Summary of the case:

A Chinese customer with a Ph.D. in Biology, Biomedicine and Chemistry contacted us to help him file the I-140 NIW (Renunciation of national interest) petition; we therefore called on our team of experts to build a convincing case. We have included details of his professional and academic career in his petition file to support his request for NIW category.

We presented him with his university diploma:

  • He has also been actively engaged in the field of agricultural sciences as a postdoctoral research associate.

And that his proposed project involves genetically modifying genes related to crop growth and development in order to improve crop productivity and facilitate plant breeding.

  • Additionally, due to its obvious national significance, the client’s research was supported by funding from the National Natural Science Foundation of China, the National High-tech Research and Development Program of China, the Ministry of China Agriculture and National Science Foundation. This funding is reserved solely for research aimed at improving public health and welfare, economic prosperity, and national security.

On the other hand, we highlighted that his academic results have earned him several publications and citations:

1. His research resulted in 5 peer-reviewed journal articles (2 of which were written first).
2. His publications have been cited 23 times according to Google Scholar.

Not only that, but the recommendations included an excellent review of his work, one of which (out of four) is cited below:

“(Client) is an agricultural scientist who works at the forefront of his field of study and is one of the first to report on the functional characterization of corn AGO proteins in small RNA pathways. Its research on corn biology and efforts to understand genetic/molecular resources for improving crop yield and quality are therefore of great importance to global food demand and contain inherent value for societal and economic.

Based on this multi-factor assessment, it is clear that the client’s education, experience, expertise, documented successes, influence in their field, and plan have overall positioned them well in their field of expertise.

We are therefore very proud that our client obtained his NIW approval despite a long waiting period. It was an incredible journey with him. We wish him the best in his future endeavors.
