Case Summary:

“The importance of [client’s] research innovations combined with his strong theoretical comprehension, notable technical abilities, and influence on the research of his peers represent extraordinary achievements. As a result, [the client] is a researcher of the highest rank, and his skills and extensive research background are of tremendous advantage to the United States.”

This is a testimonial collected from an expert in the field of petroleum engineering for a client from Egypt, employed as a research scientist in the same area for his O1-A (Individual with Extraordinary Ability/Achievement) petition to USCIS. Since the criteria for the O-1 category is very clear, our team moved quickly to gather information to help the client qualify it. This meant making a thorough record of all of his academic and professional accomplishments along with supportive letters of recommendation. Soon we had found the following information:

The client has made substantial contributions to the field of petroleum engineering, specifically, in developing oil field chemicals to enhance the production and security of conventional and unconventional reservoirs. His research thus addresses some of our nation’s most pressing issues in bolstering the oil and gas industry and the national economy.

His work has resulted in 2 peer-reviewed journal articles and 6 articles in conference proceedings.
His work has been cited 30 times in other peer-reviewed journal articles according to Google Scholar.
He has conducted at least 24 reviews for international journals of repute.
His work has been funded by a U.S.-based company dealing in petroleum engineering.
He has collected 5 letters of support from experts in his field to substantiate other information in his CV.

Thus, we are very pleased to know of his case approval and we thank him immensely for his continued trust in our firm. His long-standing relationship with us has resulted in two O-3 approvals for his spouse and child as well as an NIW approval for him. We wish him great success in all future endeavors.
