Success Stories: With our help, a Postdoctoral Research Associate in the Field of Materials Science Secures an NIW Petition Approval, Despite RFE


Client’s Testimonial:

“So thank you so much for your excellent efforts! Great job for everyone! We are extremely happy!”

On January 28th, 2020, we received another NIW (National Interest Waiver) approval for a Postdoctoral Fellow in the Field of Materials Science (Approval Notice).

General Field: Materials Science

Position at the Time of Case Filing: Postdoctoral Fellow

Country of Origin: Thailand

State of Residence at the Time of Filing: Georgia

Approval Notice Date: January 28th, 2020

Processing Time: 10 months, 21 days

Case Summary:

A postdoctoral research associate hired North America Immigration Law Group ( to file an EB-2 NIW (National Interest Waiver) petition on his behalf. With a Ph.D. in materials science and engineering and extensive experience researching the same field, our client was suitably qualified for this visa category.

What does it take to build a Strong NIW case?

For one, we documented our client’s impressive citation count (54 citations at the time of filing) as well as his publication record of 9 peer-reviewed journal articles (6 of them first-authored). We also reviewed his research summary and demonstrated to the USCIS that he is focused on the design and characterization of advanced materials for energy and pharmaceutical applications. His research in this area is of great importance because it contributes to protecting the global environment and promoting advancement in medicine.

In addition to that, our client’s winning EB-2 NIW petition packet contained 6 recommendation letters that strongly advocated for the approval of his case. These letters were contributed by experts working in the field, one of whom described our client as: “… [client] has also worked with novel materials for gas separation, a process with clear-cut value in the development of sustainable energy technologies and, therefore, the energy independence efforts of the United States. It is quite apparent to me that permitting [client] to further his research here indefinitely will continue to benefit the country as a whole.”

Request for Evidence (RFE):

Despite our meticulous presentation of our client’s strong credentials, the USCIS issued a Request for Evidence (RFE). As soon as we received the RFE, our legal team sprang into action. We promptly responded to the RFE and successfully dealt with all hesitations about our client’s qualifications.

EB-2 NIW approval:

Overall, it was 10 months and 21 days before the USCIS approved our client’s EB-2 NIW case, and we are pleased that they ultimately granted approval. We congratulate our client on this milestone and thank him for also choosing us for his I-485 applications.
