Success Story: Chinese Postdoctoral Research Associate Earns EB1A Approval After RFE for Pioneering Research in Sustainable Polymer Materials
Client’s Testimonial:
"I rarely endorse others, but choosing Wegreened was one of the wisest decisions I made during my academic journey in the United States. In fact, I even regret not selecting the Wegreened team sooner—I wasted too much time waiting for visa bulletins due to the delayed submission of my National Interest Waiver application (by another attorney before choosing Wegreened). EB1/2 immigration remains a core pathway to U.S. residency, making professional guidance essential. The collaborating attorneys were exceptionally friendly, and the support team was equally so. I am deeply grateful to the Wegreened team for their dedicated efforts in helping me achieve my goals. Furthermore, I strongly recommend that fellow international students and high-tech/education workers planning careers in the U.S. advance planning and select the right immigration visa advisor; we simply don’t have the time to navigate unfamiliar professional fields while also maintaining rigorous academic research commitments. Please plan ahead."
On January 21st, 2025, we received another EB-1A (Alien of Extraordinary Ability) approval for a Postdoctoral Research Associate in the field of Materials Science and Engineering (Approval Notice).
