Applicants must present evidence of sustained national or international acclaim and that their achievements have been recognized in the field of expertise. In determining whether you have enjoyed “sustained” national or international acclaim, immigration officers must be convinced that such acclaim is uninterrupted and ongoing. If you were recognized for a particular achievement several years ago, you must have maintained a comparable level of acclaim in the field of expertise since you were originally afforded that recognition.
Depending on the nature of the acclaim, a one-time major achievement, such as a Nobel Prize, might satisfy this requirement, provided it is probative of the fact that you have reached the summit of your occupation. In the absence of such a major, international recognized award, however, you may not rely solely on your past achievements to establish your eligibility for classification as an alien of extraordinary ability.
