- A. C., Postdoc

The best thing to happen to me in my GC process was my friend's recommendation of NAILG. They have been impeccable when it comes to keeping their promised time. They have also been giving me appropriate advice at appropriate times and have prepared a 1i140 packet that I could not have done myself in 100 years. I can't thank them enough.

- K. K., 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

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

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
