Position at the Time of Case Filing: Postdoctoral Research Associate

Country of Origin: China

State of Residence at the Time of Filing: New Hampshire

Approval Notice Date: September 21st, 2021 (NIW) and December 1st, 2021 (EB-1A)

Case Summary:

An EB-2 NIW (National Interest Waiver) petition approval was granted to a postdoctoral research associate with a Ph.D. in nuclear physics from China. Before starting off with a client-attorney agreement, the North American Immigration Law Group judged his provided credentials to determine his NIW’s success. We asserted that we could lead him to obtain the national interest waiver after a thorough evaluation only.

Our team thus, followed a proficient process of analyzing his background, paperwork, and the associated evidence, and were then only confident that they were enough to persuade USCIS and get our client the NIW approval.

  • Since, the method of obtaining a green card involves two steps, that is, filing an I-140 petition and an I-485 application, our client even retained us for another I-140 petition under the EB-1A (Alien of Extraordinary Ability) visa category and I-485 applications as well.

We highlighted the following aspects to make his case a success:

  • The 26 peer-reviewed scientific articles and 1 arXiv preprint he published in some of the most discerning, high-impact journals in his field of nuclear physics.
  • A splendid record of obtaining 933 citations in other peer-reviewed journal articles.
  • Cited by researchers in at least 37 countries.
  • Also been invited to review and evaluate the work of his peers no fewer than 5 times, serving as major evidence of his supremacy in the field.

Moreover, our client’s research addresses some of our nation’s and the world’s most pressing issues, including furthering scientific knowledge of the fundamental nature of the universe. His strong background in particle physics, dark matter, and the development of new physics models has allowed his research to be particularly original, resulting in his success in fundamentally transforming nuclear physics research. He is particularly well-known for his contributions improving physics models beyond the standard model with stopped K+.

  • Our client’s study has even received funding from the National Science Foundation which enforces a competitive, merit-based review process in which reviewers evaluate projects to ensure that they are of the highest quality. Their support of his work thus singles him out as a top researcher in the field conducting work that directly serves national interests.

Furthermore, considering the impactful articles our client has published, the numerous citations his work has attained, and the funding it has been granted, has proven him to be a prominent and influential member of the field, having provided many important and influential contributions that are addressing the needs of both the academic and greater community.

  • Also, the following 2 statements are excerpted from two of the four recommendation letters submitted:

“As [client] determined that photomultiplier tubes with smaller pores exhibit better performance in magnetic fields, his work directly benefits this area of research and is indicative of his importance to the nation. Because of his importance to the research community and the interests of the United States, I firmly endorse his continued research.”

“[Client] is an outstanding researcher that has completed original work on the strong interaction, one of the four fundamental physical interactions. [Client’s] prolonged research efforts in this field are key to meeting the United States’ goals to deepen the understanding of the universe and maintain the United States’ leadership role in global research.”

All of this evidence is fully supported and corroborated by letters from internationally recognized experts in the field who have used our client’s work in their own research endeavors and attest to its influence and major significance. The totality of this evidence shows that our client is one of that small percentage who has risen to the very top of his field and has sustained both national and international acclaim.

  • He is therefore fully qualified as an individual of extraordinary ability in his field of expertise.

We are thrilled that our team was once again successful in persuading USCIS of the importance of our client’s research in the United States. Thus, he was granted not only EB1-A approval in just 9 days (thanks to Premium Processing), but also, NIW in the gap of 3 months only. He even received his I-485 approval in another few months. We would sincerely like to thank him for choosing our law firm for the I-140 and I-485 petitions and wish him success for his future endeavors.
