Case Summary:

After thoroughly examining the documentary proof and supporting testimonies that we have included with our client’s National Interest Waiver (NIW) application, it is established that he is a member of the professions holding an advanced degree (M.E. in environmental engineering and management) and his research on the development of practical solutions to elevate and protect water resources quantity and quality by using hydrological resources, evidently has both substantial merit and national importance.

When our client hired North America Immigration Law Group to help him secure the NIW approval, without any delay, we commenced the assessment of his qualifications and gathered the most exceptional and relevant information to include in his petition, ultimately leading him to achieve victory in his NIW petition without encountering any impediments.

To emphasize our client’s educational background, professional experience, and expertise, as well as his record of publication and citation, and the history of successful research in his chosen field, we have focused on these specific aspects and incorporated the following details into our personalized petition package:

  • We noted that as an expert in the field of ecosystem science, our client intended to continue his research on developing practical solutions to elevate and protect water resources, and thereby his research is relevant to clean water access and pollution issues in the United States.
  • We also deduced that his research is of great importance because it advances the world’s critical crisis of clean water access.
  • In addition, we specified that he published 12 peer-reviewed journal articles (6 of them first-authored) in no fewer than 5 highly ranked peer-reviewed journals, which reflects his peers’ recognition of the value of this research.
  • In addition to accomplishing and publishing his research findings, he has significantly impacted his colleagues in the field. To elaborate, his published works have been cited a remarkable 37 times, illustrating his extensive recognition and reliance in the field of ecosystem science.
  • The provided citations clearly demonstrate that our client is actively pushing the boundaries of his field by conducting research on reducing environmental impact through sustainable and nature-based approaches. Moreover, his study has secured funding from esteemed organizations such as the National Fish and Wildlife Foundation and the European Union. Hence, his research serves as concrete evidence that it aids in safeguarding the quality and quantity of water resources through the development of hydrological assets.
  • Also, we have observed his enthusiastic involvement as an evaluator of the work conducted by other professionals in the same field. Specifically, he has successfully carried out a total of 10 peer reviews up until now.

The aforementioned evidence indeed validates the beneficial nature of our client’s research for the United States, leading to the exemption of job offers and labor certification requirements. As a result, he has successfully proven his eligibility for a national interest waiver, demonstrating his exceptional qualifications. Incredibly, his petition was approved in a short span of 13 days from the date of filing his case, thanks to a premium processing service upgrade. Thus, we are delighted that our client entrusted our law firm with presenting his I-140 NIW petition and extend our heartfelt wishes for his future endeavors.
