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.

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.

- M. S., Postdoctoral Research Associate

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

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

Many thanks to NAmILG/Chen Immigration for the quality and efficiency of their services. They have always replied very fast to any of my requests or questions. They have provided me with very clear answers and guidelines to navigate the I-140 application process. Their preparation of the file and their drafting of letters were thoroughly thought out and meticulous. I consider they have played a key role in the success of my I-140 application.
I would highly recommend Chen Immigration for their professionalism, honesty, and straightforwardness.

- P. A. M., Postdoctoral fellow

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 greatly appreciate Chen Immigration Law team for all the help and support, and for their very professional service, from the beginning to the end of my I-140 approval!<
My experience with them with filing my EB2-NIW petition steamily positive. They are professional, well-mannered, timely, and helped us steered through the complex petition process.
I talked with couple of others law firms but find out that Chen Immigration has refund policy, means that they do their homework according to your case before file the case. Which give me more confidence. At the end I figure out that the work very hard to prepare my case. I highly recommend to people if they want to apply for I-140.
