Success Stories: Our Firm Helped a Postdoctoral Researcher From China to Secure NIW approval in 6 Months


Client’s Testimonial:

“I appreciate all your help during the preparation of this application.”

On March 20th, 2020, we received another NIW (National Interest Waiver) approval for a Postdoctoral Researcher in the Field of Electrical Engineering (Approval Notice).

General Field: Electrical Engineering

Position at the Time of Case Filing: Postdoctoral Researcher

Country of Origin: China

State of Residence at the Time of Filing: Wisconsin

Approval Notice Date: March 20th, 2020

Processing Time: 6 months, 10 days

Case Summary:

A postdoctoral researcher engaged the legal services of North America Immigration Law Group ( for help with his I-140 petition (first step in the green card process). After thoroughly going through his credentials, we verified that the best course of action to get a green card would be to file his I-140 petition under EB-2 NIW (National Interest Waiver). As soon as an attorney-client relationship arose, we immediately set out to prove to the USCIS that our client’s research is important to the United States and that not many other researchers can mirror his success.

Steps Leading Up to Petition Approval:

As strong as our client’s credentials were, and as skilled as our legal team was at putting together successful EB-2 NIW petitions, it did not change the fact that gaining petition approval was a challenging task. We started off by asking our client to gather recommendation letters from other researchers in his field. The handful of letters that he managed to obtain were strong and certainly served their purpose of proving to the USCIS that our client’s work positively impacts the nation. For instance, one of the letters stated that: “In critical military operations, downtime is not acceptable, so it is imperative that the vehicles operated by personnel remain in working order. In this case, [client’s] development is quite beneficial. Although this is only one example, it serves to demonstrate the importance of [client’s] research.”

These recommendation letters were accompanied by summaries of our client’s portfolio: his citation count, publication record, and research projects. When we filed the case, our client’s work on creating innovative designs of electric machines and high-performance drives for transportation electrification had amassed 218 citations, and he had published 36 peer-reviewed journal and conference articles (12 of them first-authored) and 6 Chinese patents. He had also conducted 55 peer reviews for various scientific journals. We used these accomplishments and other evidence that we had collected to firmly establish that our client’s investigations are essential to the United States. In addition, his work has benefits for numerous impactful industries, particularly the aerospace industry.

In Conclusion:

The USCIS spent 6 months and 10 days reviewing this NIW case before granting the approval. We are pleased at the outcome and would like to thank our client for placing his trust in us. We congratulate our client for overcoming this hurdle and wish him the best as he continues to advance the field of electrical engineering with his extensive research.
