On October 1, 2012, USCIS began accepting Forms I-129, the Petition for Nonimmigrant Worker, that were filed on behalf of Canadian citizens who are currently outside the United States and seek to be classified as TN nonimmigrants. USCIS currently only accepts Forms I-129 in connection with requests to extend a TN nonimmigrant’s period of stay or change his or her status to TN.
Canadian citizens will continue to be given the option of applying to the U.S. Customs and Border Protection for TN classification with an application for TN admission to the United States. Learn more about processes for TN (NAFTA) professionals online.
