On October 14^th, 2020, we received another O1-A (Individual with extraordinary ability or achievement) approval for a Power System Research Engineer in the Field of Electrical Engineering (Approval Notice).

General Field: Electrical Engineering

Country of Origin: China

State of Residence at the Time of Filing: California

Approval Notice Date: October 14^th, 2020

Case Summary:

A power system research engineer from China hired North America Immigration Law Group (NAILG) to help him file an O-1A (Individuals with Extraordinary Ability or Achievement) petition. 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 12 days (with Premium Processing).

Before we started to 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 Doctor of Philosophy in electrical engineering with a focus on developing innovative solutions to power system vulnerabilities and cyberattacks along with related technical challenges in electrical engineering. His research addresses some of our nation’s most pressing issues in understanding the best methods for cyber security and power system reliability. His winning O-1A petition packet also included:

Original contributions: At the time of filing, our client had already been cited 689 times. This proved the value of his work not just to other researchers but to the field of electrical engineering as a whole.
Authorship: The many years that our client has dedicated to the field have resulted in 50 peer-reviewed scientific articles, all of which were published in well-known scientific journals.
Judge of others’ work: To highlight the fact that our client’s ideas and opinions are respected by other researchers in the field, we presented his peer review record- 330 reviews conducted by the time we filed his case.

To validate the extent of international influence his work had garnered, our client procured four written advisory opinions signed by top-level experts. One of the recommenders stated: “... [Client] is one of the advanced individuals conducting research in this area today, and the field’s continued improvement depends heavily upon his ongoing contributions to this research area.”

We are pleased that our hard work paid off and we successfully demonstrated that our client had satisfied the O1A criteria. We congratulate him for securing O1-A petition approval and we thank him for trusting our law firm to be a part of his success story.
