TN Visa Interview Questions: What CBP Officers and Consular Officers Ask

The TN interview — whether at a Canadian border crossing, Toronto Pearson's pre-clearance, or a U.S. consulate in Mexico — is not a formal sit-down examination. It is a 10–30 minute professional conversation where an officer tests three things: whether your duties match the USMCA profession, whether your qualifications support those duties, and whether you intend to return home.

Understanding what officers are actually testing makes the interview far less stressful.

What CBP Officers Are Evaluating

CBP officers at the border do not care about your job title, your LinkedIn connections, or how impressive your company is. They are adjudicating whether your application satisfies the legal standard: that your activities qualify as "business at a professional level" under USMCA Appendix 2.

Every question they ask traces back to one of three concerns:

1. Profession fit: Do your duties match the USMCA profession category you applied under?
2. Qualification fit: Does your education or experience satisfy the minimum requirement for that category?
3. Nonimmigrant intent: Are you actually planning to go back to Canada (or Mexico) at the end of this status?

Common Questions at Land Border and Airport Pre-Clearance (Canadians)

"What will you be doing in this position?"

This is the core question. The officer wants to hear you describe your duties in terms that match the USMCA profession definition — not your job title, not your team structure, not your company's product roadmap.

If you are applying as a Computer Systems Analyst: "I analyze business requirements, evaluate existing systems for inefficiencies, design technical specifications for software solutions, and assess the feasibility of proposed system changes."

If you are applying as an Engineer: "I apply engineering principles to the design and development of [specific type] systems, including [relevant technical activities]."

If your answer sounds like project management or people management, expect follow-up questions.

"What is your degree in?"

Simple question, potentially complex answer depending on your profession. A degree in "Computer Science" is not automatically accepted as qualifying for the "Engineer" category. An officer may probe whether your program had engineering accreditation or whether you have a provincial engineering license.

Answer factually: name the degree, the institution, and the conferral date. If your degree field doesn't obviously match the profession (e.g., a BS in Biology applying as a Computer Systems Analyst with a diploma/certificate + 3 years experience), be ready to explain the alternative qualification pathway.

"Have you been denied TN status before?"

Answer honestly. The officer can see prior applications and withdrawals in the CBP system. If you had a prior denial or withdrawal, say so, and briefly explain what was different or deficient and what you changed in this application.

"What is your salary?"

Straightforward. This cross-checks with the support letter. Know the number before you arrive.

"How long have you been working in this field?"

Relevant particularly for Management Consultant (which allows 5 years experience in lieu of a degree) and for demonstrating qualifications in borderline cases.

"Do you have family in the United States?"

This probes nonimmigrant intent. Having family in the U.S. is not automatically problematic — TN holders can have spouses and children in the U.S. on TD status. The question is whether your circumstances suggest you are planning to stay permanently. Answer honestly and matter-of-factly.

"Are you planning to apply for a green card?"

If you are not currently pursuing one, say so simply. If you are in the process, this is a complex area. TN and green card applications can coexist with careful management — filing an I-140 while on TN is a high-risk strategy that many immigration attorneys advise against doing concurrently with border renewals. Do not lie about a pending I-140; officers can see it.

"Where will you be working?"

They are verifying the U.S. employer is real. Know the company's address and location. Remote work arrangements deserve special care here — if you will primarily work from Canada, you may not need a TN at all; if you will be physically present in the U.S., your answer should reflect that.

The Follow-Up Pattern to Watch For

Officers do not ask questions randomly. If a question gets a vague answer, expect a follow-up that narrows the scope. The pattern typically goes:

1. Broad question: "What will you be doing?"
2. Vague answer from applicant: "I'll be working on software projects."
3. Narrow follow-up: "Can you be more specific? What does your typical day involve?"
4. More vague answer: "Coding, meetings, stuff like that."
5. Result: Denial for failure to establish the duties constitute Computer Systems Analyst work.

The way to avoid this is to prepare a 60-second description of your core duties that uses the vocabulary of the USMCA profession definition. Practice it out loud. You should be able to answer "what do you do?" without hesitation and in terms that map directly to your support letter.

Consular Interview Questions (Mexican TN Applicants)

U.S. consulates in Mexico focus on the same three areas but have additional emphasis on Section 214(b) — the presumption that every nonimmigrant applicant intends to immigrate. Mexican TN applicants must affirmatively overcome this presumption.

Additional questions at consular interviews:

"What ties do you have to Mexico?"

This is the 214(b) question. Strong ties include: property ownership, family (parents, siblings, children) in Mexico, ongoing business interests, a Mexican employer or client relationship, a permanent job offer to return to. Be specific.

"Why are you going to the United States?"

Explain the professional opportunity: the salary differential, the specific project or employer, the temporary nature of the role.

"Have you applied for any other U.S. visas?"

Answer factually. Prior visa applications — whether approved or denied — are visible to the consular officer.

"What is your Cedula Profesional number?"

For Mexican professionals, the Cedula is the government-issued professional license. The officer may ask about it to verify your professional qualifications. Know your number and have the document available.

"When do you plan to return to Mexico?"

This reinforces the temporary intent requirement. Even if you do not have a specific return date, you should be able to articulate that you plan to return — you have family there, property, future career intentions.

What Officers Do Not Care About

• Your company's prestige or valuation
• How urgently your employer needs you to start
• That you have been in your role for many years
• Your LinkedIn profile
• Internal job titles that don't match USMCA categories

One officer famously said during a denial that they "don't Google job titles or care about LinkedIn." That is not an exception — it is standard adjudication practice. Officers care about duties as presented in the letter, qualifications as evidenced by credentials, and intent as expressed by you in person.

Preparing for the Interview

The best preparation is a thorough knowledge of your own support letter. Read it multiple times before arriving. The duties in the letter should be the duties you describe in the interview — not a verbatim recitation, but a natural articulation of the same functions.

Know your degree, your conferral date, and how it qualifies you for the specific USMCA profession. If your degree required a credential evaluation, read the evaluation so you can speak to its conclusions.
