Case Summary:

North America Immigration Law Group ( was hired to help a postdoctoral research associate from Kenya get his I-140 petition approved. Here are the several stages that we went through before emerging victorious on the other side with an approval notice from the USCIS.

  1. Evaluation: Before initiating the attorney-client relationship, we carefully evaluated our client’s credentials to establish if he qualified for a green card. Once we determined that he possessed the necessary credentials, we conducted further evaluations to determine which visa category to file his I-140 petition under. In this case, we decided to file our client’s petition under EB-2 NIW (National Interest Waiver).
  1. Gathering Recommendation Letters: Once our client had signed and returned the contract to us, we helped him narrow down a list of potential recommenders who could provide us with strong testimonials. We made sure that the elected recommenders were influential experts in our client’s field of physical chemistry. The six recommenders whom we selected all agreed to lend their support, and the recommendation letters that they signed off on were incorporated into our well-balanced EB-2 NIW petition packet. These letters furnished the USCIS with proof that our client’s work on gas phase chemical dynamics and spectroscopy is of great importance to the United States.
  1. Compiling Evidence: As with any legal case, we had to ensure that we had sufficient proof to argue our stand that our client deserved to get one step closer to permanent residency. We used Google Scholar to determine the total number of citations to our client’s work (37 citations) and established that he had published a dozen scientific papers. We used these figures, along with additional evidence that we had gathered, to convince the USCIS that our client’s investigations contribute to the American combustion industry, specifically in terms of furthering the nation’s understanding of various environments, such as those found in soot-forming processes. Our NIW petition also included a copy of our client’s Ph.D. in Chemistry and its corresponding transcripts—to prove that he is equipped with the theoretical knowledge and skills to conduct outstanding research.
  1. Refining and Submitting the Petition: After several months of carefully compiling everything we needed to present a strong case to the USCIS, we prepared a well-worded petition letter to summarize all of our findings. We then submitted the comprehensive NIW petition packet on our client’s behalf and waited for a verdict from Texas Service Center. As is clear from the publication of this success story, they approved our petition.

We would like to congratulate our client for surpassing this significant hurdle in the green card journey, and we wish him and his family well as they embark on the final portion of the journey towards permanent residency.
