No. Review what actually changed and the applicable process for the current facts.
Separate dates from substantive changes
A delay may leave some facts unchanged while a new assignment changes others. Do not assume either no consequence or automatic ineligibility without assessment.
Hypothetical example: a hydrologic-modeling analyst is asked to replace a planned data-modeling role with field sales coordination. The degree may remain the same, but the revised day-to-day duties, supervisor, and professional category must be compared before the offer is used.
For TN, confirm citizenship of Canada or Mexico, a listed professional occupation, the required qualifications, and a genuine temporary employment arrangement. A Canadian citizen may seek admission at a designated inspection location or preclearance, while a U.S. employer may submit a Form I-129 petition to USCIS. Neither path permits substantive self-employment through a U.S. entity the applicant controls.
A first review should produce an element-by-element table: the legal condition, the current fact, the primary record that proves it, and any unresolved issue. Start with the governing category rather than a persuasive title. If the role, money, entity, or family situation changed, identify whether the change affects an element or only the evidence. A missing fact should be marked as unknown and investigated; it should not be supplied through optimistic wording.
Record the conclusion in a short decision note: which required element is proved, which record proves it, and what event would change the answer. That note should be reviewed before travel, filing, or a revised employment commitment is made. For TN, the conclusion must still match the specific professional position and the actual employer arrangement; it cannot rest on a revised date or a convenient label.
