Client Testimonial

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

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

I would like to thank Chen Associates for their great help to get the approval for my I-140 petition. I had very pleasant experince working with them and I am highly satisfied with their work.They are very professional and have many experiences on preparing the documents for the immigrant petition. They know about the strength of your case and I receive the I-140 approval notice (NIW) just after 3 months. I also retained them for the I-485 service. I highly recommend your firm to scientists and research scholars. This is one of the best choices in my life.

- N. F., PhD

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

When i looked at all the reviews for the immigration firm, Chen immigration caught my attention for two reason, effective clear communication and their experience to approve otherwise difficult cases. After the initial free evaluation by their experienced attorneys they presented me with step by step instructions and options. I took a week to understand and signed the contract with them. My only concern at that time was not seeing the firm in person as everything is online, However that concern was gone as i saw their work ethics. They are super professional and respect the timelines and deadlines. they meticulously prepare all the documents, which is really important for such cases. I had a wonderful experience with them. I had already recommended two of my friends to hire them. I hired them for both I-140 and I-485. My I-140 was filed with PP and I received the approval in 8 days.

- L. S., Postdoctoral Fellow

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.
