Dr. Cai and his colleagues are very professional. They prepared all the documents for NIW. In my case, I waste a lot of time to send out my petition to service center. I know the petition received date is the priority date. However, I am shamed about my publications, and wait until more papers are p...ublished. They are very patient and help me finish it. So do not like me, just follow the instructions from Dr. Cai and his colleagues, finish your case as soon as possible.

Mangmang and his colleagues (Don and Sha) were super helpful with my case. They answered all our questions and managed to build a very good case on time. Their expertise in science and in immigration laws makes them the perfect immigration lawyers for scientists. I highly recommend Mangmang Cai and h...is team to all my friends!
