Expect licensing body fees, examination and verification charges, a possible credential evaluation, and courier costs, alongside the ordinary costs of preparing the TN case. Confirm current amounts with each body directly, and settle in writing who pays which item before accepting.
Split the budget by who charges it
Licensing costs are set by the regulator and are unrelated to immigration fees, so treat them as two separate lines. Ask the employer explicitly whether it reimburses examination attempts, verification requests, or legal review, and whether reimbursement survives a delayed start. Where credentials come from abroad, an evaluation may be an added expense on one track only. Amounts change, so verify rather than budgeting from a quoted figure.
Government charges and professional costs are distinct from the evidence required to qualify for TN. Translation and credential evaluation are separate services with separate fees, and paying for an evaluation does not produce a translated civil document. A reliable foreign-credential evaluation is worth paying for when the regulation requires one. Government charges differ between port-of-entry presentation and a Form I-129 petition and change over time; take the port-of-entry fee from the CBP schedule and the petition fees from the USCIS G-1055 schedule on the day of filing.
