Case Summary:

A prominent postdoctoral fellow from China selected North America Immigration Law Group ( to help him file an EB-1A (Alien of Extraordinary Ability) petition on his behalf. Our client, who is immersed in the field of cell biology, has extensive academic and practical experience progressing the field.

Our client obtained six recommendation letters to fortify his EB-1A case, all of which were contributed by other leading cell biologists in the field. According to one of his recommenders—a well-known professor—our client is “… a foremost researcher in cell biology who has made substantial advancements in cell developmental research. He conducts pioneering research on mechanisms of action at play at the organelle level. There is a profound need for [Client’s] research, and I therefore recommend that he be enthusiastically supported.”

Client’s Credentials:

Our client’s illustrious career is peppered with scholarly and professional accomplishments. One of our duties was to account for and summarize these achievements and incorporate them into our EB-1A petition dossier. Here are several of them:

  1. Citation and Publication Record:

When we filed the case, our client had published 11 journal papers and his work had collected 181 citations.

  1. Research Endeavors:

Our client’s work focuses on membrane asymmetry and protein transport. By researching organ development and protein trafficking, our client is advancing the field’s knowledge of gene therapy targets.

  1. Peer Review Experience:

Our client’s insights are extremely important to other researchers in the field and this is clearly seen through his impressive peer review experience. At the time of filing, our client had conducted 40 peer reviews for multiple high impact scientific journals.

Legal Strategy:

Our legal team worked diligently to compile all the information we had gathered into a convincing petition letter. We demonstrated that our client’s research efforts are very important to the United States, particularly its medical sector. We established that our client’s copious accomplishments in the field are rarely achieved, and even then, only by the best researchers in the field.

In Conclusion:

Largely thanks to Premium Processing, the USCIS only spent a week adjudicating our client’s EB-1A case. Even so, we have no doubt that our meticulous presentation and our client’s solid credentials paved the way for case approval. We congratulate our client on this milestone and thank him for selecting us to represent his case.
