A recent client of ours was a synthetic organic chemist with a strong patent and publication record.  He therefore had an approvable EB-2/National Interest Waiver case, which requires documented impact in the field. A nice feature of this category is that it allows for self-sponsorship, so no offer of employment is necessary.  However, the individual must be able to show continuing activity in his or her field. After putting in some extra effort to demonstrate our client‘s situation did meet all requirements for the category, we received word that his NIW case had been approved.  We were happy to be of service to a talented chemist, and to the prestigious university department where he does research.
