Case Summary:

With a Ph.D. in petroleum engineering, our client displays the knowledge and experience to advance his research in petroleum engineering. When he communicated with North America Immigration Law Group for supporting him to log an I-140 NIW (National Interest Waiver) petition on his account, we started evaluating his academic and research practice background. We discovered that his research is to develop advanced rock and fluid simulation models and tools using petroleum engineering techniques and numerical methods to enhance oil recovery and maximize production in oil and gas fields.

Our goal was to prove to the USCIS that our client’s research has great importance because it provides efficient means to extract oil and gas from underground. His research in this area is key to driving economic growth in the United States’ oil and gas industries, which are currently the world’s most important sources of energy. Therefore, we highlighted the required information, strengthening our client’s case:

We emphasized his publications including 8 peer-reviewed journal articles, and 11 conference proceedings (5 of them first-authored), and these had altogether gathered 266 citations, symbolizing that his publications are well-acknowledged in the field of petroleum engineering.
Further, our client is an effective peer reviewer for distinguished journals, and he has conducted 60 reviews. Only notable experts in their field are requested to perform extensive review work, demonstrating his significant standing in the field.
To impel the petition forward, we added recommendation letters collected by our client from two well-recognized experts in the field, providing further acumen into the merit of his attempt.

We were successful in persuading the USCIS that our client’s research work has a great involvement for the United States as the nation’s most prevalent energy source, oil is vital to securing the United States’ economic and security interests. Our client got this approval after thorough consideration, and we congratulate him as he continues advancing in this field.
