Success Stories: With our Help, a Postdoctoral Research Associate from Taiwan Secured NIW Approval Without RFE and Now Filed I-485
Client’s Testimonial:
"It is a great experience to work with Chen Immigration. The attorneys are responsible for my case and doing things carefully. Thanks a lot for the help!!”
On March 31st, 2020, we received another NIW (National Interest Waiver) approval for a Postdoctoral Research Associate in the Field of Materials Science (Approval Notice).
General Field: Materials Science
Position at the Time of Case Filing: Postdoctoral Research Associate
Country of Origin: Taiwan
State of Residence at the Time of Filing: Connecticut
Approval Notice Date: March 31st, 2020
Processing Time: 10 months, 21 days
Case Summary:
A postdoctoral research associate hired North America Immigration Law Group (NAILG) to file an EB-2 NIW (National Interest Waiver) petition on his behalf. With a Ph.D. in agricultural chemistry and extensive experience researching the field of materials science, our client was suitably qualified for this visa category.
What does it take to build a strong NIW case?
- We documented our client’s citation count (43 citations at the time of filing) as well as his publication record (8 peer-reviewed journal articles). We also reviewed his research summary and demonstrated to the USCIS that his work is focused on the structural characterization of various materials used in drug delivery systems and other important applications, including self-assembled supramolecules, biomaterials, and mechanofluorochromic materials. His research in his area is of great importance because it contributes to the development, evaluation, and optimization of various materials and molecules that are widely used throughout the field to achieve desired research results and improve public healthcare initiatives.
- In addition to that, our client’s winning EB-2 NIW petition dossier contained six recommendation letters that strongly advocated for the approval of his case. These letters were contributed by other experts working in the field of materials science, one of whom described our client and his work as: “[Client’s] remarkable skills as an investigative researcher have enabled him to ascend to the top of his field, where his efforts have consistently provided the missing links needed to advance our knowledge and design better functional materials in the United States.”
The USCIS spent 10 months and 21 days adjudicating our client’s EB-2 NIW petition before granting their approval. Not long after he received notification of case approval, our client retained our I-485 services to help him and his spouse adjust their status for permanent residence. We thank them for working with us and look forward to helping them obtain their green cards.
