Client Testimonials

I highly appreciate the outstanding work and help provided by North America Immigration Law group to me during my I-140 petition. They have very good understanding of the case and even easily understood my research and full profile to make the petition. There response before committed time is really appreciable. I found that the case taken by them is a big assurance that it is going to be approved. My EB1A- I-140 got approved very quickly even the day after the premium processing application was received without any RFE or difficulty.
I highly recommend Chen Immigration Team for green card petitions. Thanks a lot for their big help.

- S. S., Group Scientist

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

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 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

- R. N., Independent Research 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

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!
