Case Summary:

The many years that our client has spent conducting research in the field of theoretical nuclear physics has led to numerous achievements, several of which were detailed in his EB-1A (Alien of Extraordinary Ability) petition. For instance, his peer review record (27 reviews conducted for a variety of scientific journals) and the whopping 1,610 citations gathered from his 86 scientific articles were highlighted. Despite his strong credentials, he needed North America Immigration Law Group ( to persuade the USCIS that he is an extraordinary researcher and that his work is of great importance to the United States.

Besides our client’s citation count, publications record, and peer review experience, we also detailed his work on the microscopic study of nuclear structure, reactions, and fundamental problems. After carefully reviewing and understanding his research, we determined that his work addresses some of our nation’s most pressing issues by understanding the important problems in nuclear and particle physics and providing theoretical explanations and predictions to support further experimental investigations throughout the field.

An important element of our client’s EB1A petition had to do with the 5 recommendation letters contributed by other expert physicists. These letters demonstrated the value of our client’s continued research in the field and strongly advocated for the approval of his EB1A. According to one of them: “… [Client’s] work is instrumental to ongoing progress in theoretical nuclear physics and that any interruption of his efforts would be detrimental to our field. His continuing efforts are particularly beneficial to theoretical physics within the U.S…”

As our client opted to pay an additional $1,225 to the USCIS to have his petition filed under Premium Processing (PP), he received notification of case approval exactly 13 days after filing. We congratulate him for securing petition approval, and we wish him the best with the I-485 application.
