Success Story: NIW Approval Without RFE for a Graduate Teaching Assistant
Client’s Testimonial:
"I liked to work with them. They are super sincere about all things related to case filing. They scrutinize every single detail of clients. I highly recommend this law firm.”
On March 30th, 2026, we received another EB-2 NIW (National Interest Waiver) approval for a Graduate Teaching Assistant in the Field of Biology & Bioinformatics (Approval Notice).
General Field: Biology & Bioinformatics
Position at the Time of Case Filing: Graduate Teaching Assistant
Approval Notice Date: March 30th, 2026
Processing Time: 15 months, 11 days
Case Summary:
With an M.S. in biology, this graduate teaching assistant built a strong case for I-140 NIW approval through work focused on understanding how bacterial and parasitic pathogens cause disease in mammals and birds. The proposed endeavor involves analyzing the genomic sequences of bacteria, cestodes, and tick parasites to identify evolutionary lineages and gain insights into disease mechanisms. The ultimate goal of this research is to advance microbiology and parasitology, thereby improving public health through disease prevention and environmental conservation. At the time of filing, this research was actively being conducted at a U.S. institution, demonstrating both continued engagement in the field and clear positioning to carry the proposed endeavor forward.
Establishing a Strong Scientific Record
The research record included 4 peer-reviewed journal articles, 2 first-authored conference abstracts, and 1 preprint, with 107 citations to published work. These publications appeared in highly regarded journals in the field, reflecting meaningful recognition from the broader research community. Funding from the Tertiary Education Trust Fund further corroborated the external recognition of the work's value.
Demonstrating National Importance Through Infectious Disease Research
North America Immigration Law Group (Chen Immigration Law Associates) emphasized that this body of research carried significance well beyond academic publication. Tick-borne diseases have more than doubled in prevalence in the United States over the past two decades, representing a serious and growing public health challenge. The petition framed the genomic and parasitological research as directly relevant to improved disease surveillance, targeted prevention strategies, and the reduction of zoonotic disease risk. The work was also connected to investigations into probiotic alternatives to antibiotics, addressing the national priority of combating antimicrobial resistance.
Expert Endorsement
The petition was supported by two recommendation letters from experts at U.S. and international institutions. One recommender noted:
"[Client's] research holds value for improving public health outcomes and lowering the prevalence of foodborne illnesses by identifying the traits of these robust strains."
A Positive Outcome
This I-140 NIW approval without an RFE demonstrates how a well-defined proposed endeavor, supported by a focused publication record and carefully contextualized citation evidence, can form a persuasive national interest case. We are proud that our firm had the opportunity to assist in presenting this case successfully.
