General Field: Chemical Engineering

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

Country of Origin: Iran

State of Residence at the Time of Filing: Alabama

Approval Notice Date: January 23rd, 2020

Processing Time: 5 months, 25 days

Case Summary:

As an expert in the field of chemical engineering, our client’s research focuses on engineering human tissue models for anticancer drug testing. His research in this area is of great importance because it is relevant to the development of improved cancer cell cultures for in vitro drug testing. We worked with our client carefully and presented his various achievements to the USCIS in a clear and concise manner.

Apart from completing successful research in the field, our client has also published 3 peer-reviewed journal articles that collected 60 citations by the time when we were ready to file his case. He has also conducted a review for a distinguished journal. The fact that his papers being published in the top journals and that his peers leveraged his research demonstrated that our client’s work is widely recognized and relied upon in his field. We incorporated the related material into our client’s petition letter, and provided in-depth analysis to show the merit of his endeavor.

Alongside the aforementioned information, we included 5 letters of recommendation signed by other influential researchers. These letters fully corroborate the independent and objective evidence that demonstrate our client’s original contributions. According to one of these recommenders: “[Client’s] work in this area is vital given the shortcomings of conventional models for studying breast cancer and other forms of cancer. Extant approaches are particularly ineffective when it comes to investigating metastasis, which is linked to approximately 9 out of 10 cancer-related fatalities. [Client] has appreciably advanced the state of scientific research into the tumor microenvironment, supporting his status as a renowned figure in the field.”

We are glad that our hard work paid off and his case was approved in less than 6 months. We thank our client for choosing us for his NIW case and to be a part of his success.
