How to Apply for TN Status: Canadians vs Mexicans
Immigration » TN visas » How to apply
The steps differ depending on your citizenship. Both routes can lead to the same TN status, but the paperwork and the risk of a refusal at the border are different.
Canadian citizens
- Canadians do not need a visa. They can apply for TN status at a port of entry, at a designated airport with pre-clearance, or through a petition filed by the employer with USCIS.
- At a port of entry, the officer reviews the documents and decides on the spot. A refusal can be difficult to reverse the same day.
- An employer-filed petition can be a better route when there are questions about the profession or the person’s history, or when the person is already in the United States and wants to change status.
Mexican citizens
- Mexican citizens need a TN visa from a U.S. consulate before entering.
- The applicant files the visa application, pays the fee and attends an interview with the job offer letter and credentials.
- After admission, status is granted for the period shown on the I-94 record.
Changing status inside the United States
A person already in the United States in another status can ask USCIS to change to TN with a petition filed by the employer. This avoids a border visit but requires filing early and being patient.
Admission period
TN admission is generally up to three years. Renewals can be requested at the border, through a consulate or with a petition, depending on the person’s situation.
What to bring to the border or the interview
- The employer letter and any contracts.
- Original degrees, transcripts, licenses and evaluations.
- Proof of citizenship.
- Evidence that you plan to return home after the temporary job.
