IN THIS GUIDE · Changing to a new U.S. employer
Start with the TN eligibility and application overview
Assess the new offer independently
Confirm that the new proposed work fits a listed TN profession and that the applicant meets its credentials, citizenship, and temporary-entry requirements. Do not treat approval for the old role as advance approval for the new one. Compare actual duties, employer identity, and terms, including any responsibilities added during recruitment. A hypothetical move between similarly titled positions can still involve different work, so the new employer needs to support its own professional employment proposal.
Identify the correct change process
A change of employer needs the appropriate immigration authorization before work for the new employer begins. The available procedure depends on the applicant’s circumstances and may involve an employer petition or an application for readmission. Select the route with advice based on current status, nationality, travel plans, and the offer. Do not borrow assumptions from another work category or equate a filing receipt with permission to start the new TN job.
Plan the gap between employers
Write down the expected last day with the current employer, the current admission expiration, and the proposed first day with the new employer. Have any gap assessed before relying on it for a transition plan. This guide does not calculate a grace period or determine a person’s continued status. Ask the new employer for a conditional start date, and assess relocation, benefits, and household expenses if authorization takes longer than hoped.
Check the resulting records
After the change is authorized, review the decision and any new admission record against the new employment arrangement and authorized dates. Keep prior records so the status and employment history remain understandable. If travel occurs during a pending process, obtain case-specific advice about its effect rather than assuming the application continues unchanged. Do not work for both employers during an overlap unless the authorization needed for each employment arrangement has been addressed.
What a first transition review actually produces
A first consultation on an employer change should end with four written outputs, and it is worth asking for them explicitly. The first is a category finding: whether the new proposed duties fall within a listed profession in the USMCA professionals appendix and whether the applicant holds the credential that category requires, assessed on the new job rather than carried over from the old one. The second is a route finding, identifying which process is available for authorising work with the new employer given the applicant location, current admission and travel plans. The third is a gap analysis listing the documents and facts still missing, with a name against each. The fourth is a statement of what the review could not determine, which is the output most often omitted and most often needed later. What a first review cannot produce is an authorised start date, because TN requires prearranged employment with the employer concerned and the authorization must be effective before work for that employer begins. Self-employment is not permitted either, so an offer routed through the applicant own company changes the question entirely.
Hypothetical example: a familiar title and an unfamiliar job
Hypothetical example: a pharmacologist holding TN status with a contract research organisation receives an offer from a clinical laboratory group, with a similar title and broadly similar pay. The first review looks past both. It asks what the new duties actually are, because a title reading the same can cover work that has drifted toward operations, supply management or commercial responsibilities sitting outside the professional category. It asks who the legal employer is, since laboratory groups frequently operate through several entities and the offer letter may name a different one from the recruiting manager. It asks whether the credential on file matches what the new category requires. The output is a short finding on each of those points and a list of what must be confirmed with the new employer before anything is drafted. An earlier approval for the previous role is useful history and evidences what was accepted then; it does not carry across to a different employer or a different job.
