Establish the issuer without rewriting the degree
Use the institution’s records or other reliable evidence to connect the former and current names. Distinguish a simple name change from a merger or another event whose effect needs explanation. Do not issue an unofficial replacement credential. If the degree is from an institution outside Canada, Mexico or the United States, the TN regulation requires a reliable foreign-credential evaluation. Match each responsibility to the selected profession. A detailed signed employer letter, the relevant credential record, and a direct description of the assignment normally resolve more than a title alone. Review ownership early: a nominal supervisor cannot cure an arrangement in which the applicant actually owns or controls the U.S. receiving business.
Apply the engineer qualification and duties
The engineer listing provides a baccalaureate or licenciatura degree, or a state or provincial licence. A requirement to be licensed for particular U.S. practice is a separate question. Explain the actual professional duties and credential relationship rather than assuming every role containing engineer qualifies or every name discrepancy defeats the case. The first review should show who will direct the work, pay for it, and receive its benefit. That factual arrangement, rather than a phrase in a contract, determines whether the professional activity is genuinely prearranged employment. Where a licence is relevant to practice, keep that regulatory question separate from the immigration credential question.
Retain citizenship and the real employment arrangement
TN requires Canadian or Mexican citizenship, qualifying prearranged professional activity in a listed profession, that profession’s own qualification rule and temporary entry. The employer may be U.S. or foreign, but working for a U.S. receiving enterprise the applicant solely owns or controls is prohibited TN self-employment. Disclose ownership and control rather than relying on a nominal supervisor to change that result. A Canadian citizen may apply at a port of entry without a visa stamp, or a U.S. employer may file Form I-129; TD dependants may study but may not work. Sequence qualification and identity evidence first, the employment arrangement second, and the travel or petition choice third. A Canadian citizen may request TN at inspection or preclearance, while an employer may submit Form I-129 to USCIS. TN is temporary professional authorization and does not permit self-employment for a U.S. business the applicant owns or controls.
