“Thank you again for your very professional help with my O1A.”

On January 21^st, 2022, we received another O1-A (Individuals with Extraordinary Ability or Achievement) approval for a Senior Technical Staff in the Field of Wireless Communications (Approval Notice).

General Field: Wireless Communications

Position at the Time of Case Filing: Senior Technical Staff

Country of Origin: Russia

State of Residence at the Time of Filing: Virginia

Approval Notice Date: January 21^st, 2022

Case Summary:

Gladly, we succeeded once again in demonstrating a senior technical staff’s research’s great importance because it contributes to the development of novel technologies related to network automation, energy efficiency, spectrum efficiency, mobile and wireless communications, Wi-Fi networks, and other aspects of modern-day communications. Thanks to our team’s perseverance in this case as well as the Premium Processing upgrade, helped our client in attaining the O1A approval in just 25 days rather than waiting for 11 to 12 months.

Armed with a Ph.D. degree in telecommunication systems, networks, and devices, our client hired North America Immigration Law Group to help him secure an I-129 O1-A (Individuals with Extraordinary Ability or Achievement) visa approval. Before taking his case, we thoroughly reviewed his credentials. It was noteworthy to explore that he intended to improve and develop technologies for network automation, such as self-organizing networks, artificial intelligence, and machine learning, to optimize the performance of 5G/6G wireless networks and improve energy efficiency, spectrum efficiency, availability, and user’s quality of experience. He certainly exhibited exceptional abilities to acquire the O1A success. Thus, we were determined to support him entirely in establishing the substantial merit and national importance of his research to the USCIS.

We started off by noting his citation and publication record, including 53 peer-reviewed scientific articles, 2 book chapters, and 8 patents, which altogether assembled 1,401 citations, confirming that his research is a significant representation in the field which is incredibly enlightening.

Similarly, he had conducted 65 peer reviews for highly acclaimed journals, confirming that he is also an active member of the scientific community. Viewing that only top-notch experts in their field are encouraged to perform this important review work, apparently, his regular invites for the review activity show that he is considered a leader in the field of wireless communications.

To boot, we included four recommendation letters acquired by our client from fellow scientists in the field, corroborating how our client has developed algorithms and protocols for supporting dynamic networks and has established that he is vitally important to the wireless communications field.

Therefore, we were finally able to affirm to the USCIS that our client’s continued investigations within the United States remain highly desirable. Also, we thank our client for having faith in our law firm to represent his O1A case and for allowing us to be an integral part of this remarkable success story.
