The category in brief
Your TN visa packet should document the professional work offered by the U.S. employer, the credential route in this list entry, and the requested temporary stay. Bring facts that agree across the signed letter and your supporting documents.
Keep the description on professional animal science research and program work — not daily animal care, feeding or barn chores.

What the TN list requires
Baccalaureate or Licenciatura Degree.
TN profession list, Appendix 2 to Annex 16-A of USMCA Chapter 16 (8 CFR 214.6(c))
The list title is Animal Scientist. The entry names no licence, diploma or experience alternative — the degree is the only route. Copy the credential exactly from the documents you actually hold; do not add an alternative the entry does not name.
What to explain at the counter
- Describe professional animal science work using the employer’s real responsibilities.
- State the temporary period requested, up to three years, with actual start and end dates.
- Keep the letter, résumé, offer details and interview answers consistent.
- Keep the description on professional animal science research and program work — not daily animal care, feeding or barn chores.
TNPath doesn't assess whether your evidence is sufficient; that's the officer's call
If the role or credential route is unclear, consider speaking with a U.S. immigration lawyer.
Describe the actual duties
These occupational examples are prompts, not facts about your job. Use only responsibilities your employer confirms; write them in the employer’s own terms.
- Design research studies on animal nutrition, growth, reproduction and health and analyze the results
- Develop feeding and nutrition programs for livestock production systems based on trial data
- Evaluate the effects of diets, housing and management practices on animal performance and welfare
- Analyze production, health and performance data from herds and flocks and report the findings
- Plan animal research protocols and prepare applications for animal care and ethics review
- Research physiological processes in farm animals and apply the findings to production programs
- Advise producers and organizations on animal production practices grounded in research evidence
- Prepare scientific reports and publications on animal science research
- Assess new feed ingredients, additives and technologies for use in livestock production
- Develop methods for measuring and improving animal welfare in production settings
Never add, inflate or reword duties to fit a category. Every line in the letter should be something your employer will confirm and you can describe in your own words at the counter.
Job titles that draw questions
Titles such as animal care attendant, herdsman or research technician can describe different occupations or support work. Keep the real title and describe the responsibilities honestly. TNPath’s wording flags are prompts for review, not USCIS category rulings.
Your employer must verify, approve and sign the final letter
Documents to bring
- Canadian passport
- Signed employer letter on company letterhead, original and copy
- Résumé matching the letter

Common questions
What credential does the Animal Scientist entry require?
A Baccalaureate or Licenciatura Degree. The entry names no licence, diploma or experience alternative — the degree is the only route.
What duties read as professional animal science work?
Research and program work: designing studies, analyzing production and health data, and developing nutrition and management recommendations. Daily feeding, milking, barn cleaning and routine sample processing are care or support work, and TNPath's wording flags note them for review.
Does the entry name a licence or experience route?
No. The entry names a Baccalaureate or Licenciatura Degree only. Copy the credential exactly from the documents you actually hold; do not add an alternative the entry does not name.
As a Canadian, do I need a TN visa before I go to the border?
Generally, no. Canadian citizens are visa-exempt and apply for TN status directly at a U.S. port of entry or airport preclearance, with their documents in hand. The officer decides at the counter. People still search for "TN visa", but for Canadians it's a status granted at entry, not a visa stamp. One exception: if you live outside Canada and will enter with a spouse or children who are not Canadian citizens, the State Department says you need a TN visa so they can apply for TD visas.
Will TNPath tell me whether I qualify?
No. TNPath is a document-assembly tool. It organizes the facts you provide into templates and gives general information. It doesn't make eligibility determinations or recommend case-specific strategy. Only U.S. Customs and Border Protection decides whether to admit you.
