USCIS Updates Adjustment of Status Policy: What Applicants Need to Know in 2026 What Changed Under the New USCIS Policy?…
For foreign professionals who wish to work in the United States, several types of visas are available. One such visa is the Trade NAFTA (TN) visa, which is specifically meant for Canadian and Mexican citizens working in professional occupations under the North American Free Trade Agreement (NAFTA).
The United States-Mexico-Canada Agreement (USMCA) has since replaced the NAFTA. However, the TN visa program remains in effect for Canadian and Mexican citizens under the USMCA.
A TN visa application has several documentary requirements. The principal document is the TN visa letter. This blog explains what a TN visa letter is and how to write it. We also provide a TN visa letter example and some useful tips on preparing a successful application.
The TN visa letter, or TN visa support letter, is an essential part of a TN visa application. It provides a detailed description of the job the applicant is being hired for, their qualifications, and the reasons they are eligible for the TN visa.
The applicant’s prospective employer drafts this letter. It should be presented by the applicant when applying for a TN visa at a U.S. port of entry, consulate, or embassy.
The TN visa Letter not only demonstrates that the applicant is qualified for the TN visa but also indicates that the employer has a thorough understanding of the role and its compliance with NAFTA regulations. The letter can significantly influence the approval of a TN visa application, so careful attention should be paid to its content and presentation.
