If you’re a Canadian or Mexican citizen seeking professional work in the United States, the TN Visa is one of the most efficient options available. Created under the United States-Mexico-Canada Agreement (USMCA), this nonimmigrant visa allows eligible individuals to work in pre-approved professional roles—without the lengthy process other employment visas require.
So, how do you apply for a TN Visa in the USA? In this article, we’ll walk you through the process and how to avoid common pitfalls—with guidance from Maria Fitzmaurice PC, a trusted immigration attorney in San Antonio, Texas.
What Is the TN Visa?
The TN (Trade NAFTA) Visa permits citizens of Mexico and Canada to work in the U.S. in specific occupations such as:
- Engineers
- Scientists
- Accountants
- Computer systems analysts
- Medical professionals
- Scientific technicians
- And many more (as outlined in the USMCA occupation list)
To qualify, you must have a job offer in one of the approved categories, meet the educational or licensing requirements, and prove that your stay is temporary.
How to Apply for a TN Visa in the USA (Step by Step)
✅ Step 1: Confirm Eligibility
Before applying, ensure that:
- You are a citizen of Mexico or Canada
- You have a valid job offer from a U.S. employer
- Your profession is on the TN eligible occupation list
- You meet the education or experience requirements for the role
An immigration attorney can help confirm whether your job title and duties match USMCA standards.
✅ Step 2: Gather Required Documentation
You’ll need:
- A detailed offer letter from your U.S. employer
- Proof of educational credentials or professional licenses
- A valid passport
- Any applicable immigration forms (depending on where and how you apply)
We help both employers and applicants ensure that documentation is clear, complete, and properly worded, which is key to avoiding delays or denials.
✅ Step 3: Determine Where to Apply
For Canadian citizens:
- You may apply directly at a U.S. port of entry (airport or land border) without a prior visa.
- Present your documents and undergo an interview with a CBP officer.
For Mexican citizens:
- You must apply through a U.S. consulate in Mexico.
- Complete Form DS-160, schedule a visa interview, and bring your documents.
In some cases, if you’re already inside the U.S., you may be eligible for a change of status. Speak with an immigration attorney to explore this route.
✅ Step 4: Receive TN Status and Begin Work
If approved:
- You’ll receive TN status for up to 3 years (renewable)
- You must only work in the approved position and employer listed
- Any changes (employer, role, location) require new TN documentation
