One word to define Chen immigration: 'Professional'

First of all, I want to thank the immigration team for their timely and excellent services. They were absolute joy to work with and the team was thorough, experienced and well placed to provide me excellent reviews, advice throughout my EB2-NIW application process. I have already recommended a few of my friends who already echo my sentiments and will continue to refer Chen Immigration services to anyone who seek my advice.

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 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

Three of my friends who already got green card in EB1 category with the help of Chen immigration recommended me to contact this firm. They gave me free evaluation and approve and refund policy for my EB1B. I don’t know about other firm but I can say that I had a very good experience with Chen immigration. My attorney guided me on every single step and never got irritated even if asked same question several times. I got the answer of all my questions within 24 hours of time. As they promised, they wrote very strong letter of recommendation and drafted my petition within timeline. I was impressed the way they presented my case in the petition and as a results my case got approved in 7 days. I would strongly recommend Chen immigration to anyone trying to get green card under EB1 category. As I heard from my friends and I also experienced that they are the best with impressive team of attorneys. Thank you so much Chen immigration. It would not have been possible without your help. You are doing really good job. Keep it up !
Highly Recommended !!!!
