顾客见证

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 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

When i looked at all the reviews for the immigration firm, Chen immigration caught my attention for two reason, effective clear communication and their experience to approve otherwise difficult cases. After the initial free evaluation by their experienced attorneys they presented me with step by step instructions and options. I took a week to understand and signed the contract with them. My only concern at that time was not seeing the firm in person as everything is online, However that concern was gone as i saw their work ethics. They are super professional and respect the timelines and deadlines. they meticulously prepare all the documents, which is really important for such cases. I had a wonderful experience with them. I had already recommended two of my friends to hire them. I hired them for both I-140 and I-485. My I-140 was filed with PP and I received the approval in 8 days.

- L. S., Postdoctoral Fellow

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 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

2 years ago when I googled saying 'Best immigration lawyer for NIW' - It showed up Chen immigration on top of the list at Yelp. I decided to work with Chen immigration firm and now I am highly satisfied with my decision.
My EB2-NIW application has been approved after 13 months. Chen immigration helped me to submit this application. I am very much impressed the way they prepare my application for this category. They are very professional ! I have already recommended dozen of my friends to Chen immigration and will highly recommend to all those who are currently looking for immigration lawyer in USA.
