Case Summary:

A postdoctoral associate from China hired North America Immigration Law Group ( to compile and file a convincing EB-1A (Alien of Extraordinary Ability) petition on her behalf. Our client’s extensive involvement in the field of analytical chemistry has resulted in an impressive professional portfolio. Here are some of the details that we included in her EB-1A petition presentation:

  1. Academic Accolades: With an M.S. and a Ph.D. in Chemistry, we demonstrated that our client is extremely proficient in conducting outstanding research in the field of analytical chemistry.
  2. Research Information: Thanks to the research summary that our client provided us, we were able to determine that her development of bioanalysis and bioinformatics tools for processing two-dimensional gas chromatography mass spectrometry (GCxGC-MS) data of metabolomics is very important to the United States.
  3. Professional Achievements: Up to the date we filed our client’s petition, her professional record included 235 citations to her work, 8 published scientific articles, and 35 instances of peer review experience.
  4. Signed Testimonials: To further strengthen our client’s case, we incorporated recommendation letters furnished by other expert chemists. These letters attested to the value of her work to the analytical chemistry research community as well as to the United States. According to one of these experts: “The United States, if it desires to remain a leader in analytical chemical research, should support [Client’s] continued research within its borders. It is evident that her presence in both the field and the United States is drastically important to continued research and development efforts in analytical chemistry, and especially to those related to metabolomic disease biomarker discovery.”

Because our client elected to file her EB-1A petition under Premium Processing (PP), she received notification of case approval merely 3 days after it was filed. She is now more than halfway through the complicated green card process and only has the I-485 application standing in her way. Once the USCIS approves her application, she will become an American permanent resident. We wish her the best with this and thank her to choosing our law firm.
