TN Government Filing Fees — Complete 2026 Cost Guide

What TN Government Filing Fees Actually Cost

TN status under NAFTA (now USMCA) operates differently from other employment-based nonimmigrant categories. At a port of entry or pre-clearance location, Canadian citizens applying for TN status pay no government filing fee—the officer reviews the qualifying letter and supporting documents at the inspection itself. For Mexican citizens and for any applicant whose employer files Form I-129 with USCIS, the government filing fee is $460 as of 2026. This is the base Form I-129 petition fee for nonimmigrant workers, distinct from the H-1B cap-subject fee structure that includes additional amounts.

The zero-cost border route surprises applicants who compare it to H-1B, where fees exceed $1,000 before any petition reaches an officer. Here's the honest answer: TN is the only major work-visa category where the statute allows instant adjudication at the border without an advance petition, and CBP does not charge a filing fee for that service. The trade-off is immediate scrutiny—no advance notice, no RFE process, just approval or denial on the spot.

Understanding which route applies to your situation determines the total government cost. Canadian citizens may choose between the two routes depending on timing and complexity. Mexican citizens must use Form I-129 because the statute requires advance USCIS approval before they can present themselves at a consulate or port. Employers filing on behalf of any TN applicant use Form I-129 regardless of nationality. The fee structure, filing location, and procedural options all hinge on that choice.

The Two Filing Routes and Their Fee Structures

The TN category permits two distinct application methods. The government fee—or absence of one—follows the method, not the applicant's profession or employer.

Port-of-Entry Application (Canadian Citizens Only)

Canadian citizens may apply for TN status directly at a U.S. port of entry, a pre-clearance location in Canada, or certain designated airports. The applicant presents a qualifying offer letter, credential documentation, and proof of Canadian citizenship to a CBP officer. The officer adjudicates the application during the inspection. There is no government filing fee for this route. The only costs are document preparation and any third-party fees (credential evaluations, translations, or legal review).

This route delivers immediate decisions but offers no appeal mechanism. If the officer finds the application deficient, the applicant is denied entry for TN purposes on that occasion. Reapplication is permitted, but the denial is noted in the system.

Form I-129 Petition (All Applicants, Required for Mexican Citizens)

Employers may file Form I-129, Petition for a Nonimmigrant Worker, with USCIS on behalf of any prospective TN employee. Mexican citizens must use this route because the statute prohibits them from seeking TN status at a port of entry without prior USCIS approval. Canadian citizens may also use this method when advance certainty is preferred—filing before travel eliminates the risk of a border denial.

As of 2026, the Form I-129 base filing fee is $460. This fee applies across all I-129 categories—TN, H-1B (non-cap), L-1, O-1, and others—but additional fees attach to some categories. TN petitions do not trigger the H-1B-specific fees (the $750 or $1,500 ACWIA fee, the $500 fraud-prevention fee, or Public Law 114-113 fees). Premium processing is available for TN petitions at an additional cost set by USCIS; confirm the current premium-processing fee on the USCIS fee schedule at uscis.gov/forms before selecting that option.

Approved I-129 petitions generate a Form I-797 approval notice. Mexican citizens present that notice at a U.S. consulate to obtain a TN visa stamp, then enter the United States. Canadian citizens present the I-797 at a port of entry without needing a visa stamp, because Canadian citizens are visa-exempt for TN purposes.

What the $460 I-129 Fee Covers

The Form I-129 filing fee pays for USCIS adjudication of the petition. It does not include premium processing, which is optional and carries a separate fee. It does not cover any consular visa-application fee for Mexican citizens who must obtain a TN visa stamp after I-129 approval. The DS-160 nonimmigrant visa application and the consular interview are separate State Department processes with their own fee, currently set by the State Department's visa fee schedule at travel.state.gov.

The $460 fee is the same whether the petition requests initial TN status, an extension, or a change of employer. USCIS does not discount extension filings or charge extra for amendments. The fee is per petition, not per beneficiary—if an employer files for multiple TN workers simultaneously, each requires a separate I-129 and separate $460 fee.

Premium Processing for TN Petitions

Premium processing guarantees a USCIS response within a set number of calendar days from the date USCIS receives the request. As of 2026, confirm the current premium-processing timeframe and fee on the USCIS premium-processing page before filing—both the fee amount and the guaranteed window have changed over time and are subject to adjustment.

Premium processing does not guarantee approval. It guarantees a decision—approval, denial, or RFE—within the window. If USCIS issues an RFE under premium processing, the clock pauses while the petitioner responds, then resumes when USCIS receives the response.

Premium processing is filed on Form I-907, either concurrently with the I-129 or as an upgrade to a pending I-129. The premium-processing fee is in addition to the $460 base I-129 fee. Not all USCIS service centers accept premium processing for all petition types at all times; verify current availability on the I-907 instructions before selecting this option.

Additional Costs Beyond Government Fees

Government filing fees are only one component of total TN application costs. Applicants and employers commonly incur:

• Credential evaluations: If the applicant's degree is from a non-U.S. institution and the profession requires a specific credential, a credential-evaluation service may be needed to establish U.S. equivalency. Evaluation costs vary by provider and complexity.
• Translations: Documents in languages other than English must be accompanied by certified translations. Translation fees depend on document length and language.
• Legal fees: Many applicants retain immigration counsel to draft the employer letter, review credentials, and advise on the strongest application strategy. Legal fees vary by market and case complexity. The Law Offices of Peter D. Chu in San Diego offers an initial consultation for $250 to assess TN eligibility and application options—contact the firm at 858-268-8823 or visit peterchu.com to schedule.
• Consular visa fees (Mexican citizens only): After I-129 approval, Mexican TN applicants pay the nonimmigrant visa application fee to the U.S. consulate and attend an in-person interview. The consular fee is separate from the I-129 filing fee and is set by the State Department.
• Travel costs: Port-of-entry applicants travel to the border or pre-clearance location for the inspection.

These costs are not government filing fees but are part of the total expense of obtaining TN status.

How TN Fees Compare to Other Work Visas

TN government fees are lower than most employment-based nonimmigrant categories because the statute does not impose the supplemental fees that attach to H-1B and certain L-1 petitions. The comparison:

The absence of supplemental fees makes TN one of the most cost-effective work-visa options for Canadian and Mexican professionals in qualifying occupations. The trade-off is the limited scope—TN applies only to specific professions listed in the USMCA treaty annex, and the qualifying criteria for each profession are strict.

What If My Employer Refuses to Pay the Filing Fee?

Immigration law does not mandate that employers pay the I-129 filing fee for TN petitions. Some employers cover all petition costs; others require the employee to reimburse some or all fees. The legal issue is whether requiring reimbursement violates wage-and-hour laws or employment agreements, not immigration regulations.

For Canadian citizens, the border route eliminates the I-129 fee entirely, making employer reimbursement moot. The applicant controls the timing and bears no government filing cost. If the employer prefers the certainty of an approved I-129 before the employee relocates, the parties negotiate who pays the $460.

For Mexican citizens, there is no alternative to the I-129 route. If the employer will not file the petition or will not pay the fee, the applicant cannot obtain TN status. In that situation, evaluate whether the position and offer justify covering the cost personally, or whether another visa category (such as H-1B if the employer participates in that process) might distribute costs differently.

What If I Need to Extend My TN Status?

TN status is granted in increments up to three years per approval. Extensions are permitted indefinitely as long as the applicant maintains nonimmigrant intent—the intention to return to Canada or Mexico when TN status ends. There is no maximum number of TN extensions and no cumulative time cap, unlike H-1B's six-year limit.

Extension applications follow the same fee structure as initial applications. Canadian citizens may apply for an extension at a port of entry (no fee) or via Form I-129 ($460). Mexican citizens must file Form I-129. Premium processing is available for extension petitions on the same terms as initial petitions.

Filing an extension before the current TN status expires preserves work authorization under the automatic 240-day extension rule, provided the extension petition is filed on time and requests the same employer and position. Filing late forfeits that protection.

What If I Am Denied at the Port of Entry?

Port-of-entry TN denials are final for that application attempt. CBP does not issue RFEs or allow corrections during the inspection. The officer either admits the applicant in TN status or denies entry for that purpose. A denial does not bar future TN applications, but it is recorded, and subsequent officers will see it.

If denied, the applicant may:

1. Reapply at a later date with corrected or additional documentation addressing the deficiency the officer identified.
2. File Form I-129 instead, shifting the adjudication to USCIS. USCIS officers apply the same legal standard but allow RFE responses if the initial evidence is insufficient. This route trades immediacy for procedural safeguards.
3. Consult an immigration attorney to assess whether the denial was based on a correctable documentation issue or a substantive ineligibility. Some deficiencies—such as a profession not listed in the treaty annex or credentials that do not meet the minimum requirements—cannot be overcome by refiling.

Denials at the port of entry are not appealable. The administrative review process available for visa denials at consulates does not apply to CBP TN decisions.

Direct Answer: Why TN Costs Less Than H-1B

Let's be direct: TN costs less because Congress never imposed the supplemental fees on it. The H-1B statute requires fees funding workforce training and fraud prevention. The L-1 statute added similar fees. TN operates under the USMCA treaty implementation statute, which predates those fee regimes and has not been amended to add them. The result is a base I-129 fee only—no ACWIA fee, no fraud-prevention fee, no Public Law 114-113 fee—and a zero-cost option at the border for Canadians. The lower cost is structural, not a USCIS discount.

Paying the Fee: Accepted Methods and Timing

Form I-129 petitions filed by mail require payment by check or money order payable to "U.S. Department of Homeland Security." Personal checks, cashier's checks, and money orders are accepted; cash is not. The check or money order must accompany the petition package.

Petitions filed electronically (if the petitioner has a USCIS online account) allow credit card or ACH debit payment during the filing process. Confirm current electronic-filing availability for Form I-129 TN petitions on the USCIS website, as not all petition types are available online.

Payment is due at filing. USCIS does not invoice petitioners or accept installment payments. If the check is returned for insufficient funds, USCIS rejects the petition, and the package is returned unfiled. Premium-processing fees, if selected, are paid on the same schedule and with the same methods.

Fee Refunds and Rejected Petitions

USCIS refunds filing fees only if the petition is rejected—meaning USCIS declines to accept it for processing due to a filing defect such as an unsigned form, missing fee, or incorrect fee amount. Once USCIS accepts the petition and issues a receipt notice, the fee is non-refundable even if the petition is later denied or withdrawn.

Premium-processing fees are refunded if USCIS fails to meet the guaranteed processing window, but not if the petition is denied or withdrawn within the window. The refund is automatic; petitioners do not need to request it.

Rejected petitions are returned to the sender with an explanation of the defect. Correcting the issue and refiling requires submitting a new fee.

Planning for TN Fee Costs in 2026

Budget planning for TN applications should account for:

• Government fees: $0 (border route for Canadians) or $460 (Form I-129 for Mexicans and any employer-filed petition).
• Premium processing (optional): Verify the current fee on uscis.gov/i-907 if faster adjudication is needed.
• Consular visa fee (Mexican citizens only): Verify the current fee on travel.state.gov if I-129 approval requires a consulate interview.
• Third-party costs: Credential evaluations, translations, and legal counsel.

Government fees change when USCIS publishes a new fee rule in the Federal Register. The current fee schedule lists fees by form number; cross-check uscis.gov/forms before filing to confirm no interim adjustment has occurred.
