Start with the TN eligibility and application overview
Separate the recruitment record from the offer
Arrange the interview invitation, recruiter messages and employer offer in date order. Mark which communication actually defines a position and which merely invites another discussion. Request clarification from the responsible employer where duties, pay or conditions are missing; do not fill those blanks from an advertisement or the applicant’s recollection of an encouraging interview.
Test the opportunity that the employer actually confirms
The temporary work must fit a listed USMCA profession, and the Canadian or Mexican citizen must hold its prescribed qualifications. A degree, licence or alternative must be assessed under that profession’s rule; experience is not a universal replacement for education. Where the awarding institution is outside Canada, Mexico or the United States, obtain the required reliable foreign-credential evaluation. Keep professional permission to practise distinct from that evaluation.
Record conditions without converting them into promises
Keep the proposed remuneration, duration and employer relationship accurate, including any unresolved condition. Identify ownership as well: TN does not permit services to an applicant’s solely owned or controlled US entity. A relocation package, signing promise or recruitment fee cannot establish professional eligibility or remove that restriction.
Choose a process based on the applicant’s citizenship and circumstances
Canadians generally can seek TN admission without a TN visa, while Mexicans generally follow the visa process; an employer petition may be relevant. The interview itself authorizes no US work. Give the employer a list of remaining confirmations and keep the proposed start date conditional on the actual required permission, rather than treating recruitment success as an immigration decision.
Ownership, self-employment and the state licence are separate checks
Canadian citizens may apply for TN classification directly at a US port of entry or preclearance location with the employer's letter, proof of citizenship, credentials and the applicable fee, or the employer may file Form I-129 with USCIS in advance. Write down the exact name shown on each document the case will rely on: passport, birth certificate, degree, transcripts, any professional licence, prior employment references and the employer's support letter. The listed alternatives are a baccalaureate or licenciatura degree, or equivalent professional experience supported by a statement or professional credential attesting to five years in management consulting or five years in a specialty related to the consulting agreement. TN is available to eligible Canadian and Mexican citizens for prearranged professional work in an occupation named on the USMCA professional list, provided the person meets that occupation's specific qualification rule. A process engineer relying on the degree route needs a transcript and credential evidence that clearly maps to an engineering discipline, not an adjacent technical field. For engineers, the listing provides a baccalaureate or licenciatura degree or state or provincial licence; U.S. practice authority remains a separate question. If the credential is not in English, pair the translation with the underlying record and explain any difference between the diploma's field and the offered profession. TN is temporary professional employment and cannot be used for U.S. self-employment; any ownership stake should be disclosed, and sole or controlling ownership requires particular scrutiny.
