We had a client with experience researching West Nile Virus, who wished to gain permanent residence on that basis. However, he was only at the postdoctoral stage of his career and did not have an offer of a tenure-track or full-time research position. When we noted that his record contained publications in some of the most widely-read journals in science, we filed a National Waiver Interest (NIW) case on his behalf. The USCIS agreed that this showed impact on the field as a whole, and his case was approved.
