Separate the U.S. government fees from the credential costs. The TN admission fee is listed on the USCIS fee schedule, while state licensing, examination, credential verification and the health-care certification are charged by other bodies and usually cost more in total.
Most of the money goes to licensing bodies, not immigration
The immigration fee itself is modest: the port-of-entry TN fee and the I-94 fee appear on the USCIS fee schedule, Form G-1055, and a petition filed on Form I-129 carries its own listed fee. The larger outlays belong to the credential chain. State boards charge for licensure by endorsement or examination, testing bodies charge for registering and sitting the examination, credential-evaluation services charge for verifying the Quebec program, and the health-care worker certification has its own application fee and a renewal cost if the initial certificate expires before the move. Translations of French-language transcripts and licence records must be complete and certified for U.S. use. Employers sometimes reimburse some of these charges; ask in writing which ones and whether reimbursement is conditional on a period of service, because a repayment clause becomes a personal debt if the placement ends early. Professional advice is a further, separate line.
Hypothetical example: An animal scientist accepts a research position and assumes the employer's immigration fee reimbursement covers the move. A first review separates government charges, credential records, translations, travel, state permissions and advice into who pays, when payment is due and whether it is refundable. The signed reimbursement policy, not a recruiter’s verbal assurance, settles whether an early departure creates repayment. She should also ask whether an employer-filed petition, rather than a direct admission request, changes the budget and the lead time. That choice should be made before purchasing examinations or travel.
