Case Summary:

North America Immigration Law has successfully petitioned more than 32,000 employment-based visa cases. We have developed the most up-to-date winning strategies for the NIW category based on this huge number of successful cases. We were therefore prepared when our client approached us to help her file an NIW (National Interest Waiver) petition on her behalf. We did this by evaluating her credentials and then laying out an ideal petition packet to guarantee the intended outcome.

We noted that in 2018, our client obtained an M.D., and her proposed endeavor, as a medical engineer, is to carry out her research on creating cutting-edge diagnostic instruments through the integration of complementary metal-oxide-semiconductor technology in medical equipment. This will enhance patient outcomes, customized treatment plans, and effective healthcare delivery.

Impressed by our client’s documentary evidence and corroborating testimony from experts in the field, we agreed to take her case and countersigned the client-attorney agreement for an EB-2 NIW petition.

We submitted copies of her diploma and transcripts as evidence of her qualification background. Since that she finished her education outside of the United States, we also submitted a comprehensive advisory evaluation of her academic records. As a result, she is qualified to work in the fields for which she holds a graduate degree.

We also took into account all of her publications, citations, and experience with peer review.

  • She has published 8 peer-reviewed journal articles, 2 peer-reviewed conference papers, and 1 first-authored paper in authoritative peer-reviewed journals.
  • She has not only completed her research in the field and published the results, but her labor has also influenced her peers. In other words, her publications have been cited a total of 14 times thereby demonstrating that these publications are widely recognized and relied upon in the field of medical engineering.
  • Her study has also been funded by the Ministry of Knowledge Economy and the National Research Foundation of Korea. Thus, the fact that her study is financially supported indicates that her work significantly improves the quality of life through technological innovation, especially when it comes to the development of skin problem diagnosis and treatment skills.

Because she has shown expertise in the field of medical engineering and because her proposed endeavor has applications in the development of design and electronic design automation tools, beyond complementary metal-oxide-semiconductor technology, as well as biomanufacturing and bioprocessing technologies, which are formally recognized as critical and emerging technologies, we were certain that her continued work is essential to achieving and maintaining the United States’ technological leadership. That being stated, our client’s achievement of receiving her NIW approval in just 6 days following our submission of her petition to the USCIS is astounding. We are grateful that she selected us to handle her I-140 application, and we also congratulate her on her outstanding achievement and smooth procedure outcome.
