Case Summary: 

North America Immigration Law Group ( was hired by a research associate from China who wanted to obtain permanent residency. To get a green card, one must first go through two steps: I-140 petition and I-485 application. We helped our client with the first step and thanks to Premium Processing, received an approval notice a mere seven days after we filed the case. Besides our convincing presentation demonstrating that our client’s work is important to the United States, here are some other aspects of the case that persuaded the USCIS to approve our client’s EB-1A petition:

Strong qualifications:

With over 120 citations to his work, 19 publications, and extensive experience assessing 12 manuscripts, our client indubitably possessed the skills and credentials needed to qualify his case under the EB-1A (Alien of Extraordinary Ability) visa category.

Compelling Recommendations:

It was not sufficient to simply submit our EB-1A petition without any third party opinions. Recommendation letters are important to every green card case as they inform the USCIS that the research done is not only important to the scientist concerned, but to many others within the scientific community. Not just that, they verify the findings and lend support to the petition. In our client’s case, six recommendation letters were submitted to the USCIS, all of which were contributed by experts in his field of dentistry. One of these letters firmly stated that “[Client’s] dedication to advancing the latest dental research and his high publication and citation record all point to what can be reasonably expected from him as he further explores questions surrounding dental adhesive quality. His success thus far has greatly expanded the ability of dental researchers to quickly and efficiently develop better quality, longer lasting dental adhesives. This work has undeniable benefits for many people across the world. As he has proven to be a pioneer in the field of dentistry, it is doubtful that [Client] could be replaced with another scientist.”

Outstanding Research Endeavors:

Our petition letter also contained information on our client’s many research exploits on improved filling and adhesion dental materials that exhibit increased strength and durability. We established that our client’s strong educational and professional background have allowed his investigations to be original and applicable towards the fabrication, processing, and evaluation of novel dental filling materials and new, durable dental adhesives, which greatly benefit the dental health of all Americas.

We are pleased at the outcome of this EB-1A case, and we thank our client for engaging our legal services. North America Immigration Law Group wishes him well as he continues to progress the important field of dentistry.
