Case Summary:

A Postdoctoral Associate from China hired North America Immigration Law Group ( to file an EB-1A (Aliens of Extraordinary Ability) petition on his behalf. With a PhD in chemical engineering, our client boasts extensive experience in the study of advanced electrochemical energy storage systems. His specialized research on interfacial phenomena of lithium-ion batteries and the development of functional solid polymer electrolytes contributes to the improvement of performance and safety of energy storage units. Our client’s EB-1A was approved in only 12 days thanks to the combination of Premium Processing (PP), our client’s strong qualification, and our team’s meticulous case preparation efforts.

Through fundamental and applied research, our client enables the development and application of solutions for clean energy and global security; in fact, the importance of his findings influences not only the engineering field but the environmental, agricultural, and biomedical field. These contributions have proven to be highly advantageous to his peers. In evidence of this, we noted the 25 peer-reviewed journal articles and 1 patent he has published, and the 247 citations he has received, offering proof of the significance of his work across the field, and that others in the field have come to rely heavily on his research works. In addition, our client has also conducted 17 reviews for multiple highly distinguished journals. This frequent participation in the editorial processes of numerous academic journals also indicated his established position as a leading expert in chemical engineering.

Alongside the aforementioned information were letters of recommendation. To support our argument that our client is one of a small handful of experts who have risen to the top of the field, we included 6 letters signed by other chemical engineering experts and incorporated them into his petition. These letters, such as the one mentioned below, made some very cogent testimonials regarding his various achievements and ways in which they benefit the country: “Few scientists working in this field approach the level of accomplishment achieved by [Client], and so I am confident in asserting that he is performing at the top of his field”.

We congratulate our client for coming this far in the green card journey, and we thank him for choosing to work with us.
