Client Testimonials

My EB1A was approved four days after USCIS received my documents. I'm very impressed by the professionalism and enthusiasm of NAmILG during preparation and filing of my case. The prompt approval of my case wouldn't be possible without the expertise and hard working of the attorneys of NAmILG.
One of the advantages of NAmILG I want to point out is they drafted all of the required letters, which saved huge amount of time for me. I'll definitely recommend to my friends who are looking for immigration attorneys.

- T. W., Postdoc

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.

- M. W. M, Enterprise Applications Administrator and Developer

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

The Chen Immigration Law group was recommended to me by a fellow postdoc at a networking event. He claimed that if they say that my credentials are good enough to file a case for a green card then it is almost certain success. He was absolutely right.
After evaluating my credentials we decided to apply under the EB2-NIW category. Overall, it was a pleasure working with them. All my questions were answered promptly and to the point. Although the communication was only through emails, it was very effective. They made very clear to me what documents are necessary and how to obtain them and they drafted amazing reference letters and the I-140 petition letter. The price was very reasonable (the best I could find) and they always keep their timeline.
I am really grateful for their service and I highly recommend them. Thank you so much!

- P. F., Post-doctoral Scientist

I'm so excited that my I-140 got approved within such a short time! I do think the North America Immigration Law Group did a great job. They are so patient to answer lots of my questions. The recommendation letters and petition letter are well prepared. That saved lots of my time! I will definitely recommend to my friends, as well as other people who prepare to apply for green card!

- X. L., Postdoctoral Fellow

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.
