The TN visa is a visa that was established under the North American Free Trade Agreement (NAFTA) and allows Canadian nationals to enter the U.S. as business visitors or to engage in professional activities.

The TN visa is an attractive option for Canadian professionals who desire to work in the U.S. because there are no annual limits to the number of TN visas available each year, the period of admission is for three years and the application may be processed at most U.S. ports of entry and does not require an approved USCIS petition. However, TN visas are not available to self-employed Canadians so the applicant must have a formal job offer from a U.S. employer. Establishing the requirements of a TN visa can be complicated so this is a job that is better left to an experienced TN immigration attorney.
