I am very satisfied with lawyer Cai hai's service, and I highly recommend him. I am Ph.D. in biology and I got a green card under EB1A with his help. His advice was precise and professional which I never knew if I prepare it by myself. I appreciated that he always replied my email quickly. Lawer Ca...i and I corresponded via email and Dropbox and I didn't have to go to this office which saved me a lot of time. He is a responsible and reliable treat lawyer.

Due to my friend's recommendation, I was Dr. Cai's client of EB1A green card petition. I remember Dr. Cai responded my first email very quickly in the middle of Saturday tonight, I guess his team is working very hard. My case was approved very smoothly without any issues because of his professional, ...responsible and effective team. He quickly answered me any kind of immigration questions free of charge. I recommended other friends to Dr. Cai. All their EB1A cases were approved. So I think Dr. Cai is your best lawyer option for your immigration petition. Highly recommended!!!
