General Field: Materials Science

Position at the Time of Case Filing: Assistant Professor

Approval Notice Date: November 5th, 2020

Processing Time: 2 months and 24 days (Premium Processing Requested)

Case Summary:

An assistant professor from Peru hired North America Immigration Law Group (NAILG) to help him obtain an O1-A (Individuals with Extraordinary Ability or Achievement) visa. In order to receive notification of case approval, he needed to show that he was an individual with extraordinary ability who was temporarily entering the United States to continue work in his area of specialization. With our help, our client accomplished this goal and received petition approval in just 2 months and 24 days. Our vast experience dealing with employment-based visa petitions armed us with the perfect legal strategy to secure our client’s O1A petition approval.

Before we started work on the case, we conducted a thorough evaluation of our client’s credentials to verify his chances of O1-A approval. We confirmed that he held a doctoral degree in chemical physics with a focus on the use of ferroelectric, magnetic and multiferroic materials in resistive random-access memory (ReRAM). We successfully determined that our client’s research addresses some of our nation’s most pressing issues in understanding how to create next-generation memory devices and neuromorphic computing devices. Our goal was to prove to the USCIS that our client’s findings are of great importance to the United States.

Our client’s O1A petition packet also detailed his citation and publication record. At the time of filing, our client’s publications included 24 peer-reviewed scientific articles that had accumulated 379 citations. Moreover, our client has reviewed 29 articles related to the field of materials science. Only top-level experts in their field are invited to perform this type of important editorial work, so this frequent activity further demonstrates our client’s important standing in the field.

To validate the extent of international influence his work had garnered, our client procured four letters of recommendation signed by top-level experts. These letters, which were incorporated into our client’s O1-A petition dossier, amply endorsed his credentials.

After months of diligent work, we successfully demonstrated that our client had satisfied the O1A criteria. We congratulate him for securing O1-A petition approval and we also thank him for trusting our law firm for his NIW application.
