Case Summary:

An assistant professor with a Ph.D. in electrical and computer engineering approached North America Immigration Law Group to obtain an O1-A (Individuals with Extraordinary Ability or Achievement) visa. She necessitated our support in logging an I-129 petition on her behalf, exhibiting her as an individual with extraordinary ability to advance her work here in the United States. With our many years of experience dealing with employment-based visa petitions, we began filing her O1A petition leading her to approval.

We aimed to validate the importance of our client’s research to the USCIS. We thoroughly assessed her research focusing on developing advanced power grid control and monitoring methods to optimize renewable energy resource integration while maintaining overall system reliability. After reviewing, we reasoned that our client’s research directly addresses critical issues related to improving the implementation of renewable energy sources in the U.S. power grid. Her many years of experience as well as her leadership and expertise in the field have therefore established eligibility for her petition to be approved.

Additionally, we noted her citation and publication record, including 24 peer-reviewed scientific articles (16 of them first-authored), 1 book chapter, and 1 technical report that had amassed 303 citations from other superior researchers in the field. Her research work has also been featured in several notable publications, which have certainly attracted the attention and acclaim of both researchers in the field and the U.S. government, thereby demonstrating its numerous benefits. Moreover, at the time of filing, she had already reviewed 50 articles for highly acclaimed journals, signifying her as very knowledgeable in the field and an expert in topics related to her proposed endeavor.

Towards the submission of her petition, we added four recommendation letters obtained from other expert professors in the field, further corroborating that throughout her time working in the field, she had an impressive record of success. According to one of the independent advisors:

“[Client] has developed novel modeling approaches for quickly estimating renewable energy resource penetration limits, which is especially important in cases where power grids do not have robust regulation capabilities. As a result, her work directly contributes to increasing renewable energy utilization around the world.”

The USCIS spent 18 days adjudicating our client’s case and granted her the O1-A approval, thanks to premium processing and our dedication towards getting her the approval. We had a pleasure working with her and congratulate her on this turning point.
