Case Summary:

A postdoctoral fellow from China hired North America Immigration Law Group ( to help him obtain a green card. Our client’s extensive experience in the field of epidemiology made him a suitable candidate for EB-1A (Alien of Extraordinary Ability). As a result of Premium Processing, our client received an approval notice from the USCIS just eight days after we filed the case on his behalf.  

Our client’s publications (55 peer-reviewed scientific articles, 1 book chapter, and 1 book translation), 18 instances of peer review service, and the 709 citations of his work have placed him at the top of his field. We demonstrated that his insights advance the work of other scientists within his area of study and that his research on the epidemiology of deafness and clinically significant diseases greatly benefits the United States.

To further reinforce our EB-1A petition, we advised our client to approach other authoritative figures in his field to solicit recommendation letters. Four experts agreed to lend their support and their letters were incorporated into our meticulously prepared petition packet. According to one of these letters, “[Client’s] outstanding education, coupled with his extensive research history, has turned [Client] into one of the central researchers in the field of epidemiology studies on hearing loss due to genetic mutations today.”

We are pleased that the combination of our client’s strong credentials and our diligent efforts convinced the USCIS to approve this EB-1A petition. This approval is yet another example of North America Immigration Law Group’s dedication to helping every client achieve their goal of obtaining a green card.
