Some similarities do, however, exist.
Here the similarity ends. Canadians entering the United States in TN-1 status may be admitted in one year increments. An indefinite number of extensions may be granted providing the Canadian professional continues to have a residence abroad they have no intention of abandoning, continues to practice the profession for which they were admitted, and otherwise has complied with the terms and conditions of their status. First time applicants for TN status must appear in person at a U.S. Port of Entry for full inspection and admittance by the U.S. Immigration and Naturalization Service. Extensions of stay may be filed either at the border when crossing, or at the INS Service Center in Lincoln, Nebraska.
