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'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
I applied for EB-2 trough North America Immigration Law Group. I got the I-140 approval in one month ! I would like to greatly appreciate for their professional jobs. According to my interaction with them in filling out the I-140 application during several months, I found them very trustful and expert. Therefore it is my pleasure to highly recommend this firm to persons who like to apply for EB-2 green card or related ones. In addition, the application fee is cheaper that other immigration attorneys. Thanks a lot- R. N., Independent Research Scientist
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. Their letters were of top quality and would recommend them any day for any immigration related matters. Kudos to North America Immigration Law Group's team. Keep up the good work!!!- A.

My I-140 (NIW) was approved this week!- M. R., Physician
I was fortunate to come across Chen immigration when I started looking into my options for green card. I quickly realized they are extremely professional and would handle my case at a personal level. Indeed, over the last 1 year they have performed beyond my expectations.
Chen immigration team gave me a free evaluation after assessing my portfolio. Their timing for my case has been impeccable at every step. The lawyers have worked with me as a team. Communication with the whole firm has just been outstanding. I would recommend Chen Immigration extremely highly to all my friends and anyone who is in my shoes and looking into the process for Green card.
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
