Case Summary:

Nearly 10 months after North America Immigration Law Group ( filed an EB-2 NIW (National Interest Waiver) petition for a Vietnamese postdoctoral research associate, the USCIS approved his case. Despite the lengthy wait, our client is now one big step closer to a green card, and we are pleased that we helped him overcome the I-140 hurdle.

When our client first approached us, we carefully reviewed his credentials to be sure that he qualified for the national interest waiver. Once we determined that we could build a strong NIW case for him, we countersigned the retainer agreement and gathered a wealth of information related to his studies in the field of materials science.

As part of our comprehensive services, we helped our client narrow down a list of expert materials scientists who could potentially serve as recommenders. We made sure that these recommenders were familiar with our client’s publications (13 peer-reviewed journal articles as well as 2 conference proceedings articles) and/or had worked with him. Not long after we supplied our client with the list, he returned with six signed letters, one of which contained this strong statement: “[Client’s] research achievements are unquestionably the work of a scientist at the very peak of his field. Not many scientists could hope to match his accomplishments in developing new materials for technology, and his achievements so far point to even more breakthroughs in the future.”

Alongside the aforementioned letters were details on the 68 times our client’s work was cited, his CV, doctoral degree, evidence regarding his current employment, and other supporting evidence to prove that he is an asset to the United States.

We are pleased that our hard work paid off and that our client obtained NIW petition approval. We congratulate him on this win and thank him for choosing us to represent his case.
