I would like to thank Chen immigration group for their excellent service and great efforts in working on my case. They are very efficient, responsive, and professional throughout the entire process. I got my NIW I-140 approval in 8 months. I do not have a strong background but they were able to work on my case professionally and provide very good guidance, strategies, letters, and other documents for my case which lead to my NIW approval. I am very glad to choose this law firm and would highly recommend this law firm for anyone who wants to work on the GC application process (EB1, EB2 NIW, etc.)
