Case Summary:

With 39 peer-reviewed scientific articles, 2 book chapters, and 2 conference abstracts to his name, our client is undoubtedly a force to be reckoned with. His doctoral degree and role as a senior ultrasound engineer have armed him with the knowledge and opportunities to conduct impactful research in the field of biomedical engineering. He hired North America Immigration Law Group ( to help him file an EB-1A (Alien of Extraordinary Ability) petition.

In preparing our client’s EB1A petition, we gathered a wealth of information on his various achievements in the field. For instance, we noted the 341 citations gathered from his publications as well as the 30 times he had conducted peer reviews at the time of filing. Moreover, we carefully went through his research summary and concluded that his development of biomedical imaging systems benefits patient health in the United States.

To strengthen our client’s EB1A petition, we urged him to contact other experts in the field for letters of support. To our satisfaction, our client returned with five signed recommendation letters, all of which advocated for the approval of his petition. According to one of our client’s recommenders: “[Client’s] continued work is of great importance to the U.S., as it has and will continue to further our understanding in areas such as biomedical imaging, biomedical optics, and medical engineering, which directly benefits medical care that is dependent upon innovations in imaging technology.”

Although our client had a strong case, the USCIS issued a Request for Evidence (RFE), to which we rapidly responded. We successfully dealt with all hesitations about our client’s credentials, and we are proud to list his case among our many success stories. We congratulate him for obtaining EB1A petition approval and wish him the best as he files an I-485 application (final step in the green card process) with the help of our D.I.Y. Packet.
