Case Summary:

The team at North America Immigration Law Group (WeGreened.com) maintained its impressive success rate as it helped a postdoctoral research associate in Minnesota secure an I-140 petition. This was followed by the approval of the I-485 applications which we filed for him and his two dependents.

Our client’s groundbreaking studies on the development of biological and chemical sensor systems and nanomaterials have propelled him to the top of his research field. Not just that, his continued presence in the United States immensely benefits the nation as his studies carry many useful applications in areas such as healthcare, food safety, pharmaceuticals, environmental control, and homeland security.

We proved all of this by detailing his outstanding authorship record of 30 peer-reviewed journal articles (14 of them first-authored) and 1 book chapter that had amassed a total of 479 citations from various researchers around the globe. To further strengthen his petition, we urged our client to collect recommendation letters from other experts working in the field of analytical chemistry. We then incorporated these letters into his comprehensive NIW dossier. According to one of these experts, our client has attained “profound knowledge” which is “largely unparalleled in the United States, rendering his presence in the U.S. an indispensable resource.”

Although it took 13 months instead of the expected 4-9 months to receive notification of case approval, NAILG’s scrupulous efforts helped our client secure the national interest waiver. As he chose to file his and his dependents’ I-485 applications while his NIW was pending approval, the USCIS had a head start in processing their applications. Merely 5 months after the NIW was approved, the I-485 applications followed suit. We congratulate our client for obtaining a green card and we wish him the best as he embarks on new beginnings in the United States.
