Clarify the reimbursement agreement directly with the employer. Identify which expenses it covers and when payment occurs, instead of assuming every document or travel charge will be repaid.
Get the scope before incurring the expense
Ask whether approval is needed before ordering a service, what receipts are required and what happens if the assignment does not proceed. This is a commercial budgeting question alongside the immigration review. Confirm which evidence services are actually needed rather than spending simply because a reimbursement allowance exists.
Hypothetical example: A geoscience-data curator is offered a short U.S. project digitizing exploration archives, and the employer promises to reimburse reasonable immigration expenses. The first review should create a cost ledger with the preparer, credential provider, translation vendor, government charge, travel item, and reimbursement condition. Receipts and the employment agreement settle who has agreed to pay. Sequence the work by first confirming the classification theory, then ordering only records that support it, then checking whether the employer's policy covers the selected expenses. Money is often wasted when a worker buys an evaluation before determining whether that credential is needed, or assumes a reimbursement clause covers a refused application. Keep commercial reimbursement distinct from eligibility. The application still needs a real temporary professional role with an eligible Canadian or Mexican applicant and an employer that controls the work; funding a package does not cure self-directed employment. Save written reimbursement approvals with the supporting receipts. Keep this TN costs record aligned with final filing facts and issued source materials, then preserve a dated copy internally before formal submission for future reference and review by responsible staff if questions arise later.
