A smoothly prepared TN visa application starts with one essential document: a credential evaluation that proves your foreign degree meets U.S. standards. Without it, even qualified professionals face delays at the border or a visa denial. Getting this right saves time, stress, and the cost of a disrupted move.
Start your TN visa credential evaluation today , a NACES-member report accepted at U.S. ports of entry and by USCIS officers nationwide.
A TN visa credential evaluation translates your foreign academic credentials into their U.S. equivalent for Canadian and Mexican professionals seeking USMCA work status. USCIS requires this report when your degree comes from an institution outside the United States, Canada, or Mexico. It proves your education matches the bachelor’s degree standard required for your job category.
The remainder of this guide covers the TN visa framework, why evaluations matter, the application paths for Canadian versus Mexican citizens. Required documentation, common denial reasons, and how International Education Evaluations (IEE) provides the fast, NACES-member report you need.
What Is the TN Visa Under USMCA?
The TN (Trade NAFTA) visa is a nonimmigrant classification for citizens of Canada and Mexico who work in specified professional occupations in the United States. Established under Section 214(e) of the Immigration and Nationality Act. This program began under NAFTA in 1994 and continues under its successor, the United States-Mexico-Canada Agreement (USMCA), which took effect July 1, 2020.
The TN visa grants Canadian and Mexican citizens temporary work authorization in the U.S. for roles across 63+ professional categories including engineers, accountants, scientists, and graphic designers. Unlike the H-1B visa, there is no annual cap and no lottery. Most initial stays are granted for up to three years with unlimited renewals.
TN status is employer-specific. You must have a prearranged job offer from a U.S. employer before applying, and the role must appear on the USMCA professional occupations list. Self-employment, freelance work, and blue-collar positions do not qualify. Spouses and unmarried children under 21 may accompany the principal applicant on TD status, which permits study but not employment in the U.S.
Why Is a Credential Evaluation Required for TN Visa Applications?
The USCIS Policy Manual requires evidence that a foreign-educated professional holds the U.S. equivalent of the degree demanded by their TN job category. A credential evaluation serves as that bridge. It compares your course of study, credit hours, institution accreditation, and degree level to U.S. academic benchmarks.
CBP and USCIS officers use credential evaluations to verify that a foreign degree equals the U.S. bachelor’s or higher degree required for a specific TN profession. Without this report, officers cannot confirm academic equivalency, which leads to Requests for Evidence at minimum and outright denial at worst.
The evaluation must come from a recognized service. IEE has been a member of the National Association of Credential Evaluation Services (NACES) since 1981, the gold standard for acceptance by U.S. immigration authorities. A NACES-member evaluation signals to reviewing officers that the analysis follows rigorous, consistent methodology.
How Do Canadian and Mexican Citizens Apply for TN Status?
While the USMCA opens TN status to citizens of both countries, the application process differs significantly. Understanding these two paths helps you gather the right documents and approach the correct venue.
Canadian citizens apply for TN status at a U.S. port of entry or pre-clearance station, requiring no advance visa. Mexican citizens must obtain a TN visa at a U.S. consulate or embassy before traveling to the U.S. border. Both paths require the same core documents: proof of citizenship, a detailed employer letter, and evidence of qualifying education.
Canadian Citizens: Port-of-Entry Processing
Canadians enjoy visa-free entry for TN purposes. You present your documents to a CBP officer at a U.S. airport, land border crossing, or pre-flight inspection station in Canada. The officer reviews your employer letter, passport, degree credentials, and credential evaluation (if your degree is from outside North America) in real time. Approvals at the border are common when documentation is complete. Some employers choose to file Form I-129 with USCIS before travel, which allows Premium Processing for a 15-calendar-day adjudication.
Mexican Citizens: Consular Processing Required
Mexican citizens must schedule a visa interview at a U.S. embassy or consulate in Mexico before traveling to the U.S. The consular officer evaluates the employer letter, degree documentation, and credential evaluation during the interview. Once the TN visa is stamped in the passport, the applicant may present it at any U.S. port of entry for admission. Like Canadians, Mexican professionals already in the U.S. on another status may change to TN through Form I-129 without leaving the country.

| Where to apply | Port of entry or USCIS | U.S. consulate or embassy |

Required Documentation for a Successful TN Visa Application
A complete application package gives CBP or consular officers everything they need to approve your case quickly. Missing or incomplete documents are the single most common cause of TN visa denials. Assemble these six items before your appointment:
- Proof of citizenship. A valid, unexpired passport from Canada or Mexico. Permanent resident cards do not qualify.
- Employer letter. A detailed letter from your U.S. employer describing your job title, duties, salary, duration of employment, and how your qualifications meet the USMCA professional category requirements.
- Original degree and transcripts. Your diploma and official academic transcripts from the degree-granting institution.
- Credential evaluation. A NACES-member evaluation report if your degree was earned outside the United States, Canada, or Mexico. IEE provides these reports with a standard three-day turnaround starting at $95 for immigration evaluations.
- Form I-129 (if applicable). Filed by your employer with USCIS for pre-approval or for changing status from within the U.S.
- Application fee receipt. Proof of payment for any required filing or inspection fees.
Common Mistakes That Lead to TN Visa Denials
According to CBP data, roughly 40% of TN visa denials at ports of entry stem from employer letter defects , vague job descriptions. Missing duties that match the USMCA category, or inadequate salary details. A credential evaluation is rarely the cause of denial but is frequently the missing link that triggers a detailed review. Avoid these patterns:
- Employer letter that does not reference the specific USMCA professional category or uses generic job duties
- Degree from outside the U.S. without a NACES-member credential evaluation to prove equivalency
- Job title that does not appear on the USMCA professional occupations list (63+ categories)
- Insufficient evidence of temporary intent and ties to the home country
- Missing signatures or incomplete forms
Professionals who submit a complete, well-organized package with a NACES credential evaluation see approval rates above 95% at U.S. ports of entry. The most common preventable errors are employer letter defects and missing degree equivalency proof , both solvable before you arrive at the border.

Frequently Asked Questions
Is a credential evaluation mandatory for a TN visa?
If your degree was earned outside the United States, Canada, or Mexico, yes. The USCIS Policy Manual requires evidence that your foreign education meets the U.S. degree standard for your TN profession category. A NACES-member credential evaluation fulfills this requirement and gives CBP officers the clarity they need to approve your application at the border.
How long does a TN visa credential evaluation take?
IEE completes standard credential evaluations in three business days , the fastest standard turnaround among NACES-member agencies. You should allow additional time for your institution to send transcripts to the evaluation service. Rush processing is available if you need the report within 24 hours.
Can Canadians apply for TN status at any U.S. port of entry?
Yes. Canadian citizens may apply for TN status at any U.S. airport, land border crossing, or pre-flight inspection station in Canada. You do not need a visa stamp in your passport. Bring your passport, employer letter, degree credentials, and any required credential evaluation. CBP officers typically complete the review during your initial encounter.
What is the difference between a TN visa and an H-1B visa?
The TN visa is available only to Canadian and Mexican citizens and covers 63+ specific professional occupations under USMCA.

The TN visa has no annual cap, no lottery, and generally allows faster processing at the border.
How much does a credential evaluation for a TN visa cost?
IEE’s immigration Document Report starts at $95. A Document + GPA Report is $130, and a full Course Report is $195. All three report types are accepted for TN visa applications. Pricing is flat-rate with no additional fees for document review or certification.
