Case Summary:

Holder of a Ph.D. in organic chemistry, our client is focusing on synthesizing complex biologically active natural products. His research addresses some of our nation’s most pressing issues, including the development of effective therapeutic drugs for the treatment of diseases like Alzheimer’s and Parkinson’s. With this breakthrough research background, our client hired North America Immigration Law Group to assist him in filing his I-129 O1A petition and ensuring his success.

Our client is well-suited to file the O1A (Individual with Extraordinary Ability or Achievement) petition because the O1A visa category is ideal for those who can demonstrate a sustained status of national or international credit, as well as recognition for accomplishments received in their field of endeavor. To help him devise a solid O1A case on his behalf and to receive the approval notification, we agreed to take his case and started preparing it.

  • Initially, we found that he was fortunate enough to have acquired employment with one of the leading global healthcare enterprises and was offered the opportunity to be involved in synthesizing complex target compounds, designing and developing new synthetic routes, analyzing and interpreting data obtained from spectroscopic techniques, and optimizing chemical routes to targeted molecules and intermediates, bagging him a role of senior chemist I.
  • We also laid out a documented record of his authorship in the field, the 17 peer-reviewed scientific articles he published in high-impact, internationally distributed journals.
  • His publications have also been extensively recognized through 403 citations.
  • In addition, he has conducted at least 30 peer reviews.
  • Moreover, to validate his elite level of accomplishment, his work has been widely recognized by independent academics, and all of his recommenders are internationally famous specialists in the area affiliated with major universities.
  • Our client’s research has also been recognized and supported by the National Natural Science Foundation of China, the Ministry of Science and Technology, and the National Science Foundation and National Institutes of Health. The funding provided by these agencies is clear evidence of the merit of his work, as their main objective is to promote innovation across scientific disciplines for the benefit of society and to support projects that advance the health, prosperity, and welfare of the American population.

To corroborate the aforementioned, we asked our client to acquire recommendation letters in support of his research. Therefore, he provided us with the best four recommendation letters obtained from other well-established scholars in the field and one of them stated the below:

“[Client] is among the most advanced organic chemists working in the field today, and his research on natural products and the identification of drug molecules for neurodegenerative disease treatment is in high demand throughout the academic community, pharmaceutical industry, and healthcare sectors across the globe.”

As a result, his research has practical value for national public health initiatives and his O-1A visa status was approved in just 1 month and 20 days. Counting this as another victory to our more than 32K approved cases, proving that our law firm is always with our esteemed clients in every step of achieving their green cards without any hurdles.
