Client Testimonials

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 !!!!

My EB1a petition got approved last week without any RFE. WeGreened worked with me very very closely at every step right from the beginning. I really appreciate the draft of recommendation letters you developed for me. Team Victoria is really great, and highly professional in services and timely responses. This is such an awesome experience working with you. Thank you !!

- S. S., System Analyst

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

A real pleasure to work with Chen Immigration. I'm very satisfied with the process and, of course, with the result!
It was a persistent, systematic everyday job of their team for several months, tons of e-mails, all replied professionally. No need for a single phone call! No nerves, no hash, no mess, just persistent professional work that resulted in my approval.
Yes they ask for many supporting documents and evidence but the result is a very strong case approved without any RFE. That's extremely important to save time and nerves.

- A. B.

I decided to choose North America Immigration Law Group based on some positive feedback and experiences that some of my friends had with. Working with them was great. They are very supportive and professional and they are well familiar with the rules and process. Everything was delivered on-time exactly as they promised. My application was approved in less than 60 days
I highly recommend them to anyone who needs their service, specially for NIW category. I already have referred some of my friends to Chen Immigration Law Services and they are also very happy and satisfied with their service.

- M. M., Postdoc

When i looked at all the reviews for the immigration firm, Chen immigration caught my attention for two reason, effective clear communication and their experience to approve otherwise difficult cases. After the initial free evaluation by their experienced attorneys they presented me with step by step instructions and options. I took a week to understand and signed the contract with them. My only concern at that time was not seeing the firm in person as everything is online, However that concern was gone as i saw their work ethics. They are super professional and respect the timelines and deadlines. they meticulously prepare all the documents, which is really important for such cases. I had a wonderful experience with them. I had already recommended two of my friends to hire them. I hired them for both I-140 and I-485. My I-140 was filed with PP and I received the approval in 8 days.

Success Stories: Technical Designer from India in the Field of Civil Engineering Secure NIW in Less than 6 Months with Our Law Firm

After having graduated with a PhD degree in Civil Engineering from Arizona State University in May 2016, I waited for almost 3 years to improve my credentials before reaching out to Chen Immigration Attorneys. I heard great things about them through my personal connections, and I finally reached out to them on April 30, 2019 for an evaluation of my profile for a possible green card petition through EB1B. I received a very positive feedback from them within 24 hours. They advised to pursue the option of the self-petition, EB2-NIW along with the employee sponsored EB1B. They went over in detail the merits of this combination, associated fees, payment plans, and the required documents. It took me 6 weeks or so to get everything squared up with my employers, and by mid-June,2019 we had a signed contract and the Chen Associates were officially engaged to work on the EB2-NIW petition. They have a very systematic approach to the document preparation with several guidelines explaining the process flow step-by-step. They self-appoint strict timelines for any major tasks they undertake; and always end up fulfilling them. Throughout this process, they promptly answered all the questions I had; and came across as very knowledgeable of the entire process and very efficient in communicating the requirements in simple language. Once I finished working on summarizing my research contribution in their specific format and prepared the list of recommenders, Chen Associates promptly started working on my case and produced the draft letters by mid-August 2019. Once the letters were signed and finalized, they prepared the draft petition by mid-September 2019. In my experience the time-consuming parts of this process was for me to summarize my research contributions in their specific format and securing the signed letters from the recommenders. Once the petition, recommendation and employment letters were finalized, they provided a complete list of supporting documents which are mainly immigration and professional experience related; and were relatively easy to secure. We finally, submitted the EB2-NIW petition to the USCIS on October 17, 2019. After precisely 164 days, my EB2-NIW petition was approved by USCIS on March 31, 2020; without any RFE’s. I thoroughly appreciate the work done by Chen Associates; and I would highly recommend them for any of your immigration needs.
