Case Summary:
An M.Sc. degree holder in polymer engineering, a Ph.D. candidate from Iran contracted with our law firm to help him in yielding his I-140 NIW (National Interest Waiver) petition. North America Immigration Law Group’s experience in preparing the NIW case is unmatched and our client knew that we would walk miles to get him his NIW approval. He provided us with all the necessary paperwork to be sent to the USCIS. Thus, we countersigned the attorney-client relationship and began preparing a solid case on his behalf by citing the following:
- Firstly, we established his research on preparing polymeric stimuli-responsive membranes with water-soluble polymerization initiators to improve industrial-scale water treatment by decreasing membrane fouling and increasing water flux recovery. We were certain that his research in this field seems to be of great importance because he has developed novel polymer synthesis methods and materials with manifold benefits.
- Since his research is relevant to environmental protection, public health, and manufacturing, there is an urgent national need for his continuing contributions, which are vital to wastewater remediation. The United States’ water treatment plant infrastructure urgently requires new technological solutions to meet increasing demands.
- At the time he was filing for his NIW, he already had established an extraordinary record of success, including the 216 citations. These citations indicate that our client’s research efforts are noteworthy. Moreover, his research has resulted in 20 peer-reviewed journal articles (4 of them first-authored), 2 books, and 1 patent. This noble work reflects his peers’ recognition of the value of this research. We also observed that due to his knowledge and expertise in the field, he has been regularly invited to conduct peer review for elite journals in the field, and he has completed at least 2 peer reviews to date, confirming that he is seen as knowledgeable and well-regarded in the field.
- We highlighted his record of successful research in an area that significantly furthers U.S. interests, also, he offers contributions of such value that, on balance, they would benefit the United States even assuming other qualified U.S. workers are available. Further supported his case by adding four recommendation letters in his petition packet, and one of his recommenders contributed the following discernment:
Therefore, USCIS spent 11 months adjudicating our client’s petition packet, however, without any further request of evidence (RFE), USCIS granted him the NIW case approval, and we sincerely thank him for choosing us and for letting us be a part of this incredible journey with him for his I-140 application.
