Client Testimonials

I had a great experience working with Chen Immigration Law Group. I applied for EB1A premium processing and the case was approved within 2 weeks without any RFE.
I was impressed with the quality of petition letter and the reference letters drafted by their team. Although my field is highly technical, the attorneys seemed highly knowledgeable and were able to present my research in a manner which was easy to understand, impressive and yet not 'over-selling'.
They went over my research/citations meticulously and were able to catch mistakes which honestly I would have missed if I was preparing my own case. They were also very prompt with replying to any questions I had during the process.
In short, I would strongly recommend them to all who want to get through the green card process without stress.

- P. J., Postdoctoral Researcher

I highly appreciate the support and professionalism of Chen Immigration Law firm. Although it took me a long time to gather all my documents but attorneys from were never late in replying to any of my concerns. They were extremely meticulous in analyzing my documents and made sure all my supporting exhibits were appropriate. In only 30-days my EB2/NIW was approved and I'm sure it was due to their experience handling of my case. I'll certainly recommend others to consider hiring Chen Immigration Law Assoc. for any kind of immigration purposes. One of my friends is already in touch with them after hearing my success story. I sincerely appreciate their time and effort in preparing my case.

- A. R., Postdoctoral Scholar

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

The folks at Chen Immigration know what they are doing and did a fantastic job. They are extremely knowledgeable and helped me throughout the application process.

- A. S., Principal Consultant

I had worked with Chen Immigration group for my O-1A visa first and then retained with them for my I-140 petition under EB1A category. Their services are rapid and prompt with an affordable fee structure. They also have very high success rate of approvals. They have taken utmost care on all the required documentation. They usually respond to my questions in 1 business day. I highly recommend Chen Immigration group for my fellow colleagues for their petitions under various categories.

- R. V., Chief Technology Officer

Chen Immigration is by far the most professional and meticulous group I have come across. The entire process, right from the evaluation by Victoria Chen, to the final submission to USCIS is systematic and diligently planned. Each and every question is answered and at no point does one feel helpless. The letters are expertly drafted. Kudos to the team and Ms. Chen.
