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

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.

- K. K., Research 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

The Chen Immigration Law group was recommended to me by a fellow postdoc at a networking event. He claimed that if they say that my credentials are good enough to file a case for a green card then it is almost certain success. He was absolutely right.
After evaluating my credentials we decided to apply under the EB2-NIW category. Overall, it was a pleasure working with them. All my questions were answered promptly and to the point. Although the communication was only through emails, it was very effective. They made very clear to me what documents are necessary and how to obtain them and they drafted amazing reference letters and the I-140 petition letter. The price was very reasonable (the best I could find) and they always keep their timeline.
I am really grateful for their service and I highly recommend them. Thank you so much!

- P. F., Post-doctoral Scientist

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.

- T. K., Research Scientist

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.
