Canadian Citizens

If you are a Canadian citizen residing outside the United States, you are not required to apply for a TN visa at a U.S. consulate. You may establish eligibility for TN classification at the time you seek admission to the United States by presenting required documentation to a U.S. Customs and Border Protection (CBP) officer at certain CBP-designated U.S. ports of entry or at a designated pre-clearance/pre-flight inspection station.

Canadian Citizens — Form I-129 alternative

Alternatively, a prospective TN employer may choose to file on behalf of a Canadian citizen who is outside the United States by submitting Form I-129, Petition for Nonimmigrant Worker, to USCIS. If USCIS approves Form I-129, you, as a prospective worker, may then apply to CBP for admission to the United States as a TN nonimmigrant by providing the following documentation to a CBP Officer at certain CBP-designated U.S. ports of entry or at a designated pre-clearance/pre-flight inspection station: Proof of Canadian citizenship; and Approval Notice from USCIS for Form I-129. In addition, when applying for admission, you should have in your possession a copy of the Form I-129, and all supporting documentation that was submitted to USCIS, to respond to questions about your eligibility.
