Client Testimonials

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.

- L. S., Postdoctoral Fellow

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

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

- A. S., Principal Consultant

I highly appreciate the support and professionalism of Chen Immigration Law firm. Although it took me a long time to gather all my documents but attorneys from WeGreened.com were never late in replying to any of my concerns. They were extremely meticulous in analyzing my documents and made sure all my supporting exhibits were appropriate. In only 30-days my EB2/NIW was approved and I'm sure it was due to their experience handling of my case. I'll certainly recommend others to consider hiring Chen Immigration Law Assoc. for any kind of immigration purposes. One of my friends is already in touch with them after hearing my success story.

Success Stories: A Ph.D. Student from Germany Pursuing Brain and Cognitive Sciences Secured I-140 (NIW) Approval After Presenting a Personalized Petition

Everything went well and I’m glad I went with Chen Immigration Attorneys. I was deliberating doing it all by myself, but I’m glad I didn’t, since this was so much easier, and I felt assured throughout the process that everything was done to maximize my chances of securing approval. Communication was easy through the webtool and the instructional documents were clear. I’m also happy that the attorneys suggested to go with only one independent reference in my particular case, since getting references just adds extra time and is a hassle. All around happy with my experience.
