IN THIS GUIDE · Reviewing a first U.S. offer before accepting
Start with the TN eligibility and application overview
Separate the offer from eligibility
A signed offer is evidence of a proposed job, not a TN determination. Start with citizenship of Canada or Mexico, an eligible listed profession, the corresponding credentials, prearranged professional employment and a temporary purpose. Ask the hiring manager what work the position actually involves before selecting a category. If the recruiter says any Canadian professional qualifies, resolve that misunderstanding before using TN as the basis for an acceptance decision.
Make employer cooperation concrete
Ask who can verify the responsibilities, compensation, intended duration and organizational context. A recruiter may manage the offer while a technical supervisor understands the work. Arrange for those people to reconcile their information before a support letter is signed. As a practical planning step, identify an employer contact and a date for receiving the necessary information. An enthusiastic verbal promise to help is less useful than knowing who owns each outstanding item.
Review the commitments attached to acceptance
Read the proposed start date alongside resignation notice, relocation benefits, repayment provisions and any probationary arrangements. These are employment and financial questions that may need separate advice. Ask how the employer handles an immigration delay before committing to nonrefundable expenses. A hypothetical applicant offered relocation reimbursement only after starting should understand who bears the initial expense if authorization is delayed. A contingency discussion cannot guarantee that the immigration application will succeed.
Agree on the next decision point
Prepare a short list of resolved facts, unresolved eligibility issues and documents still needed. Decide with the employer when the offer can be reassessed if a credential or duty question remains open. Keep the intended temporary assignment accurate even if the organization hopes for a long relationship. Do not begin U.S. work merely because an acceptance has been sent; confirm that the required authorization is effective before starting the proposed employment.
Decide where the request will actually be made
Two different procedures can produce TN classification, and the choice changes what the employer must prepare and when. A Canadian citizen may generally present the supporting documentation to a U.S. Customs and Border Protection officer at a Class A port of entry or a pre-clearance location, seeking admission on the day of travel. Alternatively, the prospective employer may file Form I-129 with USCIS and wait for a decision before the employee travels. Mexican citizens generally follow a different sequence involving application for a TN visa at a U.S. consulate. Ask which route the company intends before agreeing to a start date, because a same-day request and a petition filed in advance carry different preparation, different reversibility and different consequences if an officer is not satisfied. Hypothetical example: a land surveyor whose employer assumes a border request will take an afternoon should still confirm who assembles the letter and what happens if admission is refused.
Test the temporary purpose against your own plans
An acceptance decision often reveals a mismatch between what the applicant privately expects and what the category permits. TN is a nonimmigrant classification for temporary entry; admission is generally granted for a period of up to three years, and extensions may be sought while the qualifying employment and temporary purpose continue. A stated intention to remain indefinitely, or an employer describing the position as a route to permanent residence, is a fact worth surfacing early rather than at a border inspection. Self-employment is not permitted under TN, so a candidate planning to invoice the company through a personal corporation should raise that structure before signing. Ask whether the role is genuinely prearranged with an identified U.S. employer, since TN presumes an offer that already exists. Recording an honest answer now is more useful than discovering during questioning that the applicant’s plans and the application’s premises differ.
