顧客見證

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

A real pleasure to work with Chen Immigration. I'm very satisfied with the process and, of course, with the result!
It was a persistent, systematic everyday job of their team for several months, tons of e-mails, all replied professionally. No need for a single phone call! No nerves, no hash, no mess, just persistent professional work that resulted in my approval.
Yes they ask for many supporting documents and evidence but the result is a very strong case approved without any RFE. That's extremely important to save time and nerves.

- A. B.

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

One word to define Chen immigration: 'Professional'

First of all, I want to thank the immigration team for their timely and excellent services. They were absolute joy to work with and the team was thorough, experienced and well placed to provide me excellent reviews, advice throughout my EB2-NIW application process. I have already recommended a few of my friends who already echo my sentiments and will continue to refer Chen Immigration services to anyone who seek my advice.

- D. T.

My I-140 petition under NIW category got approved. I have a phd in mechanical engineering and was a postdoctoral fellow at the time of submitting my petition. I would like to thank Chen Immigration Team in drafting the petition and recommendation letters. I am impressed by their professionalism, their willingness to respond to any question in a timely manner and their dedication in emphasizing every aspect of my work and research. I would not be able to draft such an assuring petition letter myself. I am so grateful to have Chen Immigration Team as my attorney. I highly recommend Chen immigration law group. Thank you so much.

- V. V.

I had worked with Chen Immigration group for my O-1A visa first and then retained with them for my I-140 petition under EB1A category. Their services are rapid and prompt with an affordable fee structure. They also have very high success rate of approvals. They have taken utmost care on all the required documentation. They usually respond to my questions in 1 business day. I highly recommend Chen Immigration group for my fellow colleagues for their petitions under various categories.
