Case Summary:

North America Immigration Law Group was contacted by a material scientist to document an O1-A (Individuals with Extraordinary Ability or Achievement) petition on his behalf.

Our goal was to authenticate that he was an individual with extraordinary ability to continue his research work here in the United States. Our client was aware of our expertise in dealing with the O1-A visa category. Thus, we began building his case and verified that our client’s publications included 7 peer-reviewed scientific articles, 1 book chapter, and at least 1 patent that had accumulated 34 citations. Additionally, our client has conducted 13 reviews for highly acclaimed journals in the field of materials science, signifying that our client is considered to be one of the well-knowledgeable experts in their field.

Moreover, we outlined to the USCIS that our client held a Ph.D. in manufacturing engineering and conducting his research on examining the process-microstructural-properties of various materials by developing new manufacturing processes based on solid and advanced knowledge of metallurgy and materials science. His research addresses some of our nation’s most pressing issues in understanding how to develop manufacturing processes for new materials to upgrade and improve their performance for a range of applications.

To confirm the importance of his research further in the United States, we incorporated 5 recommendation letters from other experts in the field testifying to the benefits of our client’s work which continue to impact all parts of the nation by providing a foundation for further developments in materials science. One of his recommenders deduced:

“[Our client] is an expert scientist in the field of materials science whose forward-thinking research on improving the mechanical properties of aluminum alloy has provided new progress toward the development of stronger, more cost-effective aluminum alloy systems. His continued work in the United States is thus critical to the advancement of the field.”

We were capable of demonstrating our client’s case to the USCIS and how it satisfied the O1A requirements. Thanks to our efficient legal team and premium processing service, he obtained the O1-A petition approval in just 8 days. We would like to thank him for choosing us to represent his O1-A application.
