Case Summary:

Last year, a talented postdoctoral associate from China hired North America Immigration Law Group to help him with the first step of the green card process: filing an I-140 petition. When he first contacted us, he wanted to be evaluated for both EB-1A (Alien of Extraordinary Ability) and EB-2 NIW (National Interest Waiver). After thoroughly reviewing his qualifications, we determined that he was entitled to file his I-140 petition under EB-1A.

EB-1A is upheld by a very high standard of law and unsurprisingly, has some of the lowest approval rates. Thus, if we wanted our client’s EB-1A petition to be approved, we had to convince the USCIS that he has risen to the top of his field and has obtained national/international acclaim for his work. Leaving no stone unturned, we accumulated as much information as we could on our client’s professional and academic performance. Here are some of the things that we included in his EB-1A petition dossier:

  1. We noted the 515 citations collected from his 15 published papers. Using these numbers, we demonstrated that various other researchers around the world are using our client’s findings to progress their work, which in turn, advances the entire field of medical physics as a whole.
  2. We informed the USCIS that only leaders in the field are invited to conduct peer reviews for scientific journals. By detailing the 30 times our client judged the work of other researchers, we proved that his insights are highly valued by members of the medical physics community.
  3. Based on the research summary furnished by our client, we were able to determine the focus of his research: applying nuclear physics in medicine, computed tomography (CT) image reconstruction, and nucleon structures study. We established that his work is important to the U.S. medical sector, especially in progressing nuclear medical imaging including MRI, PET, and CT scans.

To strengthen our client’s EB-1A petition, we encouraged him to reach out to other experts in the field for recommendation letters. We needed them to verify that our client is an asset to the nation. To our delight, our client returned with five signed testimonials, all of which contained supportive statements such as this: “[Client’s] steady stream of major achievements in particle physics has propelled him to the forefront of a very fast-paced and competitive field. In consideration of his record of achievement to date, it is clear to me that [Client] will continue along this trajectory of success for many years to come. Without [Client’s] continued participation in his research, I anticipate lengthy delays in scientific progress in the field as a whole. As the most prominent names in the field of particle physics, [Client] has considerably increased awareness of these new advancements, strengthening scientific research throughout dependent fields.”

Thanks to Premium Processing, the USCIS only spent 10 days reviewing our client’s petition before granting their approval. This EB-1A approval is yet another example of our law firm’s commitment to helping every client attain a petition approval. Using our D.I.Y. I-485 packet, our client filed an I-485 application and got his green card within 3 months. We congratulate our client and wish him well with his continued research.
