Success Stories: Thanks to PP, a Sri Lankan Postdoctoral Associate in Advanced Engineering Materials Gets NIW Approval in Just 2 Months and 17 Days
Client’s Testimonial:
“I’m very grateful for the team of Chen Immigration & Attorneys for their excellent help with my I-140! Thank you so much for being patient and providing quick responses to all my questions.”
On February 23rd, 2023, we received another EB-2 NIW (National Interest Waiver) approval for a Postdoctoral Associate in the Field of Advanced Engineering Materials (Approval Notice).
General Field: Advanced Engineering Materials
Position at the Time of Case Filing: Postdoctoral Associate
Country of Origin: Sri Lanka
State of Residence at the Time of Filing: Oklahoma
Approval Notice Date: February 23rd, 2023
Processing Time: 2 months, 17 days (Premium Processing Requested)
Case Summary:
“Luminescence thermometers were already widely used at the time of this project, but [the client’s] confirmation that these materials were viable candidates revealed the functionality of luminescence thermometers in optical thermometry. This has many applications, especially in biosensing activities around the world. [The client’s] work has outlined a method to synthesize and prepare nanocrystals for this far more efficiently than methods commonly used previously. In light of this, [the client’s] cutting-edge developments into improving the processes behind bioimaging techniques stand to benefit the world at large.”
The above passage makes it clear that the client is a talented researcher whose work is of interest to the entire globe. Wanting to file her National Interest Waiver petition, a postdoctoral associate in advanced engineering materials from Sri Lanka approached our firm. As is customary, our team looked into her documents and once they had confirmed her merit, began drafting her petition.
The success of this petition was made possible by the excellent case preparation of our team who used the following data in it:
- As an expert in the field of advanced engineering materials, her proposed endeavor was to continue combining her experience with solution phase synthesis, tailoring composition, structure, and morphology, and evaluating nanomaterials to design guidelines for developing nanoscale films for sensing and energy storage applications.
- Her research advancing her proposed endeavor was of great importance because it contributes to the development of luminescence thermometers and bioimaging techniques.
- Her proposed endeavor also had broad implications for the United States as her work creates advances in the development and fabrication of nanoscale films, which are useful for important applications ranging from optical technology to sensors and energy storage.
- Due to its clear national importance, her research has in fact been supported with funding from the National Science Foundation (NSF). And one of her 4 recommendations had the following to say about her work:
“The U.S. is a global leader in the manufacturing of advanced electronics technology such as these, but international competition in this area is strong and fast-moving. [The client’s] studies on techniques for yielding superior performances with more common material and more straightforward synthesis procedures offer great advantages, and it is to the U.S.’s favor to support her ongoing career.”
- Not only this, but her research has resulted in 8 peer-reviewed journal articles (4 of them first-authored). And these publications have been cited a total of 46 times according to Google Scholar, thereby demonstrating that these publications are widely recognized and relied upon in the field of advanced engineering materials.
- On the other hand, she has also pursued research directly related to her proposed endeavor of designing guidelines for developing nanoscale films for sensing and energy storage applications for 7 years.
Thus, her experience, accomplishments, and recommendations made a great contribution to the success of her case. We are happy to have helped her and to know that the premium processing (PP) upgrade helped her get the approval in just 9 days since the PP request.
