The TN visa is a special category of non-immigrant visa created by the North American Free Trade Agreement (NAFTA, currently replaced by the USMCA) and was developed to facilitate the entry of qualified professionals from the signatory countries into the United States. This visa type is quite popular among Brazilians, Canadians, and Mexicans who have a job offer in the U.S. and fit the professions specified in the agreement.
When filling out the DS-160, the standard electronic form for non-immigrant visa applications, you will find fields requesting the classification of the visa you are applying for. In the case of the TN visa, the code used is simply “TN”. Therefore, when faced with the question “What is the classification code on the DS-160?”, the correct answer for this process is “TN”.
It is essential, however, to always pay close attention to updates in the form instructions and specific details that may be required by the U.S. Embassy or Consulate where the interview will be held. Following immigration laws and relying on trustworthy sources can help avoid mistakes in filling out the form and complicated situations, including fraud or incorrect information spread through dubious marketing campaigns.
If you have doubts or need detailed guidance on how to complete each step of the DS-160 or the TN visa process, it is important to seek information directly from official U.S. government sources or consult qualified immigration specialists, always remembering that the responsibility for the correct completion of the form lies with the applicant.
