Mangmang Cai

My wife and I are very happy for having chosen Dr. Cai and his law firm for helping us file application for a green card through marriage sponsorship (F2A category). In approximately 6.5 months since the day of filing with USCIS, I received my green card in hand! Dr. Cai and his staff were extremely ...careful and thorough when it came to reviewing our credentials and putting together a series of supporting documents that were approved by USCIS right away. They were always responsive to my questions while my case was pending. They have a wonderful online system where you can easily drop all your documents and see the progress and updates for your pending case. I highly recommend Dr. Cai and his firm for your immigration needs.

My O1A visa was got denied through company providing Legal service (Fragomen). Felt very dispointment and recommended by my friend to Dr. Cai for O1A petition service. Very impression by the fast action and high quality service provided by Dr Cai' team. Using the same petition materials, my O1A r...e-petition was got approval. Thanks for Dr. Cai and his team for great helping and supporting!

Dr Cai’s team is very professional and helpful in assisting my petition of NIW. With their well prepared petition letter and supporting materials my NIW was approved after 6 months of submission to NSC. The best part is that they are easily to reach and replies my email within 12 hours all the time. ...I would recommend anyone who need immigration help to talk to them even if you are not fully ready. They will give you the most professional legal advice.

My NIW case is approved after 11 month. Dr. Cai and his team have provided excellent service to guide me through my NIW petition. The communication is great and they always respond within 24 hrs. The team has very strong scientific expertise and knows how to prepare the paperwork to show the best of ...the applicant. I highly recommend them to any scientist/engineers who needs help with immigration.
