Client Testimonials

My I-140 petition under NIW category got approved. I have a phd in mechanical engineering and was a postdoctoral fellow at the time of submitting my petition. I would like to thank Chen Immigration Team in drafting the petition and recommendation letters. I am impressed by their professionalism, their willingness to respond to any question in a timely manner and their dedication in emphasizing every aspect of my work and research. I would not be able to draft such an assuring petition letter myself. I am so grateful to have Chen Immigration Team as my attorney. I highly recommend Chen immigration law group. Thank you so much.

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

We just wanted to thank Chen Immigration for their help during this process. They were absolutely amazing. They responded to all our questions with such detail and were thorough in their examination of all our supporting documentation. They were quick with their responses and always stuck to the timeline. They provided us amazing templates for all out letters of recommendation and overall were exceptional. Highly competent and would strongly recommend to anybody looking for immigration assistance.

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 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 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.
