General Field: Physical Chemistry

Case Summary:

“These innovating technologies by [Client] provide key links to understanding the functioning principles of the brain and to restore the cognitive changes associated with neurodegenerative diseases, which affect millions of Americans every year. Therefore, [Client] is making worthwhile scientific advancements in the field and is contributing immeasurably to the health of the people of the United States”.

The statement above was excerpted from a letter of recommendation that was signed by a highly esteemed professor of chemical biology in support of our client’s EB-1A (Alien of Extraordinary Ability) petition. He was joined by 3 of his peers, all of whom contributed strong recommendation letters supporting the value of our client’s research to the US.

Our client, a postdoctoral research fellow from China, who specializes in the development of flexible electronics devices for a wide range of bioengineering applications, hired our firm to present a convincing EB-1A case to the USCIS. He opted for Premium Processing (PP) and received an approval notice just 9 days later.

Since EB-1A is one of the toughest I-140 categories, we made sure that we thoroughly presented our client’s various achievements in a clear and concise manner. To start with, we pointed out the profound implications of our client’s research. The outcome of several of his notable projects has led to the design of less invasive brain-machine interface technologies and other medically important devices, which positively impacts the medical and healthcare research communities as well as public health in the US. As evidence of his research success, our client’s work has resulted in 16 peer-reviewed scientific articles cited 1,035 times by independent and leading researchers from prestigious institutions and organizations around the world in other peer-reviewed journal articles, along with 20 instances of peer reviews.

In addition to carefully assembling the required documents to file the EB-1A petition on behalf of our client, our team has included customized figures and tables for visualization to indicate that our client’s publications have been cited at a much higher rate than those of other researchers in the field, distinguishing him from his peers. The visual presentation of the data has indeed further constructed and supported the arguments in the petition letter we drafted.

North America Immigration Law Group ( has proudly secured close to 15,000 I-140 approvals over the years, and we are pleased that our client has moved one step closer to his green card success. We thank him for trusting us to help him with his EB-1A petition, and we wish him the very best as he continues to conduct important work in the field of physical chemistry.
