My experience with them with filing my EB2-NIW petition steamily positive. They are professional, well-mannered, timely, and helped us steered through the complex petition process.
I talked with couple of others law firms but find out that Chen Immigration has refund policy, means that they do their homework according to your case before file the case. Which give me more confidence. At the end I figure out that the work very hard to prepare my case. I highly recommend to people if they want to apply for I-140.

- P. N., Postdoctoral Fellow

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.

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.
