Mangmang and his colleagues helped me with my NIW case. They were very responsive and competent. I did appreciate their expertise in science in addition to immigration law as it is needed to build the case. As soon as I provided all the documents, they built the case in a few days, I reviewed it, and... it was sent. My NIW got accepted in 4 months, way earlier than I expected. I highly recommend Mangmang Cai!

I'm working with Dr. Cai and his team on both my EB1A and NIW cases. Dr. Yang and Sha helped with my case. My area is in EE and Dr. Yang is very familiar with this area and did a good PL. Sha is responsive and quick on my documentations. Dr. Cai reviewed the materials and also answered a lot of my qu...estions - including eb1-b ones which I didn't pay them. Although I'm still fighting for my EB1-A, I do recommend their service.

I started working with Dr. Cai about 2 years to file my EB1 green card application. They drafted very professional petition letters for my I-140, putting together a very coherent presentation of my scientific contribution. And of course, the I-140 got a speedy approval! I continued working with Dr.... Cai for the I-485 applications. Due to the retrogress of EB1 in certain countries, this process was long and full of anxiety for me. Dr. Cai and his team have never dropped the ball during this 15-month period. Whether I had a question or needed support, they were there to help. Eventually, there came the RFE for the I-485. They worked with me through this final step, until my green card was approved. I am extremely happy and satisfied with Dr. Cai and his team. They are not only true experts but also very passionate and supportive which can be much needed to work through the green card application process.
