I worked with Dr. Mangmang Cai for reviewing my I-485 package for my EB-1B application. Not only does Dr. Cai have an eagle eye for detail, but he also has deep legal expertise in his subject matter, which employs to give excellent advice. Even after my I-485 was submitted, for the next 11 months I ...was in constant contact with Dr. Cai, emailing him from time to time with questions, that he very patiently and promptly answered. I'll even add that my Green Card was finally expedited and arrived in 10 months from I-485 application date (while USCIS schedules showed 12 to 20 months), thanks to his astute advice! Highly recommended!

I applied my NIW (I140) application with Mangmang Cai and I got approval notice on Dec 18 2021. I am not strong case because I only have master's degree in Chemistry. However, his team was really helpful when I applied NIW. Finally, I got the approval letter. Thank you so much Mangmang cai and Yang a...nd Fu!

I have been very impressed by the expertise afforded by various members of this firm. They are particularly well positioned to assist scientists and clinicians with USCIS applications. They extracted the core contents of the major scientific contributions in my CV and crafted an application that was ...concise and effective. EB1A with PP approved in 9 days, no RFE. Highly recommended
