After years of rumors and high hopes, the USCIS has finally announced that Canadian and Mexican citizens applying for TN status may be admitted for up to three years at a time. Previously, they were limited to one-year renewable increments. The TN visa category, created as part of the North American Free-Trade Agreement (NAFTA), allows certain Canadian and Mexican professionals to work lawfully in the United States for US employers. This is very good news for employers, as it will reduce the annual renewal costs and inconveniences for employees holding TN status. The USCIS announcement can be read here.
