Case Summary:

With a Ph.D. in Petroleum and Geosystems Engineering obtained from a reputable university in the United States, a China-born petroleum engineer hired North America Immigration Law Group (NAILG) to help him obtain a green card. His unique and expansive background of expertise and experience as well as his significant contributions to the field of petroleum engineering made him a good candidate for EB-1A (Alien of Extraordinary Ability). After evaluating his credentials, we were convinced that we could help him get his EB1A petition approved.

The first step was to meticulously present the many benefits of our client’s work to the United States. We did this by collecting information about his citation count, publication record, and peer review experience. The fact that our client’s work had gathered 148 citations at the time of filing and that he had 9 publications to his credit enabled us to prove the value of his work to the immigration authorities. Furthermore, the 50 peer reviews he had conducted reflected his respected status in the field. Additionally, his role as an associate editor for a highly reputable journal unambiguously highlighted the international influence his work had garnered in the field of petroleum engineering.

“[Client] is an inventive and multidisciplinary researcher of the highest caliber. He is nothing but a luminary in the worldwide petroleum industry, and has surpassed the majority of his peers working in the upstream oil and gas industry.” These words of recommendation were contributed by an eminent professor in the field. Our client’s EB-1A case was further strengthened by 5 additional recommendation letters contributed by other petroleum engineering experts.

As he upgraded his case to Premium Processing (PP), our client received notification of case approval just 43 days after filing. This approval bolstered our client’s faith in our law firm and persuaded him to retain us for his I-485 petition. We are happy that we could be of help to our client in pursuing his dream to become a US permanent resident. We congratulate our client and wish him the very best in his future endeavors.
