Bring the current I-94, relevant approvals, work authorization records, marriage evidence and details of the principal’s proposed TN employment. Add the spouse’s current job or school information so the review addresses activities that might be interrupted.
Use complete notices, not isolated expiry dates
An expiry date without the document’s conditions can be misleading. Keep all pages and explain any changes since issuance. If records disagree, identify the discrepancy for counsel rather than deciding privately which date or status label to follow.
The employer's letter, any petition filed on the applicant's behalf and the passport presented at inspection should all use the current legal name, with former-name documents attached alongside their linking proof. For a USCIS submission, foreign-language documents require the applicable complete English translation with the translator’s certification of accuracy, completeness and competence. Alongside the letter, carry the passport or citizenship evidence, the degree and transcript, any credential evaluation, and a resume that corroborates rather than contradicts the letter. Create a document index that names the current offer, support letter, credential, citizenship record, and any client agreement. The finished package must still establish citizenship of Canada or Mexico, a listed USMCA profession, that profession’s credential rule, and prearranged employment rather than U.S. self-employment.
