Success Stories: Research Associate in the Field of Microbiology with Only 3 Citations Receives Green Card


Client’s Testimonial:

“Thank you. I also received approval of my I-140 in the mail.”

On March 11th, 2016, we received another EB-2 NIW (National Interest Waiver) approval for a Research Associate in the Field of Microbiology (Approval Notice).


General Field: Microbiology

Position at the Time of Case Filing: Research Associate

Country of Origin: Nigeria

Service Center: Texas Service Center (TSC)

State of Residence at the Time of Filing: Texas

Approval Notice Date: March 11th, 2016

Processing Time: 10 months, 17 days

Case Summary:

With an M.Sc. in Health Promotion and Public Health and many years of experience working in the field of microbiology, our client (a research associate from Nigeria) qualified to file her I-140 petition under the EB-2 NIW (National Interest Waiver) visa category. North America Immigration Law Group ( helped her put together a strong petition packet that ultimately convinced the USCIS to approve her NIW petition. Because our client opted to file her I-485 application (final step in green card proceedings) while her petition was pending approval, she received a green card approval a month after she received her NIW approval.

EB-2 NIW Petition Packet:

When we filed her case, our client’s 2 publications had collected 3 citations. This proved the value of her work to other researchers in the field of microbiology where the amount of scholarship activity is relatively low. With a focus on biocorrosion, or the involvement of microorganisms in the corrosion process, our client’s work is essential to countries like the United States, where corrosion contributes to high industry expenditure, and maintaining low environmental impact is a major concern. We demonstrated that not only is our client an asset to the nation, but that only a handful of other researchers with similar qualifications can mirror her research success.

Third-Party Support:

To further strengthen our NIW presentation, we prompted our client to touch base with other influential researchers in her field. We needed her to persuade them to contribute recommendation letters supporting our claim that she should continue her research in the United States. Our client did not disappoint, and returned with six strong testimonials, one of which described her work as beneficial to the petroleum industry: “I must also stress that her work have public health and environmental benefits. Chemical leakages due to corroded pipelines and drilling gear are a public health hazard, and have been documented in the Permian Basin to have contaminated tap water sources. The reduction of corrosion decreases the incidence of chemical leakages, allowing water quality to improve.”

Agreeable Results:

From the date we submitted our client’s EB-2 NIW petition to the date she received her green card, our client patiently waited close to a year (her I-485 application was filed while her I-140 petition was pending approval). We congratulate our client and her partner for becoming American permanent residents, and we wish her well as she continues to investigate the field of microbiology.
