Mangmang Cai

Mangmang and his assistant Xiaoping helped me with green card application. They are very efficient at organising all the materials, and very patient when there were additional amendments. They responded promptly every time and sent out all materials quickly, and all processes went very smoothly. They... also provided me with additional information regarding to other visa issues without any additional charge. Their Youtube channel is very helpful too. Overall it was a very pleasant experience working with them.

I approached Dr. Cai's team based on the recommendation of multiple former labmates. Dr. Cai reviewed my CV and responded with his strategy recommendation within one day. After I hired him, he provided very useful templates for the application documents, clearly showing his expertise in presenting ac...ademic credentials for immigration purposes. I wrote a few pages of material on my technical achievements, which his team repackaged into a petition letter and several recommendation letters. It took me and his team about six weeks to write and polish the documents and to identify referees. After I got the recommendation letters signed, it took his team about a month to put together the package and submit it. I just got my NIW approval notice after 6 months. I am very satisfied with their service.
