Yes, if the regime is the company's own process and the technician applies it at an advanced level. Neither a degree nor a large employer is a requirement; specificity of the knowledge is.
The regime, not the résumé, is what the standard measures
Specialized knowledge is defined as special knowledge of the company's product, service, research, equipment, techniques, management or other interests and its application in international markets, or an advanced level of knowledge of the company's processes and procedures. A washed-rind ripening regime developed by the owner, recorded in company manuals and adjusted by the technician over four years is squarely a company process. The petition needs to show that the knowledge is not commonly held in the industry, that it is not easily transferable to a newly hired U.S.
cheesemaker without significant training, and that the U.S. dairy needs it. Evidence of the technician's own role, such as revision histories and batch sign-offs, establishes that he holds the knowledge rather than merely works near it.
The absence of a degree is irrelevant. The company's size matters only to the extent it affects fees and the plausibility that the U.S. entity is doing business, which an operating dairy demonstrates.
