Case Summary:


“[Client’s] career has far exceeded any reasonable expectations for a physicist specializing in optical properties and plasmonics, and his consistently original research marks him as a pioneer in the field.”

This statement was made by a prominent assistant professor working in the field of physics. She, and several other experts, endorsed our client’s EB-1A (Alien of Extraordinary Ability) case by volunteering recommendation letters that verified the significance of his research to not just the field of optical physics, but to the United States as a whole.

Our client, a postdoctoral research associate from China, is studying the optical properties of various nanomaterials. His projects have led to the design of a transparency window mechanism, the development of effective methods for tuning plasmon resonance, and the proposal of theories for hot electron generation in nanoparticles and the enhancement of the circular dichroism signal. Our legal team prepared an airtight EB-1A petition that documented our client’s 30 publications, the 529 citations his work had amassed at the time of filing, and his impressive peer review experience.

Our client elected to file his case under Premium Processing, which essentially shortened the wait time for a decision. The USCIS granted their approval 10 days after we filed the case on his behalf. We congratulate our client on this occasion and wish him the best in hastening progress within his field of optical physics.
