Client Testimonials

It was a privilege to work with Chen immigration attorneys during my NIW I-140 application. They were really professional and kept the deadlines depicted by the client-attorney agreement. They will answer your questions within a day with the maximum clarity. I would definitely recommend them to anyone looking to apply for a NIW green card. Thanks once again and keep up the good work.

- I. S., Research Scientist

It was a long and tough journey to prepare the EB-1A I-140. However, with the professional assistance and prompt feedback from the NAIL firm, this process has become much easier. They always stick to the deadlines that have been promised (preparing reference letter in 10 days, petition letter in 10 days). Thank you Chen associates for your enormous help, which helped me get my case approved one day after USCIS received my Form I-140. I will absolutely recommend you to every of my friends who will be applying for the green card in the future.

- J. L., Postdoctoral Fellow

My I-140 (NIW) was approved this week!
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 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.

- A. S., Principal Consultant

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.
