An EB-1A expert should be a recommender with a clearly higher or well-established profile in the field.Ideal experts include individuals such as a Fellow of a National Academy, a tenured professor at a leading university, or a C-level executive at a large, well-recognized company (for example, a Fortune 100 firm). The key is that the recommender has independent authority and credibility to assess top-tier talent in the field.It is important to include the recommender’s CV or a detailed professional bio with the petition. This allows the USCIS officer to understand the expert’s stature and why their opinion should be given significant weight.
