Client Testimonials

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

I will definitely recommend North America Immigration Law Group to all my friends who is seeking for immigration services. I am very, very impressed by their excellent service.

Their service and attitude towards every case define their high reputation.

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.

It was a long and tough journey to prepare the EB-1A I-140. However, with the professional assistance and prompt feedback from the NAIL firm, this process has become much easier. They always stick to the deadlines that have been promised (preparing reference letter in 10 days, petition letter in 10 days). Thank you Chen associates for your enormous help, which helped me get my case approved one day after USCIS received my Form I-140. I will absolutely recommend you to every of my friends who will be applying for the green card in the future.

- J. 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 heard about this law firm from one of my friends who had high recommendation. Before approaching Chen Immigration Law Associates, I had personally talked to an immigration lawyer whose fee was expensive and the lawyer did not seem much positive regarding my EB2-NIW case. When I first contacted Chen Immigration Law Associates for free EB2-NIW evaluation and heard that my case is eligible for approval or refund, it energized me and made me believe that my case is strong enough too. Though communication was only through email, it was easy and reliable. The timeline set in the contract is always fulfilled. I am really happy that I chose this law firm and I highly recommend it to anyone seeking immigration advice and services. Once again, I am very thankful to the team of Chen Immigration Law Associates for all their effort in making my petition a success.
