On May 6th, 2013, we received another EB2 NIW (National Interest Waiver) Approval for a Postdoctoral Researcher in the field of Biochemistry and Biotechnology (Approval Notice)

General Field: Biochemistry and Biotechnology Position at the Time of Case Filing: Postdoctoral Researcher National Origin: China Service Center: Texas Service Center (TSC) State Residing at the Time of Filing: Louisiana Approval Notice Date: May 6, 2013 Processing Time: 1 month

Case Summary:

The average processing time for I-140 cases is 4-6 months. But on many occasions, we have cases approved far faster than the average processing time.

This client is a Postdoctoral Researcher from China in the field of biochemistry and biotechnology. Her work has specifically focused on developing ways to create or improve treatments at the molecular level for a number of diseases and conditions, ranging from hypertension to the West Nile Virus. In order to ensure the success of this case, we submitted extensive documentation of the client’s highly significant contributions to the field of biochemistry and biotechnology, including her authorship of seven peer-reviewed journal articles, which garnered scores of citations, and two patents. Additionally, our firm drafted and submitted several recommendation letters from experts in our client’s shared field. One of the independent recommenders noted, “Besides the obvious medical benefits of [the Petitioner’s] work, she has also made contributions that help to fill in knowledge gaps within the field. She has shown that antibody glycosylation patterns can alter the quality of the antibody’s ability to treat disease. She has harnessed recent progress in plant glyco-engineering that allows the creation of transgenic plant lines that produce MAbs with uniform mammalian N-linked glycans, to make glycan-defined antibodies to create safer and more effective clinical reagents for WNV, while also increasing field understanding of how differences in carbohydrates on IgG modulate effector function.” With the strong petition letter and recommendation letters we prepared, her NIW case was approved in just one month.
