For a case relying on an overseas degree, budget for any required evaluation and translations. If relying on an existing qualifying licence, confirm which credential services are actually needed. Destination-state licensing charges, when applicable, and professional immigration-review fees are separate items.
Scope the credential work before the legal work
Ask early whether the evaluation and translation costs are one-time or whether a follow-up request from the evaluator is likely given the specific degree. Confirm current government fee amounts directly with the relevant agency at the time of filing rather than relying on a fixed figure quoted in advance. Spending on licensing steps before the TN duty match is confirmed risks paying for a track that turns out to be unnecessary.
Two further items belong in that sequencing. Ask what a second evaluation would cost if the first turns out to address the wrong comparison, since that is the most common way money is wasted here and the answer influences how carefully the initial instruction is drafted. And price the employer's own effort, which is rarely invoiced and frequently decisive: a partner's time describing the role honestly, an internal review of the wording, and the wait for an authorised signature.
Hypothetical example: an architect working on grocery formats has a straightforward credential position, and the schedule is governed entirely by a practice that takes five weeks to produce a two-paragraph letter because the only person who may sign it is on a project abroad.
