顾客见证

I'm so excited that my I-140 got approved within such a short time! I do think the North America Immigration Law Group did a great job. They are so patient to answer lots of my questions. The recommendation letters and petition letter are well prepared. That saved lots of my time! I will definitely recommend to my friends, as well as other people who prepare to apply for green card!

- X. L., Postdoctoral Fellow

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

I have to say the team at Chen Immigration Law Associates are very professional and responsive. My I-140 NIW EB-2 was approved recently and I truly appreciate all the patience and efforts that their team did for my case. As a result of this satisfactory experience, I am planning to continue working with Chen Immigration group for my I-485 case. Before applying for NIW, I searched many other lawyers and this firm was the best among them. Good luck everyone!

- A. S., Teaching/Research Assistant

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

We just wanted to thank Chen Immigration for their help during this process. They were absolutely amazing. They responded to all our questions with such detail and were thorough in their examination of all our supporting documentation. They were quick with their responses and always stuck to the timeline. They provided us amazing templates for all out letters of recommendation and overall were exceptional. Highly competent and would strongly recommend to anybody looking for immigration assistance.

- G. B.

I would like to thank the Chen Immigration team for getting my I-140 (EB-1B) approved with no RFE. I choose premium processing and the case was approved in 13 days. The team is very professional and helpful in every step on your way to the approval. I had many questions from time to time during the preparation process and they were answered in a timely manner. I have also retained them for I-485 and hope that it will also be approved in a timely manner.
