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.- T. W., Postdoc
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.

The efforts put forth by Chen Immigration and Attorneys has been instrumental in obtaining the approvals for my O1-A and EB-1B (I-140) petitions. The approvals came in 4 and 8 days respectively after request for premium processing. However, this did not happen overnight and neither did I want them to happen overnight. Although my credentials were in place for both the petitions, most of the time was spent on preparing the materials and revising them over and over again. I was very busy in my job and barely had time to go over revisions in a continuous basis. However, the team kept at it, always responding to my questions and carefully going over every single piece of text and supporting evidence. Being trained as a scientist during my PhD, I would say, it was more like writing an academic paper with collaborators - everybody invested time and energy into the process and in the end the paper got accepted. This is a win for us all!- P. D., Senior Research Scientist
It took around 5 months to prepare the materials mostly because of my intermittent involvements but it was worth the wait. That being said, the logical constructs and inferences laid down by my team of lawyers to construct the reasoning as to why I may be suitable candidate in the area of O1-A and EB-1B criteria is outstanding - there simply was not much room to refute the arguments. Very well done! I will always keep you in mind.
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.- P. A. M., Postdoctoral fellow
I would highly recommend Chen Immigration for their professionalism, honesty, and straightforwardness.
I am glad to know that my EB1 I-140 is approved. You made my dream come true. I am very thankful to North America Immigration Law Group. In addition to one's extraordinary credential, it is very important to have very good attorney for this success. Chen immigration attorneys are very brilliant and professional. They are very prompt in replying every query.- P. N., Postdoctoral Fellow
My several friends recommended Chen immigration and indeed they are great. I worked with Ms. Chen and Mr. Ingebritson. They have explained and simplified all process. Their wining strategy of selecting most useful credentials and presentation helped me in success of my case. I am completely satisfied with their service and highly recommending to everyone who is interested in employment-based green card application.
Thank you very much for all your help and advice during entire process of my application.
