Client’s Testimonial:

“Thank you very much for your support preparing and filing the I140 application. Your diligence and quality of work were outstanding.”

On June 29^th, 2020, we received another NIW (National Interest Waiver) approval for a Senior Petroleum Engineer in the Field of Petroleum Engineering (Approval Notice).

General Field: Petroleum Engineering

Position at the Time of Case Filing: Senior Petroleum Engineer

Country of Origin: Venezuela

State of Residence at the Time of Filing: Texas

Approval Notice Date: June 29^th, 2020

Processing Time: 10 months, 6 days

Case Summary:

This EB-2 NIW (National Interest Waiver) case involved a talented senior petroleum engineer from Venezuela working in the field of petroleum engineering. He hired North America Immigration Law Group (WeGreened.com) to put together a strong NIW case on his behalf.

Support from other experts:

To strengthen our NIW petition, we assisted our client in narrowing down a list of potential recommenders working in the field of petroleum engineering. We selected six experts, all of whom gladly lent their support through recommendation letters. One of these experts wrote, “Given the rising importance of shale production for American energy consumption, the work of [client] is particularly valuable. [Client] provided new insight into the production mechanisms for reservoir rocks with tiny pores. ” These letters served as proof that our client’s insights are essential to the field.

Demonstration of capabilities:

Our legal team amassed a wealth of information on our client’s many professional accomplishments and included them in our well-worded NIW petition packet. We documented our client’s Ph.D. in petroleum engineering, the 48 citations gathered from his 2 peer-reviewed journal articles (1 of them first-authored) and 8 conference papers evaluated and ranked by experts for acceptance in the program (4 of them first-authored), and carefully detailed his research on reservoir simulation and modeling with focus on enhanced oil recovery and integrated production networks. We then used this information to prove to the USCIS that our client’s research in his area is of great importance because it lessens the burden of oil extraction and fossil fuel consumption on the natural environment.

In conclusion:

Thanks to our client’s strong credentials and our legal team’s diligent efforts, the immigration officers at TSC spent about 10 months adjudicating this case. Our client recently retained our I-485 services to propel him to the green card finish line. We look forward to helping him and his spouse attain permanent residency.
