Client’s Testimonial:

“Thank you so much.”

On April 25th, 2022, we received another EB-2 NIW (National Interest Waiver) approval for a Researcher in the Field of Economics (Approval Notice).

General Field: Economics

Position at the Time of Case Filing: Researcher

Country of Origin: Nigeria

State of Residence at the Time of Filing: Kansas

Approval Notice Date: April 25th, 2022

Processing Time: 4 months, 22 days

Case Summary:

The I-140 NIW (National Interest Waiver) is a highly specific type of nonimmigrant visa for those foreign nationals who can prove that they hold enough value for the United States to get a labor certification waiver. This is where our firm comes in and helps the applicants in filing the best petition letter they can to win the NIW approval from the USCIS. So, when we got a client from Nigeria willing to apply for the NIW, we made sure to use the following information in his petition:

  • As an expert in the field of economics, his proposed endeavor is to continue developing AI models that can predict energy prices and demand, analyze the impact of energy deregulation on economic growth, and forecast the welfare benefits of renewable energy, including business cycle forecasting, the effects of asymmetric monetary policy on housing, and household consumption growth.
  • His research is relevant to renewable energy in the U.S. The enforcement of green energy policy and carbon emission, electricity price variability from renewable energy intermittency and renewable energy installed capacity.
  • His research advancing his proposed endeavor is also of great importance because climate change has far-reaching global economic effects.
  • He has completed at least 2 reviews to date, and his research has resulted in 8 peer-reviewed journal articles (1 of them first-authored) which have been cited a total of 25 times according to Google Scholar.

Armed with 2 letters of recommendation from other experts in the field, his application was a strong one and won approval from the adjudication committee in just 4 months and 22 days, and that too without RFE. We are glad to have been of help to him, and we wish him all the best.
