Assess the structure first: which items are professional fees, which are government charges set elsewhere, and which are variable third-party costs. Then confirm current amounts from official sources and provider quotes rather than relying on a figure recalled from a previous case.
Verify amounts at their source
Government charges change and differ by step and by route, so the reliable check is the official schedule at the time of filing, not a bundled estimate. Third-party costs such as translation, courier, or credential evaluation should carry their own quotes. Ask what happens if a charge rises between the quote and the filing, and whether the employer's commitment is capped at a stated amount or covers the actual cost.
The state board sets its own licensing charges and the credentialing organisation sets the certification fee; neither is a U.S. immigration fee and neither appears in the USCIS schedule. At the border the applicant pays the TN application fee and the I-94 issuance fee, both modest amounts set out on the USCIS fee schedule, and nothing else beyond travel. Ask any professional adviser whether the fee covers preparing the experience table and responding to follow-up questions, or only reviewing what the applicant assembles.
