A TN applicant may be denied admission to the United States or denied approval of a petition or application for TN status or extension, if the Secretary of Labor certifies to the INS that a strike or other labor dispute involving a work stoppage is in progress, and that the temporary entry of the alien in TN status may adversely affect the settlement of the labor dispute or the employment of any person involved in the dispute. A Canadian, who has already engaged in employment in the United States, and who is participating in a strike or other labor dispute, will be considered to be maintaining lawful TN status |
