顾客见证

My EB1B I-140 got approved within 10 business days. I have worked with Chen Immigration Team from North America Immigration Law Group for 4 months before submitting my application. They were extremely thorough, meticulous and prompt with their service. They drafted all the necessary letters (employment verification, recommendation letters and petition letter) within the agreed timeline. They helped me to choose potential recommenders and were always quick to answer any of my questions. They are very professional and definitely know what they are doing. I will definitely recommend Chen Immigration Team to anyone who is planning to apply for Permanent Residency Status in USA.

- B., Scientist

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

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

It was a privilege to work with Chen immigration attorneys during my NIW I-140 application. They were really professional and kept the deadlines depicted by the client-attorney agreement. They will answer your questions within a day with the maximum clarity. I would definitely recommend them to anyone looking to apply for a NIW green card. Thanks once again and keep up the good work.

- I. S., Research Scientist

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. The entire process is very professional and they have been responsive and responsible. They will do their best in every little detail to make you case stronger. Their service and attitude towards every case define their high reputation.

- B. H., Postdoctoral Research Fellow

I'm very happy with all the work and advice Chen Immigration Team have put into my NIW application. The responses were always timely, the letters drafted were polite, well-structured and timely. When I got my RFE, I was worried, but with the help of the attorneys working with me, the answer to the RFE lead to approval.
Not only do the members of the team work extremely hard and with highest professionalism, they also show that they believe in their clients, are able to emphasize all the achievements better than I ever could, and they genuinely care.
Thank you so very much!
I cannot be happier with everything you've done for me!
