Case Summary:

Nebraska Service Center (NSC) approved the EB-1A (Alien of Extraordinary Ability) petition of a Chinese postdoctoral researcher 13 days after filing with Premium Processing (PP). PP is a paid option that significantly reduces the adjudication timeline from 4-9 months to less than 15 days.

Before filing the EB1A petition on our client’s behalf, North America Immigration Law Group ( previewed his credentials to ascertain his suitability for this visa category. The information we collected was incorporated into the petition dossier we prepared. The following are some of the points we took note of:

  1. Our client had secured a Ph.D. in Information Technology from a well-known institution in the United States. He possesses exceptional skills and expertise in the field of data science; especially noteworthy is the fact that his research is focused on recommendation systems and privacy. These credentials served as important evidence to allow our client to further his career in the United States.
  2. Not only did our client have excellent technical expertise, he also demonstrated scientific fervor through years of research. The fruits of his labor were 16 peer-reviewed scientific articles and a conference abstract published in top-tier journals. At the time of filing, these publications had amassed 305 citations. His expertise is also evident in the 50 reviews of his peers’ work, conducted on behalf of top-ranking journals. Additionally, he is the holder of a US Patent. These impeccable achievements were highlighted in the comprehensive EB-1A petition dossier we prepared.
  3. Knowing full well that endorsements from experts can immensely fortify the case, we encouraged our client to obtain recommendation letters from his peers. He managed to collect 5 recommendation letters from other data scientists, one of whom stated: As user safety is one of the most important topics in this field at present, especially where children are concerned, it is clear that [Client’s] work greatly benefits a considerable portion of the population. Thus, I unequivocally support his extraordinary work.”

After receiving EB1A petition approval, our client decided to retain our I-485 services for himself and his wife. We thank him for the trust he has placed in us, and we promise him our unflinching support and assistance throughout the final portion of the green card journey.
