The TN Visa, also known as the USMCA Visa, is a temporary work visa available to citizens of Canada and Mexico under the United States-Mexico-Canada Agreement (USMCA). This visa allows individuals to work in specific professional occupations in the United States and was originally established under the North American Free Trade Agreement (NAFTA).

To be eligible for the TN Visa, you must be a citizen of either Canada or Mexico and have a job offer from a US employer in one of the approved professional occupations listed in the USMCA agreement. You must also possess the necessary qualifications, education, or experience required for the position.

The TN Visa is typically granted for a period of up to three years. It can be extended in three-year increments as long as the individual continues to meet the eligibility criteria.

As of recent updates under the USMCA Agreement, Mexican citizens can now request an additional 12 months, extending the validity of their TN Visa to a total of 4 years per application.

Yes, TN Visa holders can change employers while in the USA, but they must first obtain a new job offer from a US employer in an approved professional occupation. The new employer must file a new TN Visa petition on their behalf.

TN Visa holders can apply for permanent residency (Green Card) if they meet the eligibility requirements for a Green Card in the USA. However, the TN Visa itself is a non-immigrant visa and does not provide a direct path to permanent residency.
