顾客见证

Many thanks to Chen immigration & Attorneys for their great help, and I had a very good experience working with this professional attorney team, they prepared high quality recommendation letters and petition letters, provide guide in detail and response questions in time, I am lucky to have such a team to help me get the approval. I strongly recommended them to all who are seeking green card.

- Y. H., Postdoctoral Research Associate

I had a great experience working with Chen Immigration Law Group. I applied for EB1A premium processing and the case was approved within 2 weeks without any RFE.
I was impressed with the quality of petition letter and the reference letters drafted by their team. Although my field is highly technical, the attorneys seemed highly knowledgeable and were able to present my research in a manner which was easy to understand, impressive and yet not 'over-selling'.
They went over my research/citations meticulously and were able to catch mistakes which honestly I would have missed if I was preparing my own case. They were also very prompt with replying to any questions I had during the process.
In short, I would strongly recommend them to all who want to get through the green card process without stress.

- P. J., Postdoctoral Researcher

It was fantastic to work with Chen Immigration Law Group. I got my I140 approval just in 4 months.Chen Immigration Law Group is a very professional company.They answered all my questions with timely manner and prepared my I140 package really good that I received my approval way before than I expected. I also really like their online service which makes everything easy to understand and to follow the instructions correctly and help you to handle such a complex paper work efficiently.

The folks at Chen Immigration know what they are doing and did a fantastic job. They are extremely knowledgeable and helped me throughout the application process. Their letters were of top quality and would recommend them any day for any immigration related matters. Kudos to North America Immigration Law Group's team. Keep up the good work!!!

- A. S., Principal Consultant

Many thanks to NAmILG/Chen Immigration for the quality and efficiency of their services. They have always replied very fast to any of my requests or questions. They have provided me with very clear answers and guidelines to navigate the I-140 application process. Their preparation of the file and their drafting of letters were thoroughly thought out and meticulous. I consider they have played a key role in the success of my I-140 application.
I would highly recommend Chen Immigration for their professionalism, honesty, and straightforwardness.

- P. A. M., 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.
