General Field: Stem Cell Biology

Position at the Time of Case Filing: Ph.D. Student

Country of Origin: Germany

State of Residence at the Time of Filing: California

Approval Notice Date: December 5th, 2019

Processing Time: 6 months, 2 days

Case Summary:

A Ph.D. student hired North America Immigration Law Group ( to file an EB-2 NIW (National Interest Waiver) petition on his behalf. With a M.Sc. in medicine and extensive experience researching the field of stem cell biology, our client was suitably qualified for this visa category.

What does it take to build a Strong NIW case?

For one, we documented our client’s impressive citation count (440 citations at the time of filing) as well as his publication record of (4 peer-reviewed journal articles and 1 first-authored book chapter). We also reviewed his research summary and demonstrated to the USCIS that he is focused on gene expression and regulation in stem cells. His research in this area is of great importance because he proposes effective ways to reprogram cells to regenerate tissues, and has developed new tools to identify stem cells to improve cancer therapy, which is certainly of global need, as the worldwide burden of cancer of cancer is expected to grow to 27.5 million new cancer cases each year as the proportion of the global elderly population grows.

In addition to that, our client’s winning EB-2 NIW petition packet contained 4 recommendation letters that strongly advocated for the approval of his case. These letters were contributed by experts working in the field, one of whom described our client as: “[Client’s] work also benefits the United States specifically. His studies in stem cell biology support the most foundational aspects of regenerative medicine, enabling American doctors to more effectively reprogram cells to heal damaged tissue. This is one of the most important issues in overcoming diseases like cancer, which affects countless Americans and becomes more prominent each year. The United States therefore stands to gain enormously from [Client’s] work, […], [Our Client] is ideally placed to provide the United States with the full benefits of his talent.”

Our client received his approval notification exactly 6 months and 2 days after filing. To obtain a green card, our client has to adjust his status for permanent residency by filing an I-485 application. We shared our complimentary D.I.Y Packet to help him with this, and we wish him the best with the final step in the green card process. In conclusion, we would like to thank our client for believing in our services and we wish him a bright future here in the United States.
