Obtain an accurate account of the real proposed duties and terms. The evidence should reflect what is actually offered rather than a preferred visa label.
Preserve the stage of the conversation
Identify conditions still unresolved. A contact’s informal encouragement should not be represented as an authorized employment commitment.
Carry proof of citizenship, the current employer support letter describing qualifying professional duties, credential documents, the most recent I-94 and admission record, and the receipt notice for whatever is pending. Keep the enrolment confirmation, the program outline showing whether any work component exists, and current employer records: pay statements, an updated duties letter if anything changed, and the original support letter for comparison. Build the record around the whole engagement: the employer letter or contract, start and end dates, weekly schedule, work location, compensation, professional deliverables, and duties during both peak and quiet periods. Build the TN file from authentic records: a signed offer or contract, an employer letter describing the actual professional services, proof of Canadian or Mexican citizenship, and evidence meeting the selected USMCA profession’s qualifications. Ask the employer to write, for each required element, a single sentence naming the record that addresses it, and to put those sentences at the front rather than leaving a reviewer to infer the mapping from a folder of attachments.
