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.

Thank You Chen Immigration and Attorneys for your tremendous effort on helping me approve my NIW EB-2 petition. They are very professional from start to end. All the questions asked were answered in a professional manner in timely basis. I really appreciate all your work and suggestion during the process. If anyone of you plan to file your NIWS, Chen Immigration and Attorneys are probably the best options out there.

- M. K., Geophysicist

I'd like to thank Chen Immigration and attorneys for the great job they did on my I-140 application for NIW. They put together a compelling petition letter with appropriate exhibitions which resulted in my I-140 approval only in 72 days at Nebraska Service Center (the average wait time at this center is more than 10 months now). The team at this firm are experts and experienced. They meticulously prepare all the required documents and effectively communicate with the client. They deliver on time & with the highest quality. I have recommended them to my friends who would like to apply for NIW or EB1A. Chen group knows what they are doing and they are the best, go with them!

- H. C., Postdoctoral Scholar

My I-140 (NIW) was approved this week!
I was fortunate to come across Chen immigration when I started looking into my options for green card. I quickly realized they are extremely professional and would handle my case at a personal level. Indeed, over the last 1 year they have performed beyond my expectations.
Chen immigration team gave me a free evaluation after assessing my portfolio. Their timing for my case has been impeccable at every step. The lawyers have worked with me as a team. Communication with the whole firm has just been outstanding. I would recommend Chen Immigration extremely highly to all my friends and anyone who is in my shoes and looking into the process for Green card.

- M. R., Physician

I am thankful to Victoria Chen and her immigration team for making this happen. I got my I-140 approved in EB1A category. This group is highly professional and I am very satisfied with the services. The reply to all of my questions were prompt. The team is extremely meticulous with documentation and drafting of letters, especially the petition. I strongly recommend North American Immigration Law group for US immigration!!!!

- P., Neuroradiologist and Research Scientist

The fact I like most about the Chen Immigration and Attorneys is their communication systems and responses. Throughout the whole application process until approval, I had lots of questions in different phases regarding case file preparation, EAD cards, travel with AP, service request etc. What I needed to do was to leave a message in the case management system and got detailed and satisfactory responses in a timely manner.
Their services ranging from the free evaluation at the first day to case preparation and drafting recommendation and petition letters have exhibited high professionalism and standard. I would suggest anyone to retain them for his/her I140 and I485 case preparation.

- S. A., Postdoctoral Researcher
