Review the revised duties and terms and update the relevant evidence accurately. A completed translation is not a reason to submit an obsolete offer. The applicant still needs the actual lawful permission for the work that will be performed.
Compare the changes before setting the start
Identify what changed in the employer, duties, duration or compensation. Assess whether the same profession and procedure remain appropriate. Do not begin US employment merely because the earlier version was ready for submission.
A first review should create a dated sequence from the signed offer through the chosen admission or petition step, travel, and the first lawful workday. Match each date to proof: a current employer letter, the credential record, citizenship document, and any required licensing evidence. Recheck the file if duties, worksite, employer, compensation, or ownership changes before presentation. A Canadian may seek TN admission on entry, while a qualifying employer may use Form I-129 submitted to USCIS; neither path turns a controlled U.S. business into permitted TN work. Hypothetical example: A laboratory-water-quality analyst learns one week before travel that the client, rather than the named employer, will direct all assignments. The parties should clarify the actual employment relationship and revise the plan if necessary. Travel reservations do not establish eligibility, and beginning services before the proper authorization is obtained can create avoidable risk.
Before setting the date, confirm citizenship of Canada or Mexico and the selected profession’s qualification rule alongside the procedural choice.
Pause the filing sequence and compare the executed offer with the translated version line by line. Reassess the occupation, core duties, employer, pay, worksite and requested period; then confirm that Canadian or Mexican citizenship and the listed profession’s particular qualifications remain documented. TN requires prearranged professional work and does not permit U.S. self-employment. A Canadian may seek admission at a port of entry or the employer may pursue Form I-129, but neither route justifies starting before authorization. The recurring mistake is keeping a convenient appointment or start date while submitting terms the parties no longer intend to follow.
Hypothetical example: A Saguenay registered nurse receives a revised offer after her French credentials were translated: the employer changes the position from bedside nursing to recruiting and onboarding. She postpones travel, obtains the final duty statement and checks whether the new work still fits the Registered Nurse profession and licensing requirements. If it does not, an accurate old translation cannot support the changed job. Only after selecting a valid route does the employer reset her proposed start.
