To perform this type of work in the United States, a visa is not required for a Canadian citizen entering as a NAFTA Professional, although a visa can be issued to qualified Canadian TN visa applicant upon request. A Canadian citizen without a TN visa can apply for TN nonimmigrant status at a U.S. port-of-entry. Learn about these requirements on the U.S. Customs and Border Protection (CBP) and U.S. Citizenship and Immigration Services (USCIS) websites. More information about receiving TN status without applying for a visa is also available on the U.S. Embassy Ottawa website.
A Canadian who resides in a third country with a non-Canadian spouse and/or child(ren), and who plans to enter the United States as a NAFTA professional with family member(s), will need a TN visa in order for the family member(s) to be eligible to apply for derivative TD nonimmigrant visa(s).
Mexican citizens require TN visas to request admission to the United States in this status.
