Licensing is usually the larger cost. State application and examination fees, credential verification and document ordering are separate from the immigration charges on the USCIS fee schedule.
The regulated profession carries its own bill
The immigration charge depends on whether the application is made at a port of entry or through an employer petition, and the current amounts are on the published fee schedule rather than in any summary, since they change. For a regulated profession the other costs are frequently larger and arrive earlier: the state board's application fee, examination fees where required, verification of the veterinary degree through a recognized service, certified transcripts, and licence verification from the provincial regulator. Some employers reimburse licensing costs and some do not, which is worth settling in the offer negotiation rather than after arrival. Travel and the family's own document costs sit outside both budgets.
Hypothetical example: A Canadian architect accepts an offer to design an adaptive-reuse project and learns that a state examination is still required before independent practice. The offer should say which party pays the professional-registration charges, translations, and any petition expenses. Receipts and the current government fee page settle actual amounts; an old estimate does not. Decide whether reimbursement is a condition of accepting the job, then record it in writing. That prevents a disagreement when the first licensing invoice arrives before employment begins.
Ask for that allocation before declining another offer or committing to professional registration.
