate

Words can not describe my level of satisfaction working with folks at WeGreened. They have a rigid systematic approach to submit cases to USCIS (i.e. EB2-NIW in my case).
No hitting around the bush during working with you. Straight forward and logical folks. They throw it into your face when you are wrong, accept it with big heart if they fail. Turn-back time to your questions is within 24 business hours with no doubt at every single step of the progress. Do not doubt for even a single second to choosing them, regardless of your geographical point.

- T. J., Affiliate Faculty

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

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!<
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.

- M. W. M, Enterprise Applications Administrator and Developer

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

Success Stories: Customized NIW Petition Approved in 6 Months for Postdoctoral Researcher from Greece in the Field of Molecular Biology

I cannot thank enough NAmILG and Ms. Victoria Chen for their professional help in getting my I-140 NIW application approved. First, they reviewed my CV and gave me a realistic estimation of my case. They worked diligently with me from the time that I retained them until we filed the application. They walked me through the process step by step. It was a ton of paperwork but I am glad that I entrusted them with my case. You have to do your part of work, which is to provide them with the material that they need to build your case. This is not done overnight and it requires a lot of effort on your part. Nothing is done miraculously but NAmILG has the experience to put together a very compelling case. They replied promptly to all of questions and requests. I received approval notice for my I-140 NIW application after 6 months. I am retaining them for my I-485 application. I would definitely recommend them to all of my international colleagues and friends. In my opinion they are the gold standard in the immigration law business.
