顧客見證

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 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.
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.

- P. N., Postdoctoral Fellow

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!
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.

- P. D., Senior Research Scientist

I'm very happy with all the work and advice Chen Immigration Team have put into my NIW application. The responses were always timely, the letters drafted were polite, well-structured and timely. When I got my RFE, I was worried, but with the help of the attorneys working with me, the answer to the RFE lead to approval.
Not only do the members of the team work extremely hard and with highest professionalism, they also show that they believe in their clients, are able to emphasize all the achievements better than I ever could, and they genuinely care.
Thank you so very much!
I cannot be happier with everything you've done for me!

- M, Postpoc

I have to say the team at Chen Immigration Law Associates are very professional and responsive. My I-140 NIW EB-2 was approved recently and I truly appreciate all the patience and efforts that their team did for my case. As a result of this satisfactory experience, I am planning to continue working with Chen Immigration group for my I-485 case. Before applying for NIW, I searched many other lawyers and this firm was the best among them. Good luck everyone!
