Read the general professional work overview
A professional transition can involve uncertainty about when existing work ends. Explain actual commitments and the new assignment without using the desired start date as an eligibility argument. The first review should produce a dated document list rather than a narrative built around a hoped-for departure. Compare the signed offer, duties, salary terms, credentials and current commitments. The decision is whether the evidence supports one temporary professional arrangement without hiding a conflict between an old engagement and the new work.
Identify the current state of each engagement
Label accepted, proposed and completed work accurately. Hypothetical example: a project may run past its expected end. Explain that uncertainty rather than presenting both employers with incompatible final schedules. Use contract end notices, project correspondence and the offer letter to mark what is completed, continuing or conditional. Preserve contradictions for resolution. The reader must decide whether a start date needs to move or whether the new employer can describe a later, accurate commencement.
Assess the new professional work independently
TN requires Canadian or Mexican citizenship, a listed profession and its prescribed qualifications. The actual new duties need assessment; a prior job title does not establish them. Degrees from institutions outside Canada, Mexico or the United States require reliable evaluation, distinct from translation. The employer letter should state the employer, purpose, detailed duties, anticipated duration, pay and credential basis. Compare it with the degree, transcript, licence and experience record where relevant. Hypothetical example: a dietitian receives a letter calling the work wellness consulting, while the attached schedule assigns nutrition assessments under a clinic director. The applicant must decide which description truthfully captures the proposed professional role.
Separate availability and authorization
Finishing the old contract does not grant permission for the new U.S. work. Identify the actual employer and temporary arrangement, including the prohibition on services to a U.S. entity solely owned or controlled by the applicant. Review the real activity and applicable process before treating preliminary work or an agreed date as authorized. Canadian citizens may request TN classification directly from CBP at entry or preclearance, while an employer may use a USCIS Form I-129 petition; Mexican citizens generally need a TN visa. TN excludes self-employment. Select the procedural route only after the employer and qualifying temporary arrangement are documented.
