The folks at Chen Immigration know what they are doing and did a fantastic job. They are extremely knowledgeable and helped me throughout the application process. Their letters were of top quality and would recommend them any day for any immigration related matters. Kudos to North America Immigration Law Group's team. Keep up the good work!!!

- A. S., Principal Consultant

I would like to thank the Chen Immigration team for getting my I-140 (EB-1B) approved with no RFE. I choose premium processing and the case was approved in 13 days. The team is very professional and helpful in every step on your way to the approval. I had many questions from time to time during the preparation process and they were answered in a timely manner. I have also retained them for I-485 and hope that it will also be approved in a timely manner.

- A. K.

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.

The best thing to happen to me in my GC process was my friend's recommendation of NAILG. They have been impeccable when it comes to keeping their promised time. They have also been giving me appropriate advice at appropriate times and have prepared a 1i140 packet that I could not have done myself in 100 years. I can't thank them enough.

- K. K., Research Scientist

I applied for EB-2 trough North America Immigration Law Group. I got the I-140 approval in one month ! I would like to greatly appreciate for their professional jobs. According to my interaction with them in filling out the I-140 application during several months, I found them very trustful and expert. Therefore it is my pleasure to highly recommend this firm to persons who like to apply for EB-2 green card or related ones. In addition, the application fee is cheaper that other immigration attorneys. Thanks a lot
