Case Summary:

A staff software engineer from China hired North America Immigration Law Group ( to help him attain permanent residency. In a bid to improve his chances to accomplish his goal, he wanted us to file two I-140 petitions: one under the EB-1A (Alien of Extraordinary Ability) visa category, and the other under EB-2 NIW (National Interest Waiver). Filing two petitions is not unusual as it increases one’s chances of getting an I-140 approval. We filed our client’s EB-2 NIW case first and several months later, he decided to file an EB-1A case too. In this case, our client received approval notices for both petitions.


EB-1A and EB-2 NIW Petition Packets:

As EB-1A and EB-2 NIW are two different visa categories, the requirements to qualify for either differ significantly. Despite the differences, some of the information contained in both petition packets overlapped with one another. Here are where the similarities lay:

  1. Professional Triumphs: At the time of filing, our client had published six scientific articles and his work had amassed 86 citations. We included his citation and publication record to highlight the value of his work to other researchers in the field of mathematics.
  2. Research Endeavors: Both petition packets documented our client’s research ventures on nonlinear analysis, partial differential equations, and integral equations. We demonstrated that his work improves the nation’s understanding of innovative mathematical modeling, algorithm design, and their applications.
  3. Recommendation Letters: In preparing our client’s EB-2 NIW petition packet, we helped him narrow down a list of potential recommenders who could support his bid for permanent residency. We ensured that these recommenders were experts in their field and that they had either worked with our client or were familiar with his work. Our client convinced five experts to lend their support, all of whom furnished us with strong testimonials. One of them wrote, “I have worked with many researchers over the course of my career, but none have stood out in the way that [Client] does. He is unquestionably a very talented mathematician, far superior to many others working in the field.” As it turns out, all five recommendation letters were signed within the year and we were able to use the same letters to support our EB-1A case.

We would like to congratulate our client for getting two approval notices. We are especially pleased that the USCIS approved his EB-1A petition as he does not have to wait for his priority date to become current before embarking on the final leg of the green card journey: the I-485 application. In fact, our legal team is currently helping him put together the paperwork for his I-485, and we look forward to helping him attain green card success.
