It can be reviewed, but the actual prearranged work and applicable eligibility requirements must be established. Identify unresolved conditions accurately.
Clarify what is actually being offered
Compare the current duties, employer and qualifications to the relevant profession. Do not turn a possible future assignment into confirmed work merely to satisfy a desired start date.
TN turns on citizenship, a qualifying listed profession with its own credential requirement, prearranged professional employment, and temporary entry, not on a set salary threshold. Ask the professional to write out the sequence for this specific applicant: evidence gathering, the employer's support letter, any petition, any consular step, and the admission itself. TN admission requires prearranged professional work in an occupation actually listed under the USMCA framework, held by an eligible Canadian or Mexican citizen who meets that occupation's own qualification standard. Check applicable practice requirements separately; the TN credential listing should not be represented as a blanket licence to perform every regulated act in the United States. If the licence carries a restriction, whether a category limited to a class of work or a supervision condition, decide before travel whether the offered duties fit inside it.
