Case Summary:

Some of the key factors in a solid National Interest Waiver (NIW) petition are a strong proposed endeavor, publication history, citation count, peer review experience, funding history, proven national merit, recommendations, and so on. All of these factors combined make for a strong petition and lead to victory.

So, when we got a postdoctoral scholar working in health sector sensing, we made certain that his work was well-showcased so that he won the approval without an RFE. Some of these key factors were:

As an expert in health sector sensing, his proposed endeavor is to continue his research on non-invasive sensing approaches that help clinicians better diagnose different conditions to provide better care for pediatric OSA and blepharospasm.
His research endeavor is of great importance because it directly benefits efforts to increase the early detection of diseases. Early disease detection often leads to longer survival for patients and more avenues for the discovery of cures. His advancements in wearable electronic devices offer cutting-edge early detection technology and are crucial for creating easily implementable international screening practices.
His proposed endeavor also has broad implications for the United States where about 3 to 12 percent of American children snore in their sleep and 1 to 10 percent of children suffer from pediatric OSA syndrome.
Due to its clear national importance, his research has in fact been supported with funding from the Defense Threat Reduction Agency (DTRA), the National Institutes of Health (NIH), the Advanced Research Projects Agency-Energy (ARPA-E), the National Science Foundation (NSF), and the Arnold & Mabel Beckman Foundation.
His research has also resulted in 16 peer-reviewed journal articles (4 of them first-authored or co-first-authored) and 1 published patent application publication and these publications have been cited a colossal total of 1,667 times.
Finally, we asked him to get a few letters of recommendation. He got 4 letters supporting the continuation of his work in the U.S.

Not only this but he has been working in the area for 11 years now. This has helped him get the necessary experience to continue his work in the area. We are glad to have been of aid to him in getting his approval and that too by expediting it with the premium processing(PP) upgrade.
