I was fortunate to come across Chen immigration when I started looking into my options for green card. I quickly realized they are extremely professional and would handle my case at a personal level. Indeed, over the last 1 year they have performed beyond my expectations.
Chen immigration team gave me a free evaluation after assessing my portfolio. Their timing for my case has been impeccable at every step. The lawyers have worked with me as a team. Communication with the whole firm has just been outstanding. I would recommend Chen Immigration extremely highly to all my friends and anyone who is in my shoes and looking into the process for Green card.

I would like to thank the Chen Immigration team for getting my I-140 (EB-1B) approved with no RFE. I choose premium processing and the case was approved in 13 days. The team is very professional and helpful in every step on your way to the approval. I had many questions from time to time during the preparation process and they were answered in a timely manner.

I applied for EB-2 trough North America Immigration Law Group. I got the I-140 approval in one month ! I would like to greatly appreciate for their professional jobs. According to my interaction with them in filling out the I-140 application during several months, I found them very trustful and expert.

In addition, the application fee is cheaper that other immigration attorneys. Thanks a lot
