顾客见证

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!!!!

I decided to choose North America Immigration Law Group based on some positive feedback and experiences that some of my friends had with. Working with them was great. They are very supportive and professional and they are well familiar with the rules and process. Everything was delivered on-time exactly as they promised. My application was approved in less than 60 days
I highly recommend them to anyone who needs their service, specially for NIW category. I already have referred some of my friends to Chen Immigration Law Services and they are also very happy and satisfied with their service.

It was fantastic to work with Chen Immigration Law Group. I got my I140 approval just in 4 months.Chen Immigration Law Group is a very professional company.They answered all my questions with timely manner and prepared my I140 package really good that I received my approval way before than I expected. I also really like their online service which makes everything easy to understand and to follow the instructions correctly and help you to handle such a complex paper work efficiently.

I heard about this law firm from one of my friends who had high recommendation. Before approaching Chen Immigration Law Associates, I had personally talked to an immigration lawyer whose fee was expensive and the lawyer did not seem much positive regarding my EB2-NIW case. When I first contacted Chen Immigration Law Associates for free EB2-NIW evaluation and heard that my case is eligible for approval or refund, it energized me and made me believe that my case is strong enough too. Though communication was only through email, it was easy and reliable. The timeline set in the contract is always fulfilled. I am really happy that I chose this law firm and I highly recommend it to anyone seeking immigration advice and services. Once again, I am very thankful to the team of Chen Immigration Law Associates for all their effort in making my petition a success.

- O. P.

I greatly appreciate Chen Immigration Law team for all the help and support, and for their very professional service, from the beginning to the end of my I-140 approval!<
My experience with them with filing my EB2-NIW petition steamily positive. They are professional, well-mannered, timely, and helped us steered through the complex petition process.
I talked with couple of others law firms but find out that Chen Immigration has refund policy, means that they do their homework according to your case before file the case. Which give me more confidence. At the end I figure out that the work very hard to prepare my case. I highly recommend to people if they want to apply for I-140.

- M. W. M, Enterprise Applications Administrator and Developer

It was an incredible experience working with Chen lawyers. I got my EB1A approved in 10 days. They were so perfect in their work and and took care of every little detail necessary. Very dependable and very friendly to work with. They were very prompt in answering every of my questions; and trust me they have been very kind to have responded to silliest of my doubts and concerns. I strongly recommend them to all my friends. Needless to mention, I am going to work with them for I-485 as well.
