Case Summary:

With an impressive track record in the field of analytical chemistry as well as a doctoral degree, our client (a postdoctoral fellow from Sri Lanka) was a suitable candidate for the EB-2 NIW (National Interest Waiver) visa category. After evaluating his credentials, we were convinced that we could build a watertight case for him by highlighting his laudable accomplishments.

Our Services:

The comprehensive NIW dossier we prepared contained proof of our client’s praiseworthy achievements. We noted the 292 times his work had been cited by his peers and the 18 peer-reviewed journal articles he had under his authorship. Moreover, his work on interfacial phenomena in nanomaterials and nanomaterial catalysis was particularly commendable since it helps improve the United States’ energy independence and industrial productivity, specifically aiding the development of catalysis and biomedical engineering.

Of major importance were the 4 recommendation letters that were signed by our client’s peers. One of them stated: “Considering what he has accomplished thus far, it is clear that [Client] is one of the foremost researchers in analytical chemistry and possesses qualifications far above those of most of his competitors. As a result, we should make his continued work in the United States a priority.” These letters of recommendation proved to the USCIS that our client’s continued presence in the US would be a boon to the country’s scientific community.

New Beginnings in the United States:

We are pleased that our hard work paid off and that our client secured an NIW petition approval. As he opted to concurrently file his I-140 and I-485 application (the two steps in the green card process), he realized his dream of obtaining a green card considerably quicker than the norm. From start to end, our client waited less than 8 months to receive his green card. We join him as he celebrates this joyous occasion, and we thank him for working with North America Immigration Law Group (
