Identify the professional work
Describe the actual deliverables and responsibilities and compare them with the precise listed USMCA profession. Each profession has its own qualification rule; experience cannot universally replace a required credential. Canadian or Mexican citizenship is required, rather than Canadian residence alone. Ask for a weekly-duty outline, reporting line, and the work product expected from the professional. The useful comparison is between the real work and the listed profession, not between an appealing job title and a broad résumé.
Read the equity and control terms
Disclose shares, options, voting rights and relevant agreements. Sole or controlling ownership of the US entity receiving the professional services is outside permitted TN activity. Do not assume the percentage on a compensation summary describes every right or that a salary proves an unrelated employment relationship. Read side letters, repurchase rights, board rights, and family holdings with the same care as the option notice. Control can arise through rights that never appear in the headline ownership percentage.
Reconcile the offer and agreements
Identify the legal employer, remuneration and intended period, including any customer or intermediary arrangement. Explain what equity is currently held and what is merely proposed. A future grant should not be represented as present ownership, and existing control should not be omitted. Put the offer, payroll arrangement, service contract, and corporate chart beside one another. Inconsistency about who directs the work is a problem to resolve before it becomes a statement in an application.
Choose the actual procedure
Canadian citizens may apply for TN at a port of entry without a TN visa stamp, or a U.S. employer may file Form I-129; Mexican citizens generally need the visa process. Disclose the actual immigration history and temporary-stay circumstances before relying on any route. Choose the procedure only after the substantive record is complete. A Canadian citizen may request TN admission from an inspecting officer or through preclearance, while an employer may use USCIS Form I-129 where that procedure fits; TN cannot be used for self-directed business activity in America.
