Case Summary:

A postdoctoral research associate from China hired North America Immigration Law Group ( to file two I-140 petitions on his behalf: an EB-2 NIW (National Interest Waiver) and an EB-1A (Alien of Extraordinary Ability). We handle numerous cases in which clients request to file two or more I-140 petitions to significantly improving their chances of obtaining petition approval.

Our client’s research:

His mission-critical research is committed to ‘make a difference’ in the world of weed science. His specialized research on herbicides has pushed the mechanisms behind conventional weed control strategies to the next level of optimization. More specifically, he has analyzed the breadth of impact of herbicidal chemicals on the environment and human health. We used his research as a key element in our petition to prove to the USCIS that his contributions have left a positive mark on various landscapes of American society, including agricultural production and environmental remediation.

Our client’s credentials:

With an aim to prove the legitimacy of our client’s research and its influence, we highlighted some of his key accomplishments in both petitions, which included his publication record, peer review experience, and citation count. At the time of filing, he had authored 39 peer-reviewed scientific articles. Moreover, he had conducted at least 25 peer reviews for highly acclaimed journals and conferences. His work had also been cited at least 121 times by other researchers in his field.

Our client’s petitions were further strengthened by recommendation letters signed by other influential people in his discipline. We used the same recommendation letters for both petitions as they were filed just three months apart. According to one of our client’s recommenders: “[Client] possesses a rare combination of skills and experience that informs and strengthens his research and makes him one of the most highly qualified researchers in the field.

Just one month and 13 days after filing our client’s NIW petition, the USCIS gave their go-ahead on this case. To our delight, his EB-1A petition was adjudicated even quicker than that—less than two weeks after filing. The rapid adjudication was thanks to the combination of Premium Processing (PP) as well as our team’s impressive standard of service. We congratulate our client for securing two petition approvals and wish him the very best as he moves closer to his dream of obtaining a green card.
