Client Testimonials

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. I sincerely appreciate their time and effort in preparing my case.

- A. R., Postdoctoral Scholar

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 !!!!

- Dr. S. R., Assistant Professor

My EB1A was approved four days after USCIS received my documents. I'm very impressed by the professionalism and enthusiasm of NAmILG during preparation and filing of my case. The prompt approval of my case wouldn't be possible without the expertise and hard working of the attorneys of NAmILG.
One of the advantages of NAmILG I want to point out is they drafted all of the required letters, which saved huge amount of time for me. I'll definitely recommend to my friends who are looking for immigration attorneys.

- T. W., Postdoc

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.
