The applicant needs theoretical knowledge in a named scientific discipline, the required practical problem-solving or research ability, and work directly supporting professionals in that discipline. Agricultural sciences, astronomy, biology, chemistry, engineering, forestry, geology, geophysics, meteorology and physics are the listed fields.
Test the actual work against each element
Select examples that show what the applicant knows, what problems they can solve and whose professional activity the proposed work supports. A reporting line may help explain the relationship, but it cannot substitute for evidence of scientific knowledge and practical ability. Conversely, the absence of one particular supervision arrangement should not be treated as a standalone regulatory test.
Have the complete role assessed against the listed elements. Three conditions apply to every case in this category and are worth confirming alongside the technical assessment, because a role can satisfy the discipline question and still fall down on one of them. The position must be prearranged with a U.S.
employer rather than sought after arrival. The purpose must be temporary, which describes the engagement rather than anyone's ultimate hopes. And the arrangement cannot be self-employment, so a technician contracting through a company they own, with no genuine separate employer, sits outside the category regardless of how the scientific work is described.
Set these out at the start of the review as a short preliminary section, so that the discipline analysis, which takes the most effort, is not undertaken on a foundation that would not hold anyway. Where any of the three is uncertain, resolve it before the employer is asked to invest time in gathering technical evidence. Hypothetical example: an electronics technologist supporting a research engineering group has an offer describing an eighteen-month engagement, and the review begins by confirming which entity is the employer and how the person will be paid, rather than by discussing the instrumentation.
