Client’s Testimonial:

“Thanks a lot for your helps.”

On May 15th, 2018, we received another EB-2 NIW (National Interest Waiver) approval for a Postdoctoral Researcher in the Field of Chemical Engineering (Approval Notice).

General Field: Chemical Engineering

Position at the Time of Case Filing: Postdoctoral Researcher

Country of Origin: Taiwan

State of Residence at the Time of Filing: Ohio

Approval Notice Date: May 15th, 2018

Processing Time: 4 months, 23 days

Case Summary:

Less than 5 months after North America Immigration Law Group (NAILG) filed an EB-2 NIW (National Interest Waiver) petition for a Taiwanese postdoctoral researcher, the USCIS sent him notification of case approval. Thanks to the customized NIW petition packet which we had built for our client, he is now one significant step closer to securing a green card.

With ample experience in the field of chemical engineering, a doctoral degree, and various achievements to his name, our client met the NIW requirements set by Matter of Dhanasar (the framework for determining NIW eligibility). Our goal was to convince the USCIS that he deserved the national interest waiver, and we did this by presenting an array of information related to his skills, background, field of expertise, and accomplishments.

For instance, we noted the 87 times his 8 publications were cited along with the 7 times he had assessed the work of his peers. We also paid special attention to his research on chemical catalysis, chemical processes, and materials of industrial and biomedical relevance. We worked diligently to demonstrate that our client’s work radically improves the efficiency of chemical production plants, which by extension means that he is of great value to the chemical industry and thus the U.S.

Besides solid evidence that our client’s work is important to the nation, we incorporated recommendation letters signed by other expert chemical engineers. These letters advocated for the approval of our client’s petition and supported our argument that he should be allowed to continue his research in the country. According to one our client’s recommenders—a prominent professor—he has “a successful career as an innovative researcher.” Another recommender noted that our client is “a leader in his field whose work advances chemical engineering and the related fields in important and unique ways.”

We congratulate our client for securing NIW petition approval and we thank him for trusting us to help him accomplish this goal. We also thank him for retaining our I-485 services to help him and his dependent adjust their status for permanent residence. We guarantee him our continued support and wish him the best as he continues to conduct impactful research in the field of chemical engineering.
