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.
