Client Testimonials

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.

- M. R., Physician

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 !

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.

- D. T.

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!
