November 20th2023 we received another one EB-1A (Extraterrestrial with extraordinary abilities) approval for a visiting researcher in the field of semiconductors and microelectronics (Approval notice).


General area: Semiconductors and microelectronics

Position at the time of submission of the file: Visiting scientist

Native country: China

State of residence at the time of filing: Massachusetts

Approval notice Date: November 20th2023

Processing time : 7 days (Premium Processing requested)


Summary of the case:

Our client is a visiting scientist who proposes to continue his work in the field of semiconductors and microelectronics. He is currently focused on the development of novel spintronic devices, which have already significantly advanced the national interest through advances in spin injection technologies. His research has been published in some of the most prestigious journals and conference proceedings in the field, resulting in a total of 90 peer-reviewed articles and 3 patents.

So he asked for help from North American Immigration Law Group file an I-140 petition under the EB-1A (Extraterrestrial with extraordinary abilities) category. The goal was to present his achievements in the best possible way. We have carefully evaluated the veracity of his credentials and highlighted his substantial merits in his field in the EB1A petition file. This file was then forwarded to USCIS for a further decision on his case.

We presented some key information in its EB1A petition file, which determined the positive result.

  • We concluded that his research addresses some of our nation’s most pressing issues, including improving technological efficiency and innovation.
  • We highlighted that his publications accumulated 1,675 citations from at least 65 countries. Using his research, his peers have gained a deeper understanding of the complexities involved in this study and its importance in superconducting systems. The implications of these findings are far-reaching for advancing the field, as they support intensive scientific research aimed at improving superconducting devices, spin-based electronics, and quantum information processing.
  • Furthermore, we mentioned that he has conducted 108 peer reviews to date. It is evident that our client’s impact is once again exemplified by its involvement in conducting peer reviews and evaluating scientific manuscripts for prestigious journals. Additionally, his role as associate editor of the Journal of Semiconductors solidifies his position as a prominent figure in the scientific community.
  • These contributions, coupled with his distinctive publication record, active conference participation, and relentless pursuit of cutting-edge research, clearly demonstrate his irreplaceable efforts to advance the field crucial for future technological advancements.

Additionally, our client’s work on spin injection technologies was funded by the French National Research Agency and the National Natural Science Foundation of China. This funding supports projects that promote fundamental and targeted research, technological innovation, technology transfer and public-private partnerships. His work contributed to the development of semiconductors and microelectronics and advanced spintronics, leading to the creation of more efficient and faster electronic devices.

To further strengthen his file, we have included 4 letters of recommendation in his EB1A petition file obtained from his fellow experts in the field. One of them made the following statement:

“As a researcher working in the same field, I confirm that (the client’s) research has not only received worldwide acclaim, but has also solidified his status as a distinguished and highly respected figure in the field. His superior know-how and talent for developing new materials for advanced microelectronics, spintronics, and optoelectronics have truly distinguished him from his peers. From his work with spin injectors to his pioneering advances in spinterfaces and resonant tunneling in magnetic tunnel junctions, the long list of his landmark ventures attests to his rare combination of considerable skills, unique perspective and meticulous approach to the research.

Wegreen managed to obtain more than 32,000 approved files and once again achieved a remarkable feat by obtaining EB1A approval for this client. Our client received this approval only 7 days after we submitted their case to USCIS. Thanks to the premium processing service to achieve accelerated results. We are pleased to have been able to convince USCIS of our client’s unwavering commitment to continuous research and ability to consistently produce exceptional results, making them a global leader in technological advancements in optoelectronics. We express our gratitude to our client for choosing our law firm, as we believe our contribution has been an important part of their success.
